Star Trails Over Yosemite Falls, Yosemite National Park

Star Trails Over Yosemite Falls, Yosemite National Park.  Photographing Star Trails is a unique way to capture the night sky. A star trail occurs when you photograph the stars over a long period of time, from minutes to hours. Many photographers use a technique of shooting multiple, shorter length, time exposures and stack them during post-production. Adobe Photoshop is one such program. This allows them to produce a more dramatic effect 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. In addition to shooting multiple images and stacking them, using as low an ISO as possible will also limit noise in the final image.
To simplify the process of shooting the individual shots every few minutes, I used a kitchen timer set at 4 minute intervals. “I stack stars because it gives me more flexibility with the outcome of an image.I shot 25 photos over a 4 hour period. “I will often composite a foreground using HDR to blend with the final image,” “This helps prevent any detail from being lost in the highlight and shadow areas of a foreground area that isn’t in silhouette.” If you want star circles, you’ll need to be out shooting all night and then stack the images.

Composition
Where you point the camera in the night sky will determine the shape of the star trails in your final image. For instance, if you center your composition on the North Star (Polaris), you’ll end up with concentric circle star trails. Other compositions can produce arc shaped star trails. Many of the photographs that are taken of star trails are captured using wide-angle lenses, so interesting “terrestrial” foreground elements can be incorporated into the composition. Some of these foreground subjects will make ideal silhouettes, while others would benefit from a little exposure (natural or man-made).  https://www.youtube.com/watch?v=OM1-MlCrfkg
