How to use perspective correction to straighten tilted room photos

Straighten leaning walls and tilted verticals in seconds with the Perspective tool — pixel-perfect geometry, no AI, no credits. Here's exactly how it works.

Walls that lean inward or outward throw off the whole staging result — furniture looks like it's sliding downhill, the floor reads tilted, and buyers instinctively distrust the photo without knowing why. The Perspective tool fixes that in seconds: you mark two lines that should be vertical, preview the correction, and apply it. It's straightforward geometry — no AI, no waiting, no credits.

What perspective correction does

Perspective straightens keystoning — the converging verticals you get when the camera is tilted up or down. It's a deterministic image warp computed right in your browser (the same math architects' "tilt-shift" lenses do optically), so it's instant and exact. Nothing about the room is reimagined or generated; the pixels are simply re-projected so vertical lines stand up straight. In the mode picker it's described as "Make verticals vertical — pixel-perfect, no AI."

Perspective is included on every plan.

When to use it

Reach for Perspective when:

  • Walls lean inward at the top (the most common case — camera tilted up)
  • Walls splay outward at the bottom (camera tilted down)
  • Door frames, window frames, or wall corners look noticeably slanted
  • The floor or horizon reads as tilted

Don't bother correcting walls that are already close to vertical — the staging model tolerates small imperfections, and over-correcting introduces its own distortion. (Better still, get verticals right in-camera — see How to photograph empty rooms.)

How to use it

  1. Switch to Perspective mode

    In the staging command bar, open the mode picker and choose Perspective (the frame icon). It sits alongside Stage, Declutter, Twilight, and Sky.

  2. Mark two verticals

    On first use you'll see a short prompt titled "Mark two verticals." Drag the fuchsia and cyan lines so each one runs along something that should be straight up-and-down — a wall corner, a door frame, or a window edge. Each line has a handle at the top and one at the bottom. Dismiss the prompt with Got it and drag away.

  3. Preview the correction

    Click Preview correction (the eye icon) to see the straightened result live. A dimmed border appears around the image showing the pixels that will be cropped away — straightening pushes the corners outward, so the final image is the largest upright rectangle that fits inside the warp. Use Reset to snap the lines back to vertical and start over.

  4. Apply

    With the preview showing, the button becomes Apply correction (the check icon). Click it and the straightened image saves to the room's timeline, labelled "Perspective corrected."

    Before and after: the leaning original and the straightened result in the timeline

A couple of details worth knowing: the Apply button stays disabled until you actually move a line (untouched lines mean there's nothing to correct), and the first click turns the preview on while the second applies it — so you always see the result before committing.

Two ways in: a free revision or a fresh photo

There are two ways to reach the Perspective tool, and they differ only in cost:

  • On a photo you've already staged — applying Perspective is a free revision. It's threaded into that photo's timeline like any other revision.
  • Starting from a brand-new upload — saving that photo into the project uses one credit (the same as the first staging of any new image). Re-using a photo that's already in the project is free.
