For instance, if you center your composition on the North Star (Polaris), you’ll end up with concentric circle star trails. Where you point the camera in the night sky will determine the shape of the star trails in your final image. If you want star circles, you'll need to be out shooting all night and then stack the images. The fullness of the star trail stacking will be dependent upon whether you spend only a few minutes making exposures or are out shooting all night. “This helps prevent any detail from being lost in the highlight and shadow areas of a foreground area that isn’t in silhouette.” “I will often composite a foreground using HDR to blend with the final image,” says Deborah. She then stacks these images which composites the images using Statistics, in Adobe Photoshop.
Editor)ĭeborah says, “I stack stars because it gives me more flexibility with the outcome of an image.” She creates most of her star trail photographs using an exposure time of 30 seconds making a number of photographs over the course of three-quarters of an hour or so.

( Check your camera’s manual to see if your specific model incorporates this feature. The built-in interval timer can be found under the shooting menu. To simplify the process of shooting the individual shots every few minutes, Deborah sets her camera’s interval timer to make the consecutive images.

In addition to shooting multiple images and stacking them, using as low an ISO as possible will also limit noise in the final image. Another reason to use shorter exposures is to reduce the occurrence of noise that can show up in an image captured during long exposure shooting. This allows them to produce a more dramatic effect in the final image. Many photographers use a technique of shooting multiple, shorter length, time exposures and stack them during post-production, using Adobe Photoshop or another program that will allow you to stack multiple files into one photograph. We spoke with two photographers-Deborah Sandidge and Diana Robinson-to find out their techniques and tips for great star trail images. A star trail occurs when you photograph the stars over a long period of time, from minutes to hours. Photographing Star Trails is a unique way to capture the night sky in a photograph.
