No, for each of the 256 squares I increased the green by using a mask. Can't remember how exactly.

Wow, how much time did you spend to finish this? Am I right, that after you copy it 256 times, you have to edit all of the square's colors? Because I think it's impossible to finish it…or is there another way? I tried to make one… I think you should make a tutorial of how to make it…

I believe I made it using Photoshop. I started off by making one of the small squares and then copying it 256 tims and adding one level of green for each square, somehow.

What software did you used?

Wow! Great work! I counted how many pixels there are in one of the boxes (which there are 256*256 colors (since one row of one box consists of 256 colors), or 65536 colors). There are 256 boxes, so the total number of colors there are 65536*256, which equals 16777216 colors. Amazing! How did you make it? I once tried with Paint, but I failed, cause it takes too much time…To the mathematical challenge: There are 16777216! ways to arrange the colors. So, the possibility is 1/16777216! to get the random image.

If you re-compress it with PNGOUT, you can shave another 6% off the size… and then compress that with WinRAR, it smashes it down to a teeny tiny 1.34kb.That's just 1/36,680th of the uncompressed [bitmap] size!

The number of combinations there are is 16777216_P_16777216 = 16777216! / (16777216-16777216)! = 16777216!, so yes, 1/16777216! is the probability of getting the ordered example (since the randomized image has no repeated colors)stirling's approximation of 16777216! is: sqrt(2 pi 16777216) (16777216/e)^16777216(using the help of logarithms to approximate the second term)which is approximately 10267 * (8 * 10^113924433)which is 82136 * 10^113924433which is 8.2136 * 10^113924437so the probability is (approximately):1/(8.2 * 10^113924437)which, i must say, is incredibly tiny (the smallest amount time possible, planck time, is 1/(5.39 * 10^44) )

If you open the randomized picture in photoshop and use a gaussian blur at maximum blur you get exacly 50% black.Later.

Hey there. Some time ago, I started a little project called allRGB. So far I have posted 11 creations myself (see entries), and I was wondering if you would be willing to contribute. Cheers!
