Section 3: Exposure Blending

In addition to the two-step HDR processing described in the previous pages, Photomatix Pro

also offers several single-step exposure blending methods. These will combine differently

exposed images to show detail in both shadows and highlights.

 These blending methods combine differently exposed photographs into a single image. It

uses the existing shadow and highlight detail from the source images to make a single

final ‘blended’ image with an expanded tonal range.

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

described in the previous section:

• Blending the images has the effect of reducing noise whereas HDR and tone

mapping amplify it.

• The blended image does not differ much from the source images, giving it a more

natural look.

• Exposure Blending is a simple and easy to understand process, with no or few

parameter settings.

Exposure Blending 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. The memory required for blending

exposures increases with the number of source images and bit-depth.
