Keystone Photo Studio
Tilt-shift lens & perspective
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Simple but powerful tool to fix perspective distortions, AI corner fill, generative expand, upscale and deliver results in full resolution, P3 color and native HDR.
PERSPECTIVE & KEYSTONE CORRECTION
Straighten converging verticals and fix keystone distortion in architecture, real-estate, and street photos. Tilt, rotate, and warp until every line is true.
AI CORNER FILL — AT FULL RESOLUTION
Correcting perspective leaves empty corners. Keystone fills them with generative AI at your photo's full resolution — no downscaling, no soft edges, no visible seams. Most apps fill at a fraction of the size; this one doesn't.
GENERATIVE EXPAND
Extend the frame beyond its edges — add sky, foreground, or breathing room with AI that matches your scene.
UPSCALE & RECREATE
Boost resolution and detail, or let AI recreate a cleaner version of your shot.
TRUE COLOR — DISPLAY P3 + HDR
Unlike editors that flatten everything to sRGB, Keystone preserves your photo's Display P3 wide-gamut color and HDR gain map end to end — so edits stay as vivid as the original on your iPhone's screen.
KEEPS YOUR ORIGINALS INTACT
Native HEIC/HEIF in and out, EXIF and location metadata preserved, saved in the same format to conserve space.
Simple, fast, private:
• No account required — start editing instantly
• Photos processed at full quality
• Latest cutting-edge AI models
Download Keystone Photo Studio and make every photo look like it was shot with a tilt-shift lens.
