Updated in Lightroom Classic CC 7.4 (June 2018 release)
Lightroom Classic lets you merge multiple exposure-bracketed images into a single HDR image.
How many photos are optimum for an HDR photo merge?
Merge photos to create HDRs
-
-
Select Photo > Photo Merge > HDR or press Ctrl+H.
-
In the HDR Merge Preview dialog, deselect the Auto Align and Auto Tone options, if necessary.
- Auto Tone: Provides a good starting point for an evenly-toned merged image
- Auto Align: Useful if the images being merged have slight movement from shot to shot. Enable this option if the images were shot using a handheld camera. Enabling this option may not be necessary if the images were shot using a tripod.
You can preview the effects of these settings right within the dialog box.
-
Sometimes, after the exposure-bracketed images are merged, some areas in the HDR image may appear unnaturally semi-transparent. Select one of the following deghosting option in the HDR Merge Preview dialog box to correct these anomalies: None, Low, Medium, or High. Try Low deghosting first to obtain a clean merged image. Try higher settings if necessary. Avoid using if your preview is free of ghosting artifacts.
- Low: Cures little or minor movement between frames
- Medium: Cures considerable movement between frames
- High: Cures high movement between frames
You can preview the effect of these settings right within the dialog box. If necessary, choose to view the deghost overlay.
-
To group the exposure-bracketed images and the HDR image in to a stack (after the images are merged), select the Create Stack option. The merged HDR image will be displayed at the top of the stack.
-
Click Merge to create the HDR image (.dng). Lightroom Classic creates the image and displays it in your catalog.
