Adding to the uncertainty, another key figure departed xAI just 24 hours after Ghori. Co-founder Greg Yang stepped down to focus on his health after contracting Lyme disease. …..
This latest departure follows the loss of co-founders Igor Babuschkin and Christian Szegedy, who Bloomberg noted left the business last year. With the team shrinking so quickly, Musk may soon have to put a robot in charge. Given the mounting legal headaches—from questionable construction permits to the recent scandal involving Grok’s image tools—it wouldn’t be a surprise if no one wants to take on the challenge ahead.
“Intelligent individuals learn from every thing and every one; average people, from their experiences. The stupid already have all the answers.” ― Socrates
one of the optiquals… using light for means, by means other than image-formed pattern. Sometimes the H&D curve is more bendable than others. More details follow…
:the mysterious Q is called upon from the shadows as explanation for almost any effect. What does it explain? Do you use it… that other light; that other exposure summation. Think weeding … sometimes it makes tea.
Photography is a simplified form of drawing; let the thing draw itself.. the law, rather, the principle of exposure holds for most of the time. Like all real things the exposure rule varies. This variance provides confusion or useful options, even if you don’t know the names of the various effects. Reject before using is a rule of turds. Well known, widely influential resources gain stature by passing along their approach; their dictionary, complete with conceptual restrictions takes hold.
if not controlled, at least understood — edge of distinction —
More importantly, how can you use exposure effects in control of the image. How to manage the different points of the curves. Tone-bending, by using effects discovered and refined by early photographers building out the field of light sensitive surfaces.
Flash and Burn characteristics of the enlarger. The slide-set introduces the concepts of controlling some of the HD shape by means of altering single contrast emulsions, such as films. All dye labs had full understanding of these principles. Some of the information carried over into the fixed grade BW darkrooms.

Flare up. The other words, effects found upon deeper reading into the the literature of exposing silver materials. If you were a designer of systems, or an extremely inventive user, these terms, often named after their initial discoverer, will take you along the full path of the characteristic curve; enough so, that you could begin to design exposure making and measuring systems.

Using means knowing the difference between a silver contact and silver projected image in common darkroom printing. Dye-transfer is BW made complex by the number of steps; permutations seemingly beyond understanding. We learned the difference between silver testing and color, dye testing. The AIM, targets used had effects that could confuse ones initial learning — without luck, or well directed starting information it could seem a fools burden… pushing snowballs up a volcano.
Become alert to difference in response between instrument reading and material action: measurement may not predict fully, accurately. What you measure may not be what you get — refine, or re-define. Dyes aren’t silver; this meant that what we tested changed by stage of the process; was it silver, or dye stage material.
