Making Grey

Principles of color photography.


Selective and nonselective neutrals– a foundation concept in the technology of color photography. The illustration that we have many paths to grey, none of them is the perfect path. For any decision about a colorant (dye or pigment) we must consider more than making a neutral, even a set of dyes making a neutral results in different color volume. This is the why a film looks different: the relationships among the real color and the created color. Industry chooses the colors that they can sell. Old texts, as well as the experiments, remain useful, valid today. They form the foundation. Those equations are accurate — math has a way of doing that.

The means to the solution. The tools of presenting or testing, examining the experiments have changed drastically since the foundation years. We can readily present to others results they couldn’t imagine. That has changed the learning, not the theory.

we can easily compare gamuts using at hand Apple tools. this color cube is what a set of balanced Kodak dyes from dye transfer (1985) covers compared to the background cube of an HP Z printer on glossy baryta paper from 2015.

Clearly, implementation of the theory has advanced.

his main image goal is sharp detail... afterthoughts are size, and color, but based upon ? naive perception of possibles. he limits his subjects...taking the well worn mannerisms.

Pathological lying or lying compulsively can also be a symptom of antisocial personality disorder or narcissistic personality disorder. People with these personality disorders may lie to gain sympathy or social status, or to preserve a false sense of self.Nov 14, 2022

Why the claim to the unknown, the name-drop, the value assertions? And, how do they work so long among so many?

Claim to X because deep durable knowledge of X is gone.
Perception of expertise goes across entirety of community.
Why DWiley creates fiction of Eliot Porter’s machine shop skill — must be used to make dye transfers. What Eliot had was math / chemistry skill. He wasn't a machinist during the war; he was a clerk, a scheduler. His darkroom, and office showed his wood-shop skills. Desk. Enlarger stand. [ ]

he wants you to like him. he wants to control you; think him the expert; believe he has the answer. He craves being the head of the table.
But, like all bullies, he only has fun by diminishing you.
--thats where amateurs go to impress other amateurs
need to control, to belong, prove worth through mastery
early, limited success , derive meaning of life not found in real life.

My still bigger Durst L184 color enlarger and huge custom 8X10 additive color enlarger are in a different room, necessarily with a much higher ceiling. So I'm quite familiar with adaptations of Durst heads and columns.

Nice looking. That's the problem. I has "steal me" written all over it.
do cost quite a bit more for decent quality. I bought mid-level LED panels for my own use - about $700 for the pair.
