New book...A DEEPER DARKER TRUTH
Started by Jack White, Oct 16 2009 04:41 PM
Defense by Jack, Bernice, Adele--and the airbrushed Peter, together with the brazen know-nothing "Colby"--what crude censorship
I found this excellent passage from Jack
BEGIN
Photography is based on a very simple principle.
1. A white base material, usually paper, has a "silver" emulsion spread evenly on its surface
to a precise DEPTH.
2. Exposure to light PENETRATES the depth of the emulsion in proportion to the intensity of the
light falling on it.
3. The photo paper is "developed", removing LAYERS of emulsion in proportion to the amount
of the light exposure.
4. The print is VIEWED by eyes viewing the print in LIGHT WHICH PENETRATES THE THICKNESS
OF THE "SILVER" ON THE PAPER, STRIKING THE PAPER, AND REFLECTING BACK TO THE EYES
THE THICKNESS OF THE VARIOUS LAYERS OF EMULSION.
Anyone who does not understand this LAYERING of tones in a photography cannot possibly
hope to understand Wilson's work.
The eye can only perceive about 20 shades of gray. The computer can easily perceive 256
shades of gray (and even many times that amount).

Hence you take a computer when you're sniffing for drugs, bombs, cadavers, because you're mortal
Tom didn't go from drawing Marvel Comics--he went from analyzing steel--for the guy in Network who foghorned Howard Beale
It's eerie seeing Peter referred to
Colby or "Colby" seems the least interesting man in the world
"I seldom read books, but when I don't, I pan them. Stay ignorant, My Friend."
