Original photo of this American Oystercatcher was taken in diffuse light which gave a featureless light sky background. PP began with Fractalius, rendered with 100 Glow effect to a dark background. The sky was then black but still no features. I masked the bird and water, then added a black layer, then added some Gaussian noise to sprinkle lots of white tiny stars, actually way too many. Then did a levels adjust to eliminate many of the stars. Stars were too sharp so I used the Blur tool to fix that. Finally, used the brush tool at 25% opacity to dot in a few larger diffuse stars. Whew!
