What happens if I use JPEG or 8/16-bit TIFF input images?

in

JPEG or TIFF can be used as source images for "Merge to HDR" function.

You can also use HDR Expose to enhance single 8-bit JPEG or 8/16-bit TIFF photographs with great results. Because HDR Expose uses the Beyond RGB™ color model, image editing and enhancement become a quick and powerful process. HDR Expose operations work on any image.
