Everything you need to know about Perspective
Perspective corrects or adds geometric distortion caused by camera angle. Fix converging vertical lines in architecture shots, correct keystone distortion from projectors, or create intentional perspective effects for dramatic compositions.
Parameters
- Horizontal (Keystone)
Corrects horizontal perspective distortion. Negative values (-40% to 0) compress the top edge and expand the bottom – use this to fix photos taken looking down. Positive values (0 to +40%) compress the bottom and expand the top – use this to fix photos taken looking up at buildings or screens. - Vertical (Tilt)
Corrects vertical perspective distortion. Negative values compress the left side, expanding the right – for images shot from the right. Positive values compress the right side, expanding the left – for images shot from the left.
Presets
- ⬒ Floor View
Corrects images shot looking downward (top wider than bottom) - ⬓ Ceiling View
Corrects images shot looking upward (bottom wider than top) - ◧ Left Tilt
Corrects images shot from the right side - ◨ Right Tilt
Corrects images shot from the left side - ▢ Reset
Returns both sliders to zero (no perspective change)
How It Works
The filter remaps the image coordinates to simulate viewing the image from a different angle. This transforms the rectangular image into a trapezoid shape, which corrects (or adds) the appearance of converging lines caused by perspective.
Tips
- Use Horizontal correction to straighten buildings photographed from ground level
- Use Vertical correction to fix photos of screens, signs, or documents taken at an angle
- Transparent areas may appear at edges after correction – crop to remove them
- Combine with Rotate for complete geometric correction
