Exactly. HDR software takes multiple images in 8-bit color (that is, 8
bits per color) and then combines them into an image in 32-bit color.
Since our software and monitors can't display anywhere near that kind
of color depth, the HDR software then maps the 32-bit color into 8-bit
(or 16-bit) space before rendering the final image. This is tone
mapping and it's an integral part of what HDR software does.
