Reducing Noise with Star Stacking

Star stacking is one of the best ways to reduce noise in nighttime photographs. By blending multiple frames together you can average out random noise to create cleaner, sharper images—all while making the stars appear as points of light rather than streaks.

Capturing a star-stack sequence is a relatively simple process, and doesn’t require any special equipment—you just have to capture multiple frames of the same scene with the same settings. The challenge is blending those exposures together later, and lining up the moving stars. Fortunately programs such as Starry Landscape Stacker and Sequator make that task relatively simple.

In this presentation Michael Frye will explain how star-stacking works. He’ll take you step-by-step through the whole process, from capturing the images in the field to blending them together later. Best of all, you’ll learn how this technique can open up new creative avenues that wouldn’t be possible with single exposures.
