Re: uncurve/curve comparison on Loris' website

Sorry, Mark, I wasn't ignoring this, I just didn't see it until now. And now that I see it, I can't respond to it because I have no idea what you're asking for. This thread apparently started out to be about Chris's comparison between two images with two very different pronounced color casts, and then quickly switched to be about Charles' difficulties with his tricolor gum prints. If one can judge by the quote on your post, (copied below) your request seems to come in response to something I said as part of a muddled communication between me and Loris about Charles's problem, that has since been untangled. At any rate, I'm at a complete loss as to what curve you're talking about.

Can you possibly post a screen grabber shot of the curve (photoshop curve window) that you came up with?

Best Wishes,

Sorry, the more I think about this the more it seems like watching a
dog chasing its tail. You start out with a (black) negative that
prints too contrasty because there's too much density at the top end
of the scale. To eliminate that problem, you make a colorized
negative with a lower DR. But if the color/curve takes out too much
density so you're getting tones where you don't want them, then you
decrease the dichromate to increase the contrast so that the lightest
tones won't stick. This seems like a merry-go-round that one might
never get off of.
