Re: acorns(!)

I agree with Marek; this goes back to what I said about an earlier post of Loris's, that the eye and mind together "read" a wide variety of color palettes as "realistic color" as long as the tonal relationships are proportionally accurate.

Loris, thanks for your answers to my questions, which support my earlier thought that I don't believe this is stain (maybe even in the specular highlight on top of the acorn) I think it's just the same thing we were talking about before, that the graininess of the paper negative scatters the color into discrete dots rather than the continuous mixed color that you'd get by overlaying continuous gum layers over each other. I agree with Marek that the pointillistic effect is very attractive and could be exploited to good effect, but as long as you use the negatives you use, you're always going to get this color scattering in all but the darkest areas, where it is obscured because the pigment is laid down densely enough in all the layers so that the spaces between the dots don't show. There's absolutely nothing wrong with this pointillistic effect, but it seems to me it would make it more difficult to achieve your other goal of achieving a perfect tonal scale in perfect neutral greys this way. The two effects seem, maybe not mutually exclusive, but certainly not very mutually compatible either. Just a thought.

WHat a beautiful print. While the colors are not photo-realistic, they are absolutely convincing. What I mean is that if you were to post the original photo we would say that your interpretation is so different. Well, I think that is the point to print a "different print". I just adore the background that has a mix of random pigmentation

It seems that your stripe pattern is only evident in the magenta negative. It is quite distractive from the randomness of the background. I wonder why that is the case.
It seems that you have arrived at a very balanced combination of pigment ratioes, gum thickness and exposure/development.
Do yo need any more encouragement?
Hope to see some more work
