Step 3: Generate the HDR image
The next window lets you specify options for creating the HDR image.
The three photos of the Grand Canal were taken using a tripod, but we still check the Align source images option to correct for small alignment problems that may happen even with a tripod. For hand-held images, it would have been worth trying the other alignment method "By matching features".
Click on OK.
Photomatix will now merge your differently exposed photographs into a single HDR image that represents the complete tonal range captured by the photos.
Note: While the pixel values of your source images are discrete values in a finite range such as 0-255 or 0-65535, the pixel values of the HDR image are in floating point representation in order to properly represent the complete range from deep shadows to bright highlights.
