There are very few videos covering this subject, so it's always a pleasure to see a new one. One tip: Most B&W developers use metol as a core developing agent. It is relative hard to dissolve in water. So, into your water first add a "pinch" of the sodium sulfite and let that dissolve. It will protect the metol from oxidizing while it is taking its time to dissolve, which is why his straight dissolve of his metol turned a little brown - oxidation. Then just add and dissolve the rest of the metol. Note that if you first just add and dissolve all of the sulfite, that concentration of sulfite in the water will make it practically impossible to thereafter dissolve the metol, so just a little bit at first.
Hey Thanks, Huh hard to tell as I haven't tested it that much but I would say a lot. If I remember I will reply you with a number when I make the tests :)
Hi, I am from India and I really like your videos and enjoy these tutorials that you upload with your regular contents. I was wondering if you can upload a video on how to make dry plate emulsion from scratch that will be of great interest and benefit for a lot of your viewers. Thank you and keep up the great work... :)
Would this work with bucket developing reversal 16mm B&W film? I've been using cafenol (instant coffee, vitamin c powder, washing soda) and its been working but looking for something more refined. Great video !
In the US, there are still three or four companies which supply raw photo chemicals, and th ones used here are very basic, so available. Photographer's Formulary in Montana is probably the best known. The cost of mixing equipment, like that magnetic shirring base, has been coming down over the years, and digital thermometers are cheaper and more accurate than the old lab types.
Nice video. Do you think the home-made chemicals would somehow offer a better performance rather then the commercial ready-to-use products? Do you manage to prepare your stop & fix as well? thanks^^
Hey Jacopo. From my experience there is no noticeable difference between the homemade and original. However you can always tweak your own stuff to meet your requirements. I will be making a video on the fixer as well just stay tuned :)
The colour of your solution is caused by the Metol oxidising. By adding a pinch of Sodium Sulfate before the Metol you will avoid this oxidation. Otherwise enjoying your mix of vlogs etc.
Did you try to use this developer with x-ray film? (I'm curious about the results with portraits and landscepes.) Also, can you tell what is the life-time of this developer with moderate using and storing in the fridge?

Hey Randal,
Thanks for your explanation and tips really appreciate it!
Outstanding video. I really love what you do.
Thanj you 🙏
Wonderful video .Thank you for details
You are welcome 🤗
good video, as always
would love to see you make Pyro developer
Thanks Charles. Noted 😊
Very interesting (and economical?). Thanks for sharing.
Hey,
If you buy chemicals localy then yes 😊
Very interesting and good video :)
Thanks
I'd love to watch the video about home made liquid emulsion,
This is for sure gonna happen when I have more time to film it :)
Thank you!
You are welcome :)
Maybe a video about sandarac warnish or an alternative to it.
Noted. This will all be explained and showed when I start making episodes on how to recreate autochrome :)
Thanks for providing good information! How many 4x5 inch plates can d19 1L developers develop?

Hey. It's on my priority list for sure!
Thanks for the video. Have you made D23 Metol developer; if so what’s your opinion and is it a good option for dry plate ? Thanks.
Hey Paul. I haven't

Wonderful 😎😎😎
Thanks 🤗
@@lostlightart6064 Don't forget to cover the C41... Looking forward to you.
Thanks for this video ! Is it easy to buy the raw chemicals products?
Hey Marcel. Thanks for the comment. Yes its fairly easy some of them like metol are a bit more tricky but there are many options out there ;)

@@randallstewart175 Thanks Randall !
Its better to ad a 1/2 tsp of sodium sulfite before the Metol, since the metol is more soluble in an alkaline solution ;)
Thanks for additional info 🤗

@@lostlightart6064 great, thank you very much ^^
this is for photography paper .Can I try cupper plate with same chemicals .I mean :Can I make image on copper sheet with same chemicals ?
Sure it will develop any gelatine base light sensitive substance

Thanks for the tip Matthew I will make sure to put it in my notes!
