i've done the color-as-bw trick, and it works, but everything looks like garbage, more than i would normally expect.
baking soda seems like a poor choice, i've heard borax and soda ash (carbonate rather than bicarbonate) more commonly recommended. maybe it would work in a pinch but baking soda is significantly less basic and might produce gas during the reaction which seems problematic.
but sea water for fixer, that's interesting, never considered that one. is it really ionic enough? i guess i could boil down a reduction
edit: chatgpt seems to think i'd need to concentrate it to saturation and at that point i might as well just use table salt. do you have any experience with this? how does the negative hold up over time?
- actionfromafar 3y agoBest is to soak the film in the sea itself for hours, so you get an exchange of fresh ions. It’s not the table salt, NaCl, that (probably??) does the fixing, but other trace ions that does it. So super market table salt may or may not work. I put a picture in a saturated solution of cheap horse salt for 24 hours in a soda bottle. Worked fine! Re baking soda, it stops fizzling after a minute, and you just have to compensate with more baking soda and/or longer development time. Re C22 film, it can be developed in C41 chemicals if at room temperature. Increase development time to … more.
