the tonal values of the images are linear relative to the values of light captured. Please note that

the terminology linear may be used with a different meaning depending on the RAW converter

(in Adobe Camera RAW, for instance, linear is relative to the Adobe RGB color space and not to

the values of light).

Generate HDR settings when the source images are RAW files:

The Generate HDR - Options window will display with additional options:

It is important to note that the selected color space is used for the color primaries only, and not

for the tone reproduction curve. Since the HDR image values are in linear space, they do not

have a tone curve. The tone curve of the profile associated with the image will only be applied

during the tone mapping step, and not to the HDR image itself

Once you are satisfied with the settings of the Generate HDR - Options window, click OK to

create the 32-bit HDR image.

A progress bar will display in the Generate HDR - Options window. Once the HDR is

generated, the HDR image and the HDR Viewer window will display on-screen.

By default, Photomatix will use the As Shot

White Balance (read from the EXIF

metadata) when converting the RAW data to

HDR. You can adjust the White Balance by

selecting a pre-defined white balance from

the drop-down menu, or by specifying the

color temperature in Kelvin. A preview lets

you see the effect of the change on the

source image.

The RAW data is in a color space specific to

the camera. Photomatix will convert the data

into a standardized color space (by default

Adobe RGB). You can, however, select

sRGB or ProPhoto RGB instead.
