Here's a quick and easy way to create star trails in Photoshop CS5! Click on the fly-out menu in the Actions palette and load the action - Star Trails Rotation. Choose a photo of stars that you'd like to rotate to make star trails. Start the action, and watch the magic happen!
I used a single photo of stars that I shot on Florida's east coast for the star trail rotation action. For the foreground, I chose a castle that I photographed in Europe, and toned it blue. To tone your image, use a Hue Saturation adjustment layer and check Colorize. Move the hue and saturation sliders to create the look you like. Composited together, the two images tell a dramatic and interesting story. Have fun in Photoshop!
