same but different (in a way…)
Hi-resolution picture: CLICK ON IT TO ZOOM!
The two largest rectangles have the same color average: same colors in the same proportions.
The one on the top is made of 4 layers, one color per layer, one spatial frequency per color, and the angles between the layers are “optimized” in order to get rid of moiré effects.
On the other one there’s also 4 layers, but with a unique frequency, a 45° rotation and the colors are randomly diffused.
Both are trying to “match” the average color of the background and in both paint is covering 60% of the paper.
The 1st one is almost invisible, the second appears to contain intense colors.

D65 n°3 part II starts

I’m gonna do a “lamp simulation” (a circular gradient with constant tint and varying brightness, based on the abstract model of a “perfect lamp,”) based on 11 colors: 3 times RGB with 3 levels of brightness (I dont enter into the detail of how I choosed them) and Black/White.

hi-resolution pictures of the prototype
CLICK ON THE PICTURES TO ZOOM!
Light ON/OFF, hi-resolution orthographic panorama made with Hugin.
For me, there’s not much difference between such a work (the prototype, made of laserprints on paper) and a “traditionnal painting.”
I’m really starting to think it’s just the same thing, like Richter includes amateur photography in the field of “painting.”

about to end
The central part being equalized.
Something is slightly wrong – the values are increasing where the light is intense -, but it’s still very close to what I wanted (an equalized luminance everywhere in the rectangle).

good & bad news :)
The bad news: the laser printer cannot handle large black prints, some unit of the printer makes a random glossy layer on it.
the random gloss
the (very) good news id that the luminance correction is not very angle-dependant, means that except for that random gloss, the correction works at a wide variety of viewpoints, that’s really nice.
from the left side, the gloss dissappears and the flat is still “flat.”

fake Light, 1st TW pass (in progress…)
CLICK ON THE PICTURE TO MAGNIFY IT!
The lightness will change as if there was a perfect lamp at 17 cm from the center of the figure.
The white structure appears really “transparent.”
This geometrical solution could be called the “pixel solution,” since the surface is divided in 2×2 cm squares, other solutions are possible and will be tried later on the study: concentric zones, gradients… The only color added to the grey background is Titanium White (TW), later I’ll try color, enjoy ;)

Fine-tuning of titanium-White and carbon-Black to “match’ the lightness of the grey background.
