A small tilted horizon can make a travel picture feel accidental. Straightening is a rotation followed by a crop; it does not reconstruct missing corners. The trick is to correct the tilt while keeping the important parts of the scene.

What to do

  1. 1.Identify a true horizontal or vertical reference.
  2. 2.Apply a small rotation.
  3. 3.Crop away the empty corners.
  4. 4.Compare before and after at fit-to-screen.

Find a reliable reference

Sea horizons, door frames and building edges help you judge whether the camera was level. In cities, perspective can make vertical lines converge even in a properly leveled photo. Decide whether you want a level horizon or a full perspective correction.

Rotate only as much as needed

Make a small angle change and compare the edges. Large rotations discard more of the frame and can cut feet, hair or a product label. An editor with perspective tools can address keystoning, while a simple rotation cannot.

Reframe after rotating

Once the horizon looks right, move the crop inward just enough to remove empty triangles. Check the upper corners and the main subject one last time; a corrected line is not worth losing half the scene.

Watch out for this

A wide-angle lens can bend straight lines. Rotation cannot undo all lens distortion or perspective.

Frequently asked question

Should every horizon be perfectly straight?

Usually for seas and architecture, but deliberate camera angles can work well. Correct accidental tilt, not intentional composition.
