    Why some of the gallery bw images have blue color cast , some others have brown color cast ?
    I dont like blue ones , Kodak D76 , HC 110 , Tri X have a brown cast .
    Why is that ?

    Some posters here may scan in colour in order to faithfully recreate the image tones of their prints.

    And some who post negative scans may cheat a bit in order to recreate the image tone they hope to get in their prints.

    Some blue ones are cyanotypes and are really blue!

    Toners will color them, my copper toned prints really are a brick red, my warmtone selenium goes a nice purple. If you convert them to monochrome then you aren't really showing what the print looks like.

    This is an interesting observation. I sense a shift to blue in the way my scans are on the monitor, yet I have a little Kodak dye-sub printer that produces tones that are correct (to my eye). I don't know anything about PS, or I guess something could be done about it. Or not.

    Because a lot of us do not have our monitors calibrated?

    And B&W prints can be cool, neutral, warm or any tone the photographer wants them to be if s/he has the ability to get those colors.

    I scan prints if I can. And if I scan negs and reverse them, I try to make them the color the prints will eventually be -- and my carbon prints can be any color I want them to be...just a matter of picking which watercolors to use in making the "glop" (pigmented gelatin and sugar). Presently I am using lampblack and a little burnt sienna.

    Every monitor is calibrated different. You should see them on my work computers... horrendous!

    (I'm talking about the color shifts of my own work)

    That's why only a print or chrome on the light table/screen really counts :smile:

    Umut - I guess that's one of the problems with digital photography.

    If we could see all the prints first hand, we'd be able to by-pass all the issues with scanning and monitor calibration. But alas, this is APUG and such topics are forbidden...

    Like Vatya says it's the big differences in monitors, and as Vaughan says we don't all calibrate them.

    This is a neutral step wedge so if it has a colour cast then your monitor is way off :D

    I scan my negs in colour because I can't figure out how to do a proper B&W scan with SilverScan. I don't photoshop them though.
