Batch merge bracketed stacks to HDR in Lightroom with a preset you select from a large range of styles.
The HDR Batch Plugin works in Lightroom 6 and Lightroom Classic CC.
Compatibility:
Windows 10 / Windows 11
macOS 10.11 through macOS 26 Tahoe - Apple silicon chip & Intel processor
Once you've installed the HDR Batch plugin, follow these steps to access and use it:
Note: If your bracketed sets all have the same number of exposures, it isn't necessary to group the brackets into Stacks. Instead just select all of the photos (then on the plugin's window, you'll choose the 2nd option in the Input section).
(Alternatively, choose File > Plug-in Extras > Photomatix Batch > Batch with Photomatix HDR)
See more details in the Using the Photomatix HDR Batch Plugin for Lightroom tutorial.
