    hey guys, i was wandering if i had a colour film developed, would i be able to take into a black and white darkroom and use the enlargers there etc... to process it in black and white?

    if so does it come up as shard etc...?

    thanks!

    if the pics have not too much red, it would work but you won't get real white tones, they would be a bit gray.

    It works... but your pics will be lacking in contrast slightly compared to normal b+w film - think this is due to the coloured base layer you get on most colour negs (the bit that gives the characteristic orange colour to Kodak negs, for example). Use a high contrast paper to compensate.

    There might be an issue with increased grain size, but I'm not 100% sure on that. Use it to your advantage for atmospheric, grainy shots if there is!

    Can others edit my Photos:
    Photos NOT OK to edit
    My experience is that they tend to print very low contrast, and the grain is more noticable in BW. I don't think it's actually bigger, but somehow the color hides it better.

    I've printed a handful of color pics on bw. Some were easy to print, usually just adding a 3 or 3.5 filter and some I couldn't get to work for anything. Kodak makes a special paper for printing color on black & white called Panalure, but I never tried it, it seems like it was pretty expensive and had to be processed in the dark iirc.

    It'd seem to me that you could apply a filter to bring the contrast back out of the color. Might have to play around with it a bit.

    Colour neg film has an amber base. Normal B/W papers are only sensitive in the blue region so you need long exposures and you get low contrast.
    Kodak do a panchromatic photopaper called Panalure for doing this job. But you need to handle it in total darkness just like film. Works well, though.
