Merge images to HDR

Use the Merge To HDR command to combine multiple images (with different exposures) of the same image or scene,
capturing the dynamic range of a scene in a single HDR image. You can choose to save the merged image as a 32-bpc
HDR image.

Note: It’s also possible to use the Merge To HDR command to save the merged image as an 8- or 16-bpc image. However,
only a 32-bpc image can store all the HDR image data; 8- and 16-bpc images will be clipped.

For information on taking photos to merge into HDR images, see Take photos for merging to HDR, below.
