2.1.2 Comments on the generated HDR image

In the companion “HDR viewer” window, the small image area at the top displays a zoomed-in

section of the properly exposed HDR image at the current pointer location.

The generated 32-bit HDR image is in an unprocessed state, which means that the large range

of highlight and shadow details contained in the HDR image cannot be properly displayed on

screen at this stage. An unprocessed HDR image is, in a way, similar to a film negative or the

RAW file of a digital camera. The image needs further processing, called Tone Mapping, for

display or printing.



Saving the 32-bit HDR image at this point will allow you to apply different Tone Mapping

settings to the HDR source image without repeatedly following the “Generate HDR” procedure.

Photomatix Pro saves the name of the color profile in the header of an HDR image saved in the

Radiance (.hdr) format. This means you will not have to re-assign the color profile, provided the

HDR image file have been saved as Radiance and the color profile is either sRGB, Adobe RGB

or ProPhoto RGB

. However, the color profile information of the source images will not be

preserved if the HDR image has been saved in the OpenEXR format.



Photomatix Pro allows you to create a 32-bit HDR image from a single RAW file.

To do this, open one RAW file using File >Open, and Photomatix will convert it into a

pseudo-HDR image. It is important to note, though, that an image created with a single

RAW file cannot really be considered High Dynamic Range. The important characteristic

of this pseudo-HDR image is that it is unprocessed. Its dynamic range is not much larger

than the range of an already converted file.
