Thanks
When I look at the above mentioned image without my calibration loaded
in a not color aware browser I can see the numbers down to 5-4. When I
load the calibration curve, still viewing in the same viewer, I get
all numbers down to 1. When I enable relative colormetric in a color
aware viewer and with my calibration loaded I'm back to five.
Perceptual give me 2-1 on the above image.
It was wrong what I wrote about the matrix profile in my last e-mail.
The matrix profile gives me 5.
I created a collections with screenshoots, but I don't think they can
view the real truth on any other monitors than mine.
