What you will get

The photo rotated until the horizon or building lines are level, lens distortion corrected, as little cropped as possible, and any empty corners filled in naturally.

Common mistake

It straightens the wrong line, such as a sloping hill, and leaves the real horizon tilted.

Fix: Name the line in the bracket: “the sea horizon” or “the left edge of the building”. Natural slopes should stay as they are.

Also watch for

People near the edges look stretched after the lens correction. Add “keep people and faces undistorted, even if the edges are cropped”. Wide-angle correction can pull things at the borders.
The filled-in corners show repeated textures or odd shapes. Check the corners at full size. If they look wrong, crop slightly in an editor, or ask for “extend only the sky and the water”.

Try a variation: buildings

For architecture, write “vertical building lines” in the bracket and add “keep the walls parallel and straight”. This fixes leaning towers as well as tilted horizons.

Level only the sea horizon, leave the people and everything else untouched, and keep the filled corners natural.
