Shot a landscape in several overlapping frames? The free Hugin stitcher joins them into one panorama, using shared image details to align the frames. Its workflow lets you adjust control points, crop boundaries, and perspective and exposure settings before creating the finished image.
Add overlapping photos and align them
Start by loading photos that show some of the same scene. Hugin uses those shared areas to determine how the frames fit together. Control points mark corresponding details in different images, such as a corner or other distinct feature. Automatic alignment can establish matches, and you can add or adjust points when the placement needs refinement.
The Images and Control Points parts of the workflow let you work with the source frames and their matches. Accurate points give the alignment process clearer references, especially where the scene has noticeable changes in perspective.
Correct the panorama before stitching
Hugin provides controls for cropping images and adjusting perspective and exposure. Cropping sets the edges of the panorama, while perspective and exposure adjustments address differences among the contributing frames.
- Inspect the matched points and refine alignment where needed.
- Set the crop to remove unwanted edges from the composition.
- Adjust perspective and exposure before producing the panorama.
Choose a projection and create the image
The Stitcher stage produces the joined panorama after alignment and adjustments. Hugin supports panorama projections such as rectilinear, cylindrical, and equirectangular, which shape how the scene is represented in the final image. The projection choice affects the panorama's geometry, so select one suited to the view you are assembling.

What does Hugin do?
It joins multiple photos into a panorama, aligning their overlapping areas and blending them into a wide image.
What are control points in Hugin?
They identify the same detail in separate photos so Hugin can align the images.
Do the photos need to overlap?
Yes. Shared areas give Hugin details it can match between frames.
