Camera Bracket settings
Updated in Lightroom Classic CC 7.4 (June 2018 release)
Lightroom Classic lets you merge multiple exposure-bracketed images into a single HDR image.
Read these guidance notes and tips by Rikk Flohr (Software Quality Engineer for Lightroom ecosystem of apps, Adobe).
HDR photos are used to capture scenes having a large dynamic range. However, using more number of photos can lead to unwanted artifacts from poor alignment or ghosting. For optimal HDR merge, the aim is to capture photos in a manner that each part of the scene is well-exposed, that is neither blown-out nor under-exposed in at least one of the photos.
Use the following guidelines to identify how many photos work best for your case:
Camera Bracket settings |
Optimum number of exposures for merging photos to HDR |
---|---|
-1.5 to +1.5 |
2 |
-3.0 to +3.0 |
3 |
-4.5 to +4.5 |
4 |
-6.0 to +6.0 |
5 |
Cmd/Ctrl-click the images in Lightroom Classic to select them.
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.
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.
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.
The Create Stack options has been introduced in Lightroom Classic CC 7.4 (April 2018 release)
Click Merge to create the HDR image (.dng). Lightroom Classic creates the image and displays it in your catalog.
