Straight verticals are non-negotiable in professional property photography. Walls that lean inward or outward immediately look amateur. Fortunately, modern software makes perspective correction straightforward.
Why verticals converge
When you tilt your camera upward (to include a ceiling or the top of a building), vertical lines converge — walls appear to lean inward. This is a natural optical effect, but it looks wrong in property photography where we expect walls to be perfectly vertical.
Prevention is better than cure
The best approach is to keep your camera perfectly level:
- Use your camera's electronic level
- Set up a grid overlay in your viewfinder
- Use a hot shoe bubble level as backup
- If you need to include more ceiling, step back rather than tilting up
Correcting in Lightroom
Lightroom's Transform panel offers several options:
- Auto: Lightroom analyses the image and corrects automatically. Works well for most interior shots.
- Guided: You draw lines along features that should be vertical or horizontal. The most precise method.
- Vertical: Corrects vertical convergence only. Good for exterior shots.
- Full: Corrects both vertical and horizontal perspective. Can be too aggressive.
- Manual sliders: Fine-tune with Vertical, Horizontal, Rotate, Scale, X Offset, and Y Offset.
My recommended approach
- Try "Auto" first — it works correctly about 70% of the time
- If Auto doesn't look right, use "Guided" and draw 2-4 lines along walls, door frames, or window edges
- Enable "Constrain Crop" to automatically crop out the white edges created by the correction
- Fine-tune with manual sliders if needed
Common mistakes
- Over-correction: Walls that lean slightly outward look just as wrong as walls that lean inward. Aim for perfectly vertical.
- Forgetting to constrain crop: The perspective correction creates white edges that need cropping.
- Correcting barrel distortion as perspective: Apply lens profile corrections first, then correct perspective.
- Ignoring horizontal lines: Floors and ceilings should be level too — not just walls.
Key Takeaways
- Keep your camera level during shooting to minimise correction needed
- Use Lightroom's Guided transform for the most precise corrections
- Always enable 'Constrain Crop' to remove white edges
- Apply lens corrections before perspective corrections
- Walls should be perfectly vertical — neither leaning in nor out
