Lightroom desktop lets you easily merge multiple exposure-bracketed photos into a single HDR
You can see a quick preview of the resulting HDR, panorama, and HDR panorama created and make further adjustments to it before the final merged photo is generated.
-
Command-click (macOS) or Control-click (Windows) to select multiple exposure bracketed source photos when in Photo Grid (
) view or Square Grid (
) view, or from the filmstrip appearing at the bottom when in Detail (
) view.
Photos of the same objects at different exposure levels ("-1" and "+1" images) -
Do any of the following to merge your selected photos into a single HDR photo:
- Go to Photo > Photo Merge > HDR.
- Control-click (macOS) or Right-click (Windows) your selection of photos and then select Photo Merge > HDR from the options displayed.
Select multiple exposure bracketed photos to merge into an HDR. -
In the HDR Merge preview dialog, you can choose to enable/disable the Auto Align and Auto Settings options and adjust the Deghosting Amount if necessary.
- 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.
- Auto Settings: Provides a good starting point for an evenly-toned merged image. You can preview the effects of these settings in the preview dialog.
- Deghost Amount: Some areas in the merged HDR photo may appear unnaturally semi-transparent. Adjust the Deghost Amount slider to - None, Low, Medium, or High, to correct these anomalies. Initially, try low
deghosting to obtain a clean merged image and move to higher settings based on the generated preview.
Low: Cures little or minor movement between frames
Medium: Cures considerable movement between frames
High: Cures high movement between framesCheck Show Deghost Overlay or press the O key on your keyboard to see where
deghost corrections will be applied on the merged HDR photo.
Choose to apply Auto Align, Auto Settings, and adjust the Deghost Amount in the HDR Merge preview dialog. -
Once you've finished making your choices, click Merge to create the HDR image. By default, a stack containing your source files and the merged photo is created, with the merged HDR photo visible on the top of the stack. A suffix HDR.dng is appended to the filename of the merged photo.
The resulting merged HDR photo. The merged photo is stacked with the source files.
You can apply all Edit panel settings to the merged HDR photo just as you would apply them to individual photos.

Do any of the following to merge your selected photos into a single HDR photo:
- Go to Photo > Photo Merge > Panorama.
- Control-click (macOS) or Right-click (Windows) your selection of photos and then select Photo Merge > Panorama from the options displayed.
Select a series of standard exposure photos to merge into a panorama. -
In the Panorama Merge Preview dialog, choose a layout projection:
- Spherical: Aligns and transforms the images as if they were mapped to the inside of a sphere. This projection mode is great for really wide or multirow panoramas.
- Perspective: Projects the panorama as if it were mapped to a flat surface. Since this mode keeps straight lines straight, it is great for architectural photography. Really wide panoramas may not work well with this mode due to excessive distortion near the edges of the resulting panorama.
- Cylindrical: Projects the panorama as if it were mapped to the inside of a cylinder. This projection mode works really well for wide panoramas, but it also keeps vertical lines straight.
Choose a layout projection, adjust the Boundary Warp slider, and select Auto Crop options in the Panorama Merge preview dialog. -
Once you've finished making your choices, click Merge to create the panorama photo. By default, a stack containing your source files and the merged photo is created, with the merged panorama visible on the top of the stack. A suffix Pano.dng is appended to the filename of the merged photo.
The resulting merged Panorama photo. The merged panorama photo is stacked with the source files.
You can apply all Edit panel settings to the merged panorama photo just as you would apply them to individual photos.

Command-click (macOS) or Control-click (Windows) to select a series of consistent multiple exposure bracketed source photos when in Photo Grid (
) view or Square Grid () view, or from the filmstrip appearing at the bottom when in Detail () view.Review the requirements for merging to HDR panorama.

In the HDR Panorama Merge Preview dialog, choose a layout projection:
- Spherical: Aligns and transforms the images as if they were mapped to the inside of a sphere. This projection mode is great for really wide or multirow HDR panorama.
- Perspective: Projects the HDR panorama as if it were mapped to a flat surface. Since this mode keeps straight lines straight, it is great for architectural photography. Really wide HDR panoramas may not work well with this mode due to excessive distortion near the edges of the resulting panorama.
- Cylindrical: Projects the HDR panorama as if it were mapped to the inside of a cylinder. This projection mode works really well for wide HDR panoramas, but it also keeps vertical lines straight.
-
You can use Boundary Warp slider setting to warp HDR panoramas to fill the canvas. Use this setting to preserve photo details near the boundary of the merged photo, that may otherwise be lost due to cropping. The slider controls how much Boundary Warp to apply.
Higher slider value causes the boundary of the HDR panorama to fit more closely to the surrounding rectangular frame.
-
Once you've finished making your choices, click Merge to create the HDR panorama photo in a single step. By default, a stack containing your source files and the merged photo is created, with the merged HDR panorama visible on the top of the stack. A suffix HDRPano.dng is appended to the filename of the merged photo.
You can apply all Edit panel settings to the merged panorama photo just as you would apply them to individual photos.
To successfully merge your selection of photos to an HDR panorama, ensure that all the requirements listed below are met. If any of these requirements are not met, Lightroom displays the Unable to create HDR Panorama dialog box with a message 'Unable to create an HDR Panorama with your selection. Attempt to create a normal panorama instead?' when you try to merge the photos.
- All the images in your selection must contain the exposure metadata - Exposure time, f-number, and ISO.
- Each set of bracketed exposures in your selection must have the same number of images. For example, if you chose to bracket with three images, then all the sets in the selection must also use three images.
- Each set of bracketed exposures in your selection must have the same exposure offsets. For example, if your first set has exposure offsets of (0, -1, +1), then all other sets in the selection must follow the exposure offset pattern. The image sets can have different exposure values; only the exposure offsets pattern must be consistent across all the sets.
- Each set of bracketed exposures must be captured
contiguously . For example, if you've considered a bracket size of three while capturing the images then the first three images in the sequence become part of a bracket set, the next three images in the sequence become part of another bracket set, and so on. - Within a set of bracketed exposures, the images must not have the same exposure value.
