Exposure Blending
Introduction
Photomatix lets you combine images with different exposures using the Average method or one of the Highlights & Shadows methods. Those latter methods perform a process known as Exposure Blending
The Highlights & Shadows methods make use of advanced algorithms to select and blend together the details available in the different exposures.
The Average method combines the images using the same average formula everywhere, regardless of whether the computed pixels are in a dark or bright area. This is why averaging can not produce the dynamic range extension that you can get with one of the Highlights & Shadows Exposure Blending methods. However, averaging has the effect of reducing noise and is often used for a process called Image Stacking.
To use the Exposure Blending functions of Photomatix Pro:
1. On the Process menu, click on the Generate item.
2. Click on the Browse button to go to the location of your differently exposed images and select them using the SHIFT+Arrow keys or your mouse and CTRL key (command key on Mac). Then click on the OK button.
3. The window lists the source images that will be blended. If the images are not aligned (e.g. shot without the aid of a tripod), check the option Align images. Then click on the OK button.
To blend exposures automatically and/or process large files, please refer to the section Batch Processing.
