Section 3: Exposure Fusion

Exposure Fusion is the process of combining your photos under multiple exposures into one

image with details in both shadows and highlights. The resulting image with increased dynamic

range is achieved in one step with Exposure Fusion, whereas HDR Tone Mapping requires two

steps. Exposure Fusion was known as Exposure Blending in prior versions of Photomatix Pro.

Exposure Fusion offers several advantages over the HDR and Tone Mapping workflow

described in the previous section:



Fusing the images has the effect of reducing noise whereas HDR and tone mapping

may amplify it.



The fused image does not differ much from the source images, giving it a more natural

look.



Exposure Fusion is a simple and easy-to-understand process, with no or few parameter

settings.

On the other hand, Exposure Fusion may not always work well when the dynamic range of the

scene is high. This can result in a lack of local contrast and a “flat” look. Also, the memory

required for fusing exposures increases with the number of source images and their bit-depth,

whereas the memory required for Tone Mapping depends only on the width and height of the

image.



When your source images are RAW files, you should convert them in your favorite

RAW converter before processing them with Exposure Fusion in Photomatix. This is

easy to do if you have Lightroom by using the Lightroom Export Plug-in to Photomatix

Pro as detailed in section 5.
