Merging Images to HDR

The Merge To HDR command () allows you to combine multiple images (of different exposures) of the same image or scene, or a bracketed exposure. HDR (High Dynamic Range) creates 32-bit high-end digital quality images. The Merge To HDR command takes the best elements of each photograph and combines them to create a single HDR image with more dynamic range than possible with a single digital image. Since several photos will be combined to create a single image, it's important to place the camera on a tripod (so it won't move), and then take enough photographs (3 minimum) at different exposures to capture all the dynamic range of the scene.
