    In "the old days" (not so long ago actually) I worked in a commercial darkroom. We used a lot of photo-opaque and a lot of lith to get the effects used before digital appeared on the scene, so don't be feeling that that sort of idea is somehow less analogue ! ;o)

    Isn't ortho sensitive to both blue and green?

    True, this work is not less analogue.

    Perhaps it's just my own way of working, but I am really proud of a picture when I have not much to tweak when printing. I try to stay with contrast/grade exposition and cropping. Sometimes I do some dodge and burn, but not that often, I don't like it.

    I feel that using film gives me more freedom, and maybe - or paradoxally - less work to do on the picture. I try to get the most interesting negs possible and if they are not, I do what I can but I never do a lot of manipulations.

    Maybe I can explain this by working in a small not convenient darkroom (my bathroom)!

    This being said, I will certainely try all the differents ways you guys proposed me, and stick with the on that give me what I want directly on the negative.

    Thanks a lot,

    Kris

    A sharp cutting blue separation filter, like a 47B, will pretty much eliminate the reds as well as the greens. You can probably get about the same effect with panchromatic film as ortho with this kind of filter. One warning: skin tones get pasty.

    Chazzy - you are correct. From Ilford's own info:

    "ILFORD ORTHO Plus black and white copy film....The blue and green sensitivity enables the film to be handled in red safelight and allows processing by inspection."

    Jim is thinking of "color blind" emulsions which are not sensitive to green or red.

    Best,

    C
