Making a Gelatin Emulsion

- Did you know the substance that allows us to capture images on glass, is the same as what we use on 35mm film and other light-sensitive products? Nick Brandreth, Historic Process specialist at the George Eastman Museum, shares what goes into making a gelatin emulsion, one of the magical ways we can capture images.

Great demonstration, I do hope you will make more videos of making glass plate negatives
Fascinating, and several steps I wouldn't have thought. This is going to make a much greater demo than just naked crystals, thank you!
I'm looking forward to this workshop @ the GEM..
Miss u Nick
does it works for makeing holograms (with laser) ? Thank you
Would you please provide the specific ratios of these substances?
Just what I was looking for as I would like to make again plates to use in old cameras...just.....this is very condensed, do you have a long version, more explanations or a link to a document explaining the process in more details? Thanks !
Please visit eastman.org/workshops for more information! We will be hosting a virtual workshop for gelatin emulsion making in the near future, and we do offer private tutorials.
@@GeorgeEastmanMuseum cool, thanks for the info
can you show me the amount of stuff that i have to make the emulsion?
Friend please I hope that you can answer my question, I am from Mexico 😊 I am 21 years old I am trying to make my first analog photo but sadly here in Mexico there aren't rolls 35mm to take photos, and I was thinking about making a Pinole camera but sadly there isn't sensitive paper and even on internet there is not stock I mean that hardly I couldn't get any of them , so I was thinking about Cyanotype technical using turmeric , is there a way that I can make an analog photo wearing home articles ?
Nice experiment.
I think I will give it a try some day.
For developing you use regular bw developer like rononal?
Correct
I just bought a 1902 Pony Premo and would love to try this - where is the best place to buy the chemicals needed?

Since this is an orthochromatic emulsion, then how do you make a panchromatic emulsion?
Can i use it on paper?
Hello.
I am a Korean subscriber.
I heard that the melting point of gelatin in silver gelatin emulsion is about 25 degrees.
In Korean summer, the temperature rises to 35 degrees Celsius. Wouldn't the silver gelatin emulsion film melt like this?
Is there a solution to this?
Gelatin's melting point when its soaked with water is closer to 37C.. However once your emulsion is dried onto glass, you don't have anything to worry about.. The main difference between your film and a dry plate is just the support base. That said, you DO have to worry about temps being to high when processing your plates.. If your processing chemistry is TOO HOT your gelatin can dissolve off the plate. To combat this you'll want to harden your emulsion by adding some chrome alum. Please feel free to e-mail me with further questions. Nbrandreth@eastman.org
t 1:10 where you filtering the emulsion before chilling? I usually do that after noodeling/washing and remelting.
I filter the emulsion when pouring it into the tray for chilling, after my remelt before washing and right before I coat. I simply run the gelatin thru a gold coated coffee filter. This helps reduce bubbles and will catch any thing that might have fallen out of solution.
@@nickbrandreth which brand gelatin I'll work for emulsion
And how to make POG with hologram? Such toys use plastic sheet, but not glass
Will this coat Perspex? I want to make a cyanotype onto Perspex. Also what are the measurements for these chemicals? :-) thanks

I wonder how this affect was discovered in nature?
Obvious accident
Hello.
I am a South Korean subscriber. Can you know the whole recipe? How many grams of silver nitrate, how many grams of potassium bromide, and how long does it take to ripen? Sorry for not knowing your language.

If the world ends I will still be able to take photos
I know that people make their own emulsion for plate photography all the time, but is it out of the reach of a hobbyist to make their own film with homemade emulsion? It's something I've been thinking about for a while, even going as far as reading old patents and so forth, but most of that information applies more to the industrial processes and machinery used 100 years ago. I'm not looking to run a factory, just smear some emulsion on some plastic film.
We are running two workshops in March and April on how to make gelatin emulsions at home! Learn more at eastman.org/Darkroom.
Gday Why isnt 35m film recipe/design/instructions released for FREE
for the WORLD as patent free , royality free knowledge for humanity ?
It pretty much is you just have to dig around a lot and sift through old public patents. I'm currently putting together a book that goes over how to make actual colour negative and B&W film at home and I hope to be done in a year.
@@rorythorns1597 Consider me VERY interested.
@@rorythorns1597 have you written it yet?
@@rorythorns1597 holy you were not wrong - but these are all for basic formulas - patents listed for specific production rolls? Like would Porta 400 have a different formula than Gold200?
This is a show off video as there are no measurements/volumes or amounts. What a waste of time.
It's obvious you missed all the comments (see above) which give direct email addresses for the smart people at the George Eastman Museum. I suppose no-one's bothered replying to your comment because, you know: who wants to bother with a whiny, lazy, bitchy little goof? You're most welcome - thumbs WAY up! :)
@@TheStockwell Hey Twat!! Its a nothing video . Think of a clever reply... well smarter than the last one anyways.
Hi Cole, please contact workshops@eastman.org for more in-depth information. We offer virtual workshops and private tutorials if you would like the full recipe!
@@colebest3457 Sorry, Cole, but complaining and being a immature little troll isn't my style. It's yours. Embrace it! Thoughts and prayers for a speedy recovery! 💒🌵🐱🐧🐰🐴
@@GeorgeEastmanMuseum You people are SO patient with abusive pests with no-content channels! I'm hoping to visit the Museum this year if the pandemic subsides. I work with vintage Kodak cameras. My latest acquisition: a No.1 Brownie. It's missing a few parts, which is why I was able to afford it. I'm pretty sure I can reverse engineer it so it's ready for its 121st birthday. ☺
