Perspective correction for property photos, explained

Why vertical lines converge

When a camera points upward, parallel vertical lines appear to move toward each other. Wide phone lenses make the effect stronger near the edges of the frame.

The correction is geometric: the image is transformed until important architectural lines become vertical again, then the empty edges are cropped.

Correct without exaggerating

Straight walls do not require stretching the room sideways. A careful correction preserves proportions and accepts a modest crop rather than using aggressive warping to keep every pixel.

• Level the horizon first
• Use door frames and corners as references
• Protect furniture proportions
• Review the crop around fixtures

Capture makes correction easier

Hold the camera level, step backward instead of tilting upward, and use the standard lens where space allows. Leave a little extra room around the edges for the later crop.

Review the result

Check cabinets, mirrors, door frames, and objects near the image edges. If those elements look stretched, the correction has gone too far.
