Russell Brown of Adobe never fails to delight and entertain. At the recent Photoshop World Conference, he demoed a free action used for producing spiraling star trails from a photograph of stationary stars against a dark sky. To obtain a copy of his action, click this link, navigate to the Star Trails Action and click the download link. When the download is complete, copy the action to a safe and memorable location on your computer, and then double-click to load the action into Photoshop’s Actions panel.
If you have a photograph of a star-filled night sky, you’re all set to use the action. If not, it’s possible to purchase a star field image from iStockPhoto.com or even to create one easily from scratch using a Filter Forge filter such as “Star Snippet.” To learn more about Filter Forge’s impressive capabilities, be sure to check out my last Workbench (PSW 280). The good folks at Filter Forge have extended a 50% discount to my audience. To receive the discount, visit my Discounts page and click through the Filter Forge link, then enter the code ud4Nswev0ySA during checkout.
Before getting started, you’ll also need to locate an image of something photographed at night in front of a deep blue or black sky, such as the image I’m using here. Now that the action is loaded and you have both a star field image and one with a starless sky, you’re all set to have fun.
