color developer – Koraks tinkers

Who’s afraid of cyan, yellow and magenta? Using color C41 and RA4 chemistry at home

I regularly speak to people who would like to start doing color development (film or prints) at home. Often, they’re shunned by the prospect of having to deal with color chemistry in a home darkroom setting. Please don’t let it stop you, though. Doing color work in a home darkroom is really pretty easy. And it doesn’t have to be very expensive, either.

Between the lines – The importance of interlayers in RA4 color paper

‘Today I learned’…a lot, in fact! More than enough to fill a couple of blogs, but let’s start with this one. Did you know that color paper has layers that you can’t see, that are actually designed to be invisible, but that play a huge role in the visual aspects of the paper and the images on it? Well, now you do! They’re the interlayers, and they are quite essential, as it turns out. I’ll try to explain.

Color me purple – Some color developer formulas including C41 and RA4

Despite the modest resurgence of interest in film photography, supply issues remain a concern. This is nothing new; a few years ago, I already worried about this and figured that I wanted to expand my options when it came to in particular color chemistry for C41 negative development and RA4 printing. I started collecting formulas I found online, purchased the necessary chemistry and mixed quite a bit of (mostly) developers myself. Now seems a good time to share my findings with you. If anything, it might be convenient to have some key formulas in one place.
