Hi All

Hope someone can help. I have decided to get back into film processing and have downloaded information on homemade developers using coffee, ascorbic acid and soda crystals, there is just one problem, I am using colour film that I understand it will develop as black and white, my question is, when taking the photographs, do I treat the film as black and white, using filters, or treat it as the colour film that it is.

Any help would be appreciated.

hi stivi
i use the same coffee developer and like you,
use it with color film ( both c41+e6 )
i have used rgb filters and made trichromes
with the negatives before so i am guessing
you won't have an problems using b/w filters.
but i would shoot a test roll just to make sure
have fun!

If I were you, I'd shoot the film as if it were colour.

Hi - thanks for the info. I will give both a go, this is all new to me, never knew you could use household stuff for developing films.

Check the Coffee Developers Group on APUG. I have posted my stand development method that works for me every time using a variety of B&W films of varying ASA.

Caffenol is great. I have also used it to develop prints. The best part is putting the print in the fix. Smells like tuna sandwiches.

Trouble is the coffee developer works out more expensive than off the shelf developers and results can vary greatly.........

your welcome.

trichromes are when you take panchromatic film and color strip a subject / make 3 exposures
each, with RGB filters ( 1 each filter )
and then you combine those filtered negatives to make a color image
like these that were done before world war 1

i don't do color printing so i have to combine them using modern technology, still lots of fun !

goodluck !
