Is it possible to generate 'random' pixels in Photoshop?
I want to generate an area of random pixels in Photoshop. By random, I mean the 24-bit RGB values of the pixels vary uniformly over the range
0xffffff. The opacity should not vary. I've experimented with the Add Noise filter, but I can't get anything like the desired effect. Is this possible with Photoshop?
Photoshop isn't really meant for this kind of randomness as it is meant for control.
But here's a workaround without any scripting:
Select the Pencil Tool
Go into the brush options
Select 'Color Dynamics'
Crank up Foreground/Background Jitter, Hue Jitter, Saturation Jitter, and Brightness Jitter
Change the background/foreground color so it isn't just black and white.
This will generate some random values. It won't be 100% random, but you can play around with it.
