This is a set of 16 experiments with particles.

I’d describe most of them as sparks or galactic explosions.

All images are 1440 x 900, though some of them don’t use all that space.
(I figured I’d leave the creative cropping up to you. )

If you end up using these in some art I’d love to see it.

TIP: Also try inverting them

Simple enough? 

If you do use these in artwork, I’d love to see it.

I didn’t do anything to these images as far as color correction or levels adjustment, except for the two that end in “e” (edited) on the filename. It was an overcast day, so they have a touch of a blue overtone, but clean up pretty easy.
