Here's something I learned from making my own printed circuit boards. You should ideally actually mirror the image and put the toner side down. That way, light won't come in from the side and creep in under the toner through the transparency. This helps keep lines nice and sharp.
Yes that definitely helps, I would also recommend only using sunlight instead of a UV exposure box because the light is much more parallel and even the tiny gap in between the toner and the photoresist can result in a loss of very fine details
My thoughts exactly! It would definitely be sharper. I guess there might be a slight danger of printer toner sticking to the cyanotype, but I doubt it.
My photoresist loves sticking to the transparency sheets I use, so I have to leave the very thin protective plastic on the top layer. Even though it is much thinner than the transparency itself the difference between sunlight and the LED street lamp I tried to use at first to get consistent exposure time is pretty big.
Mason Daub an LED street light is the wrong kind of light source to use. It contains blue light which will very slowly cure the photoresist, but it's not ideal. You should use UV light. A bigger UV LED nail curing lamp should do the trick.
Yeah I know white LED's don't produce much UV, it's just what I had on hand. If I was going to make a proper exposure box I would order some UV LED strips
@@coolmikefromcanada actually Prussian blue can help you if you have heavy metal exposure. He goes over this and talks about the cool blue cloud in his first video in this seiries
In chemistry-based photography there is the idea of reciprocity, where exposing film or paper for twice as long at half brightness will give the same exposure. ISO 200 film at 1/500th second is the same as ISO 100 at 1/250th. But in really long exposures, on the order of above a minute, there is "reciprocity failure": a ten minute exposure isn't the same as a fie minute exposure one stop down. From your experiment it seems like that may apply to cyanotypes too.
There's also the idea of the Exposure/density curve. This is ideally a straight line for film in the region you're exposing for, but for cyanotype they are very nonlinear with a hard toe and shoulder.
I really love the trial & error aspect of your videos , it feels a lot more organic and is much more entertaining to watch since it's more of an amateur experiment then it is a lecture ( and i use the word amateur really loosely cause clearly you know your science ).

@@AoiFukuyama wow thank you so much!! You helped a lot, i will definitely look into these. I have a Agfa Click 3 inherited from my grandpa, and few undeveloped paper reels from the same. I want to learn more about the camera and the reels before i go trial and error and destroy it 😭. But thanks again, you made my day soooo muchhhh betterrrr... Sending all the good vibes to you.
More of this please! This perfectly ties up all of the videos you've done about dyes/pigments etc. Curious about other chemistry + photography connections, there isn't nearly enough good info out there like this video.
In the final scene, did you just expose FAC coated paper and then brush on PF? That's allegedly how Herschel did it though we haven't tried ourselves. Very enjoyable series seeing you come at it from a different angle. If you try other recipes doing your first rinse in 1% Citric Acid lowers the contrast and helps other tones to the party. There are also a few published curves for Photoshop to adjust the tones for better representation. A Photoshop script called Chartthrob (Free) can be used to generate your own curves. Lastly, we never have luck making laser digital negatives. Inkjet is much better but make a test to see which color ink in your printer blocks the most UV. Reddish orange Canon inks work much better than black for us.
This is one of my favorite series you've done. As a photographer I love seeing the classic work you've done, as a nerd I love seeing how you're doing it. Bravo!
Here are a couple tips that I think could help. The negative is one of the most important things so you can convert the color image into a halftone first before inverting to a negative. This will allow you to adjust your levels more equally for just a single color exposure like your doing here or even for the duo tone. Also place the emulsion side of your negative closest to the paper, this will allow for less uv light to "bleed" under the blacked out portions which is a result of the very minute thickness of the transparent layer and you can also buy thinner transparency to reduce the amount of uv light to bleed. The closer you can get your negative to lay to the paper the better your result will be. In the print shop we vacume the negative down to the paper to get it as close as possible. Makes a huge difference. Also you could try a lower dpi "dots per inch" on the printer when printing the negative. Sometimes higher dpi washes out even though it's better quality some paper just can't hold it so try lowering the dpi to like 300 or 200 or 150 and see the difference in results. These are all things you can do that I feel would really help. I think it would be awesome to get some blueprints with lots of linework to expose. Like the Eiffel tower or the colleseum.
This is what I think caused some difficulty with dialing in the exposure of the print. When enlarging from film negatives (assuming the film was properly exposed and developed) you have information all over the negative and can adjust the exposure of the print gradually. If the digital image has too much contrast the properly exposed region between underexposed --> no detail
singapore represent babey!! i love the photo at 22:48 and all of the reactions/timelapses. this was so cool to watch i hope i get the time/opportunity to do this one day
I would love to see a video on 6,6'-dibromoindigo, AKA Tyrian purple. A very historically significant dye, and one that was incredibly expensive before it could be synthesized, due to how many snails had to be collected to extract a useful amount of it.
7:30 "it can be a disaster" I actually sincerely enjoyed the rougher outcome more than the higher quality prints you produced later in the video; it gave it a lot of character that you lose with a perfect print.
What I really like about your videos is that the quality is so constant. As far as I can remember, your videos have always delivered and it makes me happy even seeing there's a new one to watch. It's a rare feeling these days on youtube. Thanks!
I always enjoy your videos greatly, but this one is, as of yet, my favorite video of yours. Some years ago, I started out with digital photography but not long after moved into film photography and darkroom processes, then followed by historical photographic processes. To see you go through step-by-step the recreating of what was done in the 1860s and on is quite fantastic. Trying to get the chemistry of the process properly working, to compensate exposure, to test different exposures and times of the day right for UV light, the way you test exposures by exposing the image for different times to check the density... You even got to the basis of density (Dmax) and reciprocity charts. It's all exactly what was and still is done in the making of a photographic print. *THIS* is the basis behind all the research and standardization in the photographic industry, creating UV-exposure units and emulsion-coating. It's what Kodak and Fuji, among many other chemical/photographic industries, did up until quite recently in 2004 when digital started to take over the market. As I said before, this is a fantastic work and video. Congratulations.
Also, I'd like to see more videos on early photographic processes. You still have all that mercury, right? Daguerrotypes, perhaps? (I may even be convinced to build you a simple camera for it in exchange for a beaker, I got a couple of old lenses laying around.)
As a person coming from the art side of this, I am quite impressed at what you accomplished in this series. It taught me more about the science of cyanotyping, and I really enjoyed seeing how you used the medium!
The non-linear exposure response over time has been known for a very long time in the film world. A specific example is film-make star trail images. If an exposure is made over 2 hours, the stars move, making a trail for each visible star. However, on film, each trail begins to fade out, as the exposure time / effect begins to diminish. This effect is called reciprocity failure, and is exactly what you describe here. Charts are/were even distributed to help photographers deal with the phenomenon on long exposures. www.ilfordphoto.com/wp/wp-content/uploads/2017/06/Reciprocity-Failure-Compensation.pdf
As a photographer, I have, in the dim distant past, worked with "Printing Out Paper" in contact frames. The paper and negative are pressed between an opaque back and glass front. The frame keeps the neg and paper absolutely flat. The second piece of glass allowed diffused and reflected light to expose the paper from the back and cost sharpness and definition. Very nice chemistry lesson., Thanks
PRINTER REPAIR MAN HERE, your drum is worn, those bubble looking lines are from the developer unit which should be part of the toner / drum cart, sometimes the corona wire gets dirty and you can clean it with a slide wipe that is usually part of the unit between the drum and toner reservoir.
The emulsion of the two solutions changed color just like if you were mixing paints, the FAC is a dark green, and the PFC is a lighter orange. It's a super fine dispersion of different colored particles that appear as a solid color from a distance
Umm, no? It is actually pretty similar to exp(-x), the exponential decay. It is encountered pretty often while studying reaction rates (first order kinetics to be specific).
The rapidly rising exposure time for doubling darkness (density) is called reciprocity error in analog photography. You don't usually notice it below exposures of 1 second. But starting at 1 second, you might have to expose a lot longer than usual. This is of a lot of importance of people who do night photography.
Interesting. I have done a lot of long exposure night shots, but ive only used a digital camera, so i dont think those same issues arise. With digital, i think the rate is practically constant. Correct me if im wrong though.
Digital sensors don't have that kind of non-linearity in the exposure time-density relation, so you won't notice it with digital cameras. By the way, did you know you can develop photographic film and paper with coffee powder, ascorbic acid and sodium carbonate? It is a pretty cool chemistry party trick and relatively safe.
I did that in college: we made iron-based photosensitive pigment and coated paper, then used that in a 4x5 box camera. I recall one student had a photo of a clock and you could see the motion blur in the minute hand, showing how the exposure was so slow.
This is a very useful video. I have started trying to replicate your process since the previous video and this one adds quite a few helpful details! I loved the extra bit on toning the prints at the end, beautiful results!
To work with watercolor paper the best way without getting it to wrinkle or expand is to presoak it in a low level of water for a few seconds and then lay it in a flat suface and fix it with kraft gummed paper tape and then allow it to dry. Once dry it's ready to be used and it won't shrink or expand
Great video! How do you recommend a lay person become competent in chemistry? I can’t afford to take a ton of classes outside my major, but I want to become knowledgeable at a high level in chemistry
I would look into MOOC opportunities. These are Massive Online Open Courses and are essentially (usually) free online based courses with aims of reaching many people. These are a good bet and usually easy to find. Many universities have their classes recorded and used for these giving you the same knowledge, just not the hands on experiences associated with those classes
Skillshare maybe? Also, I would honestly invest in a 'little chemist" set, for kids. Most of them are trash, but there are few that come with accual chemicals and hundreds of experimens
If you're just "some guy" with no chemistry background, you'll land on several government lists for ordering certain chemicals and glassware. So, watch it. If you decide to go forward, make sure you never order or make any DEA listed chemicals. Also, have someone teach you basic lab safety precautions. You can't replace your eyes.
I have no interest in chemistry and I couldn't care less for your videos but your voice is the perfect white noise to keep me company when doing house chores. Thank you for that.
Idk, I'd have used the canvas boards & gesso to get rid of textures if you didn't want textures. Another thing my daughter loves painting on is thinner high-quality MDF, cut into the shape she wants. She adds pouring medium to her primer, pours the paint on & then she used a metal blade that you use for drywall, she also has a tool that resembles a metal squeegee or piece of glass to give herself a non-textured base to start with. I think if you cut out the thin MDF into an octagon (like a stop sign...or cut it into another shape), prepped it in the way that I explained above & printed out one of your favorite pics from a decent cam that it would make an excellent gift or cute decor in your home. To finish it, pick up some picture frame or wall mirror hanging hardware & install them on the back & spray it with either a clear coat of acrylic protectant clear coat or you could even give it a pour of clear epoxy if you want it to have a shinier finished look & be exceptionally durable. My daughter cut out a 4 foot tall shape of a beer bottle; expanding the rest of the dimensions to maintain the perfect look. She prepped it, painted a background made up of things you'd find if you entered a very cool bar, got prints of my sister & her friends, glued them to the places she left open for the prints to make them resemble bar coasters (I'd imagine something like my daughter's piece would look very cool if you used the print style used in this video & doing something else such as maybe cutting a boat shape & printing using family pics of caught fish prints as licenses over a background using different painted lures or something), let everything dry & poured a thin coat of clear marine epoxy over the piece. She used her heat gun to disperse the bubbles (you can also use the spray they sell for this purpose), let it dry completely, sanded it, polished it & added the hanging hardware to the piece. Idk, cool video.
He wasnt sure it was a scam (and not the product but the ad contract), what he focused on and what was the message of the video was that you should really use and get to know the products you advertise, and only advertise those that you think are really valuable to you and your audience, otherwise you will lose credibility, and in the end you will lose more money because of your lack of credibility that what you make for those ads.
Just watched Rossmann's video... it doesn't specifically state that their service doesn't work, but it clearly shows how they reach out to creators is less-than-reputable... damn
I teach high school art. I love collaborating with our chemistry teacher to do cyanotypes with our classes. His classes prepare the solutions, mine prepare the negatives, everyone gets cool prints! They really enjoy the hydrogen peroxide trick. Another toning option is bleaching and then using the Van Dyke Brown method and re-exposing with the same negative. You get some really cool blue and brown color effects. One more thing to keep in mind is accounting for the thickness of the transparency film. I always flip the image horizontally so it is backwards so I can place the printed side down on the paper. It's a small detail, but light can get under the toner if the printed side is on top and can cause a tiny amount of fuzziness. Perhaps not a big deal to most, but i do like my prints to have the sharpest detail i can get!
1:20 I actually made blueprints in this way in about 2001 when I was learning to weld. Even though this process was no longer used to produce blueprints in the industry. At the time they were still teaching this, but I don't think they do any more.
This is outstanding. I'm getting ready to play with cyanotype (I got the premixed stuff), and all of your experimentation in this video got me all excited to get at it. Thank you for all this work.
This process is all about making printing out paper or POP for short. A century ago, many cameras used large glass plates as film. Some were 8X10-inches in size or larger, and they were placed in a printing frame with a sheet of POP and taken into the sunlight. When the paper turned a particular color, it was taken to the darkroom and processed. Some of the best quality photos of all time were printed in this manner. You do need to size the paper, and use the best quality paper possible. Paper that is made from rags and acid free is what you need for quality prints. A UV lamp would make your printing process more repeatable. Also, there is another printing process based on platinum. You can see prints made this way in museums.
That observation about how the longer the exposure the lower the concentration of unexposed FAC there is is similar to the concept of reciprocity failure in film photography. Basically, during long exposures the longer you expose the film, the less of the emulsion is still light sensitive and you have to account for that depending on your film.
The falloff of the relation between exposure time and print density happens with film too, it's called reciprocity failure. Most film stocks begin experiencing reciprocity failure after just a few seconds, but some others (Fuji Acros and Fuji Provia for example) can go up to two minutes before it kicks in.
you just gave me an idea on how to re-paint jeans and other stuff with sunlight, cause the chemical reaction fixes the prussian blue (which is a pigment and not a dye), I believe this coloration will be longer lasting than regular dyed stuff! Cheers for that!
Besides controlling exposure, you can fine tune how your cyanotype comes out by downloading custom curve presets and applying them to your negative in Photoshop. They are meant to add the correct amount of contrast and sharpness to produce the best result for a homemade cyanotype.
I love this. Particularly fascinating to me since I've recently gotten into developing my own film and making prints (old darkroom equipment is super cheap right now).
I just watched this video this morning and then today at work happened upon some really cool old cyanotype blueprints of the Charlottesville, VA airport.
I'm a photographer and I definitely wouldn't consider 22:48 underexposed. Even the pre-toned one looked acceptable to me.

I want to learn more about the camera and the reels before i go trial and error and destroy it 😭. But thanks again, you made my day soooo muchhhh betterrrr... Sending all the good vibes to you.
I know that technology connections channel did a whole series on photos and how to develop and how they used to be developed etc
More of this please! This perfectly ties up all of the videos you've done about dyes/pigments etc. Curious about other chemistry + photography connections, there isn't nearly enough good info out there like this video.
I'm really glad you liked it! :)
In the final scene, did you just expose FAC coated paper and then brush on PF? That's allegedly how Herschel did it though we haven't tried ourselves.
Very enjoyable series seeing you come at it from a different angle. If you try other recipes doing your first rinse in 1% Citric Acid lowers the contrast and helps other tones to the party. There are also a few published curves for Photoshop to adjust the tones for better representation. A Photoshop script called Chartthrob (Free) can be used to generate your own curves.
Lastly, we never have luck making laser digital negatives. Inkjet is much better but make a test to see which color ink in your printer blocks the most UV. Reddish orange Canon inks work much better than black for us.
The experiment is in-depth and professional. It's hard to find videos on TH-cam with such quality. As always, great video.
the one you let sit directly in the tea looked the best! you could actually see the wetness of the rain on the tents!
This is one of my favorite series you've done. As a photographer I love seeing the classic work you've done, as a nerd I love seeing how you're doing it. Bravo!
"The Gayest Person on Patreon", "I'm sorry mistress" and "I'm SURE I can fit them all in my mouth" are the best names on your Patreon :X
bruh
I love how methodical your videos are. Much respect, sir!
alot of this i already learned from a black and white photography class, but its very interesting to see someone with no experience's take on it.
I'm an artist and this video inspired make some prints! I ordered everything I need and can't wait to see how everything will turn out!!!
@Silicon Nomad its not gonna happen
Here are a couple tips that I think could help. The negative is one of the most important things so you can convert the color image into a halftone first before inverting to a negative. This will allow you to adjust your levels more equally for just a single color exposure like your doing here or even for the duo tone. Also place the emulsion side of your negative closest to the paper, this will allow for less uv light to "bleed" under the blacked out portions which is a result of the very minute thickness of the transparent layer and you can also buy thinner transparency to reduce the amount of uv light to bleed. The closer you can get your negative to lay to the paper the better your result will be. In the print shop we vacume the negative down to the paper to get it as close as possible. Makes a huge difference. Also you could try a lower dpi "dots per inch" on the printer when printing the negative. Sometimes higher dpi washes out even though it's better quality some paper just can't hold it so try lowering the dpi to like 300 or 200 or 150 and see the difference in results. These are all things you can do that I feel would really help. I think it would be awesome to get some blueprints with lots of linework to expose. Like the Eiffel tower or the colleseum.
This is what I think caused some difficulty with dialing in the exposure of the print. When enlarging from film negatives (assuming the film was properly exposed and developed) you have information all over the negative and can adjust the exposure of the print gradually. If the digital image has too much contrast the properly exposed region between underexposed --> no detail
22:48 that is just amazing!!! , i would never think twice before hanging this in my room , so good !
singapore represent babey!! i love the photo at 22:48 and all of the reactions/timelapses. this was so cool to watch i hope i get the time/opportunity to do this one day
I would love to see a video on 6,6'-dibromoindigo, AKA Tyrian purple. A very historically significant dye, and one that was incredibly expensive before it could be synthesized, due to how many snails had to be collected to extract a useful amount of it.
I very much love these practical applications of chemistry. Would love to see you cover more of these, including toning, in future videos!
The one thing about Art is that even if these pictures aren't perfect, they're still beautiful. 😌

bill wurtz's history of the entire world, i guess
idk how its relatable to this video, but the sun is a deadly laser making cyanotypes
even the overexposed shot looked really cool..i LOVE the effects you are getting with this method!!
7:30 "it can be a disaster" I actually sincerely enjoyed the rougher outcome more than the higher quality prints you produced later in the video; it gave it a lot of character that you lose with a perfect print.
What I really like about your videos is that the quality is so constant. As far as I can remember, your videos have always delivered and it makes me happy even seeing there's a new one to watch.
It's a rare feeling these days on youtube. Thanks!
Thanks, i appreciate it!
I wish my school chemistry lessons were this applicable.
I always enjoy your videos greatly, but this one is, as of yet, my favorite video of yours.
Some years ago, I started out with digital photography but not long after moved into film photography and darkroom processes, then followed by historical photographic processes. To see you go through step-by-step the recreating of what was done in the 1860s and on is quite fantastic.
Trying to get the chemistry of the process properly working, to compensate exposure, to test different exposures and times of the day right for UV light, the way you test exposures by exposing the image for different times to check the density...
You even got to the basis of density (Dmax) and reciprocity charts.
It's all exactly what was and still is done in the making of a photographic print. *THIS* is the basis behind all the research and standardization in the photographic industry, creating UV-exposure units and emulsion-coating. It's what Kodak and Fuji, among many other chemical/photographic industries, did up until quite recently in 2004 when digital started to take over the market.
As I said before, this is a fantastic work and video. Congratulations.
Also, I'd like to see more videos on early photographic processes. You still have all that mercury, right? Daguerrotypes, perhaps? (I may even be convinced to build you a simple camera for it in exchange for a beaker, I got a couple of old lenses laying around.)
Daguerrotypes are very dangerous to make due to the way the mercury is used. Photographers went blind, or mad from mercury poisoning.
@Silicon Nomad good point
@@taraswertelecki3786 but now we have better protective gear and better safety
As a person coming from the art side of this, I am quite impressed at what you accomplished in this series. It taught me more about the science of cyanotyping, and I really enjoyed seeing how you used the medium!
The non-linear exposure response over time has been known for a very long time in the film world. A specific example is film-make star trail images. If an exposure is made over 2 hours, the stars move, making a trail for each visible star. However, on film, each trail begins to fade out, as the exposure time / effect begins to diminish. This effect is called reciprocity failure, and is exactly what you describe here. Charts are/were even distributed to help photographers deal with the phenomenon on long exposures.

I been waiting for this one, it was worth it. I love the results, especially the non bleached and toned one, beautiful colour.
This is very satisfying to watch (development)
I agree! but not as satisfying as wen actually doing it in a darkroom
As a photographer, I have, in the dim distant past, worked with "Printing Out Paper" in contact frames. The paper and negative are pressed between an opaque back and glass front. The frame keeps the neg and paper absolutely flat. The second piece of glass allowed diffused and reflected light to expose the paper from the back and cost sharpness and definition. Very nice chemistry lesson., Thanks
"Tanin solution" Straight up cup of coffee 😆
Ikr :D a true chemist.
It’s important to note that the art paper is not only thicker and more durable but acid free which could likely help with the cyanotyping process
Bases actually bleach cyanotypes. You have to avoid buffered paper.
Would you mind uploading that photo from Singapore on imgur or something like that ? I really love photos like that with the rain and such
PRINTER REPAIR MAN HERE, your drum is worn, those bubble looking lines are from the developer unit which should be part of the toner / drum cart, sometimes the corona wire gets dirty and you can clean it with a slide wipe that is usually part of the unit between the drum and toner reservoir.
The cover of the Elliott Smith album "Elliott Smith" was done in cyanotype.
It was the first thing that I associated with the thumbnail of this video.
The emulsion of the two solutions changed color just like if you were mixing paints, the FAC is a dark green, and the PFC is a lighter orange. It's a super fine dispersion of different colored particles that appear as a solid color from a distance
13:45,
This graph does not show exponential, it shows rational, just for these math purists.
Umm, no? It is actually pretty similar to exp(-x), the exponential decay. It is encountered pretty often while studying reaction rates (first order kinetics to be specific).
The rapidly rising exposure time for doubling darkness (density) is called reciprocity error in analog photography.
You don't usually notice it below exposures of 1 second. But starting at 1 second, you might have to expose a lot longer than usual. This is of a lot of importance of people who do night photography.
Interesting. I have done a lot of long exposure night shots, but ive only used a digital camera, so i dont think those same issues arise. With digital, i think the rate is practically constant. Correct me if im wrong though.
Digital sensors don't have that kind of non-linearity in the exposure time-density relation, so you won't notice it with digital cameras.
By the way, did you know you can develop photographic film and paper with coffee powder, ascorbic acid and sodium carbonate? It is a pretty cool chemistry party trick and relatively safe.
LimaVictor I had no idea!
I am not gonna lie I nearly screamed when he said he took the photo in Singapore
Singapore gang where y’all at
I did that in college: we made iron-based photosensitive pigment and coated paper, then used that in a 4x5 box camera. I recall one student had a photo of a clock and you could see the motion blur in the minute hand, showing how the exposure was so slow.
THANK YOU! i was going insane due to boredom this helps a ton.
Been waiting for this last video for over a month now FINALLY
ha, I finally delivered.
SCIENCE

CHEMISTRY
Bitch!
you ruined it.
Ritik Sharma you ruined it, so you're the bitch. bitch.
After watching this video, the history of photography I learned about in my intro art class makes so much more sense!!
You should consider a video about photoresist!
I got completely hypnotized by all three videos because blue is my favorite color lol
This is a very useful video. I have started trying to replicate your process since the previous video and this one adds quite a few helpful details! I loved the extra bit on toning the prints at the end, beautiful results!
I'm glad you liked it!
To work with watercolor paper the best way without getting it to wrinkle or expand is to presoak it in a low level of water for a few seconds and then lay it in a flat suface and fix it with kraft gummed paper tape and then allow it to dry. Once dry it's ready to be used and it won't shrink or expand
Great video! How do you recommend a lay person become competent in chemistry? I can’t afford to take a ton of classes outside my major, but I want to become knowledgeable at a high level in chemistry
Will E I would also be interested in the responses to this!
Will E same here.
I would look into MOOC opportunities. These are Massive Online Open Courses and are essentially (usually) free online based courses with aims of reaching many people. These are a good bet and usually easy to find. Many universities have their classes recorded and used for these giving you the same knowledge, just not the hands on experiences associated with those classes
Skillshare maybe? Also, I would honestly invest in a 'little chemist" set, for kids. Most of them are trash, but there are few that come with accual chemicals and hundreds of experimens
If you're just "some guy" with no chemistry background, you'll land on several government lists for ordering certain chemicals and glassware. So, watch it. If you decide to go forward, make sure you never order or make any DEA listed chemicals. Also, have someone teach you basic lab safety precautions. You can't replace your eyes.
I have no interest in chemistry and I couldn't care less for your videos but your voice is the perfect white noise to keep me company when doing house chores. Thank you for that.
You could have used these strips as a dosimete-
Oh.
Idk, I'd have used the canvas boards & gesso to get rid of textures if you didn't want textures. Another thing my daughter loves painting on is thinner high-quality MDF, cut into the shape she wants. She adds pouring medium to her primer, pours the paint on & then she used a metal blade that you use for drywall, she also has a tool that resembles a metal squeegee or piece of glass to give herself a non-textured base to start with.
I think if you cut out the thin MDF into an octagon (like a stop sign...or cut it into another shape), prepped it in the way that I explained above & printed out one of your favorite pics from a decent cam that it would make an excellent gift or cute decor in your home.
To finish it, pick up some picture frame or wall mirror hanging hardware & install them on the back & spray it with either a clear coat of acrylic protectant clear coat or you could even give it a pour of clear epoxy if you want it to have a shinier finished look & be exceptionally durable.
My daughter cut out a 4 foot tall shape of a beer bottle; expanding the rest of the dimensions to maintain the perfect look. She prepped it, painted a background made up of things you'd find if you entered a very cool bar, got prints of my sister & her friends, glued them to the places she left open for the prints to make them resemble bar coasters (I'd imagine something like my daughter's piece would look very cool if you used the print style used in this video & doing something else such as maybe cutting a boat shape & printing using family pics of caught fish prints as licenses over a background using different painted lures or something), let everything dry & poured a thin coat of clear marine epoxy over the piece. She used her heat gun to disperse the bubbles (you can also use the spray they sell for this purpose), let it dry completely, sanded it, polished it & added the hanging hardware to the piece.
Idk, cool video.
Careful with NordVPN, i saw Louiss Rossmann read there contract, it was really bad.
what do you mean?
I think rossman stated he thought it was a scam. As a client of NordVPN, I couldn't be more happy.
He wasnt sure it was a scam (and not the product but the ad contract), what he focused on and what was the message of the video was that you should really use and get to know the products you advertise, and only advertise those that you think are really valuable to you and your audience, otherwise you will lose credibility, and in the end you will lose more money because of your lack of credibility that what you make for those ads.
I guess you're talking about this video
/watch?v=VrME4kn15rQ
Just watched Rossmann's video... it doesn't specifically state that their service doesn't work, but it clearly shows how they reach out to creators is less-than-reputable... damn
I bought a kit. I fell in love with the process and can't wait to try it myself. Thank you!
Could you somehow mask part of the photo during the toning? Like block the sky so it stays blue while the subject turns brown?
You could probably try coating parts you don't want to tone with paraffin.
That Singapore photo was perfect for this! All the prints of that shot were beautiful imho!
1:32
Yeah sure, “ferric ammonium citrate”
This is the most artistic corner of chemistry 👍
8:03 am I colour-blind? It looks greenish blue to me.
Yeah, it kind of does to me as well. I'm not colorblind though, I'm fairly sure about that.
Best run through of the cyanotype process Ive seen so far!
Science is cool
I teach high school art. I love collaborating with our chemistry teacher to do cyanotypes with our classes. His classes prepare the solutions, mine prepare the negatives, everyone gets cool prints! They really enjoy the hydrogen peroxide trick.
Another toning option is bleaching and then using the Van Dyke Brown method and re-exposing with the same negative. You get some really cool blue and brown color effects.
One more thing to keep in mind is accounting for the thickness of the transparency film. I always flip the image horizontally so it is backwards so I can place the printed side down on the paper. It's a small detail, but light can get under the toner if the printed side is on top and can cause a tiny amount of fuzziness. Perhaps not a big deal to most, but i do like my prints to have the sharpest detail i can get!
Will you be doing a video on making psychedelics from scratch for educational purposes (no, literally for educational purposes)
lenny face is all I can answer you my friend...
1:20 I actually made blueprints in this way in about 2001 when I was learning to weld. Even though this process was no longer used to produce blueprints in the industry.
At the time they were still teaching this, but I don't think they do any more.
Hey nilered why don't you make iodoform?
You have an eye for photography too! Well done - I’ve really enjoyed this series.
Too much of 'though'. Just an observation.
This is outstanding. I'm getting ready to play with cyanotype (I got the premixed stuff), and all of your experimentation in this video got me all excited to get at it. Thank you for all this work.
Early
This process is all about making printing out paper or POP for short. A century ago, many cameras used large glass plates as film. Some were 8X10-inches in size or larger, and they were placed in a printing frame with a sheet of POP and taken into the sunlight. When the paper turned a particular color, it was taken to the darkroom and processed. Some of the best quality photos of all time were printed in this manner. You do need to size the paper, and use the best quality paper possible. Paper that is made from rags and acid free is what you need for quality prints. A UV lamp would make your printing process more repeatable. Also, there is another printing process based on platinum. You can see prints made this way in museums.
1 view :O
That observation about how the longer the exposure the lower the concentration of unexposed FAC there is is similar to the concept of reciprocity failure in film photography. Basically, during long exposures the longer you expose the film, the less of the emulsion is still light sensitive and you have to account for that depending on your film.
I’ve always been more into physics than anything, but your videos have really peaked my interest into chemistry again thank you
Prussian blue is so gorgeous, you did a fantastic job
The falloff of the relation between exposure time and print density happens with film too, it's called reciprocity failure. Most film stocks begin experiencing reciprocity failure after just a few seconds, but some others (Fuji Acros and Fuji Provia for example) can go up to two minutes before it kicks in.
That was an amazing print of Singapore. Brings back some good memories.
My printmaking personal life is proud of you. Hurray for the printed multiple and the celebration of film/photo developing.
you just gave me an idea on how to re-paint jeans and other stuff with sunlight, cause the chemical reaction fixes the prussian blue (which is a pigment and not a dye), I believe this coloration will be longer lasting than regular dyed stuff!
Cheers for that!
Besides controlling exposure, you can fine tune how your cyanotype comes out by downloading custom curve presets and applying them to your negative in Photoshop. They are meant to add the correct amount of contrast and sharpness to produce the best result for a homemade cyanotype.
I love this. Particularly fascinating to me since I've recently gotten into developing my own film and making prints (old darkroom equipment is super cheap right now).
idk why but i find this video the coolest thing ever.
I just watched this video this morning and then today at work happened upon some really cool old cyanotype blueprints of the Charlottesville, VA airport.
