Camera Bracket settings
Learn how to create HDRs, Panorama, and HDR Panoramas using the Photo Merge feature.
Lightroom desktop lets you easily merge multiple exposure-bracketed photos into a single HDR photo and standard exposure photos into a panorama. Moreover, you can also merge multiple exposure-bracketed photos (with consistent exposure offsets) to create an HDR panorama in one step.
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.

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 |
Keep the following tips in mind when you take photos to be combined into an HDR photo:
For Automatic Exposure Bracketing, check your camera’s manual for instructions on how to use this mode on your specific camera model.
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.
Do any of the following to merge your selected photos into a single HDR photo:
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.
Low: Cures little or minor movement between frames
Medium: Cures considerable movement between frames
High: Cures high movement between frames
Select Show Deghost Overlay or press the O key on your keyboard, to see where deghost corrections appear in the merged HDR photo.
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.
You can apply all Edit panel settings to the merged HDR photo just as you would apply them to individual photos.
Keep the following tips in mind when you take photos to be combined into a panorama:
Command-click (macOS) or Control-click (Windows) to select a series of standard exposure source photos when in Photo Grid () view or Square Grid (
) view, or from the filmstrip appearing at the bottom when in Detail (
) view.
In the Panorama Merge dialog, choose a layout projection:
Spherical
Aligns and transforms the images as if they were for mapping the inside of a sphere, which simulates the experience of viewing a 360-degree panorama. If you have taken a set of images that cover 360 degrees, use this option. This projection mode is great for really wide or multirow panoramas.
Starting from Adobe Camera Raw version 11.4, you can experience more seamless results around the merged edges.
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.
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.
You can use Boundary Warp slider setting to warp 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 panorama to fit more closely to the surrounding rectangular frame.
Select Fill Edges to automatically fill the uneven edges of the merged image.
Select Auto Crop to remove undesired areas of transparency around the resulting merged photo.
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.
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.
Do any of the following to merge your selected photos into a single HDR photo:

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.
