Merge to 32-bit Plugin

Description

Merges bracketed photos to HDR and saves the merged image as 32-bit TIFF.

The merge to HDR includes alignment and automatic ghosting removal.

Note that the plugin does not process the 32-bit TIFF file it creates. If you want to create HDR photos from Lightroom with Photomatix HDR Tone Mapping and Exposure Fusion, please download the Photomatix Plugin for Lightroom included for free in Photomatix Pro.

Differences with Lightroom CC Merge to HDR

Lightroom includes a feature to merge to HDR, and therefore the same feature as the Merge to 32-bit Plugin, but there are differences, the main ones being:

  • The Merge to 32-bit Plugin uses different algorithms than Lightroom to merge, align and remove ghosts. In some cases, this results in smoother highlights in the merged HDR image created by the Merge to 32-bit plugin.
  • Lightroom auto-tones the merged images it creates, while it doesn't do it for images created with the Merge to 32-bit plugin.
