To stitch a multi-row panorama in Photoshop, shoot overlapping rows with locked exposure, load the files through Photomerge, choose a layout and then correct perspective and edges with Adaptive Wide Angle, Transform tools and Content-Aware Fill. Good shooting habits remove most problems before you open the software.
Shoot Rows That Stitch Cleanly
- Use manual exposure, manual focus and a fixed white balance for the entire set.
- Level the camera, ideally on a tripod, and shoot the first row from left to right.
- Tilt up or down slightly and shoot the next row, keeping roughly 30 percent overlap in both directions.
- Avoid moving subjects in the overlap areas where you can.
The overlap figure is a general guide. Wider lenses and nearby subjects may need more.
Merge in Photoshop
- Process the raw files with identical adjustments, or merge directly from Lightroom if you prefer.
- In Photoshop, choose File, then Automate, then Photomerge, and add your files.
- Try the Auto layout first. If the shape looks distorted, test Perspective, Cylindrical or Spherical for wide views.
- Turn on Blend Images Together and Vignette Removal when your lens shows falloff.
- Leave Geometric Distortion Correction on if you shot with a wide lens, and compare the result with it off.
- Click OK and wait for the layered file to build.
Understand Perspective Errors
Multi-row panoramas often show bowed horizons, leaning buildings or stretched corners. These come from projecting a wide field of view onto a flat plane. Different layouts trade off which error you see.
| Layout | Best for | Typical drawback |
|---|---|---|
| Perspective | Narrow fields of view | Edges stretch on wide scenes |
| Cylindrical | Wide landscapes | Straight lines can curve |
| Spherical | Very wide or multi-row sets | Needs more cropping |
Correct the Result
- Bowed horizon: Use Filter, then Adaptive Wide Angle, and draw constraint lines along the horizon and tall edges.
- Leaning verticals: Use Edit, then Transform, then Perspective or Skew, or the Upright tools in Camera Raw.
- Empty edges: Crop in, or select the gaps and use Content-Aware Fill.
- Visible seams: Zoom in, check the layer masks and brush in a softer transition by hand.
Work Efficiently
Save the merged file as a layered master before you apply final sharpening or color changes. Work on a copy for web export, and keep notes about the layout and settings that worked for each scene so that you can repeat them on later shoots.
FAQ
Why does my panorama fail to merge?
Usually there is too little overlap or not enough detail in the overlap, such as plain sky. Add frames with more overlap or include recognizable detail.
Should I flatten the layers?
Keep the layers until you finish corrections, then save a master file and a flattened copy for export.
The Short Version
Shoot level, overlapping rows with locked settings, merge with the layout that suits your field of view and fix leftover distortion with Adaptive Wide Angle and Transform tools. Fill edges last and keep a layered master.
