#photochemistry — Public Fediverse posts

Hey #believeinfilm friends,

Have you ever wondered if you *really* need to heat up your C-41 chems to develop your film?

Well, you don't:

https://www.analog.cafe/r/how-to-develop-c-41-at-room-temperature-zg64

In today's guide, I explain how you can develop your colour-negative film at room temperature.

(With stand development, you don't even need to continuously agitate your film, so you can leave and come back when it's done.)

I've tested my timing across four distinct emulsions — see the article for samples :)
