    I don't understand Rodinol...

    When I develop Adox, the pre-dev wash comes out deep blue and the developer comes out red.

    When I develop Agfa Green x-ray, the wash comes out pink and the developer comes out blue.

    The Agfa film is pink before exposure and blue after it's developed...

    I'm sure it's doing it just to annoy me!

    This will seem counter-intuitive, but after a post-fixing rinse put it back into any developer, agitate well and wash. The tint left on the film should be gone.

    tmax - the developer looks like grape rush when you dump it out


    I told my kid I develop film in grape crush and showed he when I dumped it out

    she didn't buy it..but she knew to be wary of what I said by age 3

    I think that's a Kodak thing. The Ektar and portra I have done c-41 all come out with the same color from the presoak.

    Mostly these are the sensitizing dyes. It's how you turn an orthochromatic emulsion into a panchromatic emulsion.

    If you do a prewash, it will carry a bunch of sensitizing dye with it when you pour it out. And you haven't even started to develop the film yet. When I do this with TMY-2, I get purple. At the end of processing the film is usually slightly purple-pink.

    The color is basically meaningless. If you don't like your film color when you're done, give the film a few minutes in sunlight. The UV will generally kill off the color for you. But it's not necessary. You can print right through it in the darkroom (has no effect on the print). Similarly, you can scan right through it.

    So it doesn't affect variable contrast paper?

    When I called Kodak and asked that very question, they said no.

    Seems to me the only potential effect on VC paper would be if the color was a variation of magenta.

    Yes it does... The contrast layer on MG is blue sensitive, so this allows more blue... (Magenta has blue in it, so adding it cuts green, but adds blue...)

    X-ray prints contrasty for many users of MG due to blue base...

    Early Tmax RF had a built in contrast filter for Kodak VC papers for it's screwy grade 2 3/4(ish) required filter to print normal... (The Kodak rep told me so in person when he came to the pro lab and I asked about it... ;-)
