Decided to have a mess around with filters and brushes in Photoshop. Here is what I created.
For this image I think I used Filter > Noise > Median. I also used Filter > Render > Lens Flare. Unfortunately I didn’t save this one so I can’t make any screen shots.
For the image above I took screen shots to help me remember how I made it.
Here are some of the others I created. I really like bright colours 😀
