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 0x000000 - 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:

  1. Select the Pencil Tool

  2. Go into the brush options

  3. Select 'Color Dynamics'

  4. Crank up Foreground/Background Jitter, Hue Jitter, Saturation Jitter, and Brightness Jitter

  5. 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.
