To work with certain Photoshop features, you can convert a 32-bpc image to a 16-bpc or an 8-bpc image. Do a Save
As and convert a copy of the image file to preserve the original.
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.
