The Capture One Plugin included in Photomatix Pro lets you select a set of bracketed photos in Capture One, merge it to HDR in Photomatix Pro and adjust the look of the HDR image before saving it back to your Capture One catalog or session.
You can choose from a large range of HDR styles and presets, from Realistic to Artistic, to adjust the HDR image to your liking. You can also choose a simple exposure fusion process using the 'Natural' preset, and then further adjust the look with Capture One's High Dynamic Range tool.
The plugin is compatible with Capture One version 12 and higher.
If Capture One is installed on your computer, the Plugin should be automatically installed when you run the installer.
