Keystone Photo Lab vs RawMask Studio

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.

Edit only the part of the photo you choose. RawMask Studio is a RAW photo editor built around masks: pick a detected subject or draw your own mask, then change the light, color, detail and focus of just that area while the rest of the image stays untouched. It opens RAW and ProRAW files as well as everyday JPEG and HEIC photos, and every edit happens right on your iPhone. MASKS FOR SELECTIVE EDITS - Automatic masks: on-device detection finds subjects such as people, cars and animals and turns them into ready-to-edit masks - Manual masks: radial, linear (gradient), brush and rectangle - Refine any mask with the Add and Subtract brushes - Soften the edge with Feather for smooth, natural transitions - Give every mask its own light, color, detail and focus adjustments RAW, PRORAW, JPEG AND HEIC - Pick photos straight from your Photos library with the system picker - Edit RAW and ProRAW captures with the same tools as regular photos A CLEAR, STEP-BY-STEP WORKFLOW - Frame: crop, straighten, rotate, aspect ratios and zoom - Light: exposure, contrast, highlights, shadows, whites and blacks - Color: temperature, tint, vibrance and saturation - Detail: texture, clarity, dehaze, sharpness and noise reduction - Focus: background blur with strength, range, feather and bokeh - Effects: vignette, grain and fade - Reorder or hide steps in Editor options to match the way you work COMPARE AND REUSE - Hold to Compare to check before and after at any moment - Save whole-photo adjustments as a Preset and apply it to another photo SAVE WITHOUT LOSING THE ORIGINAL - Save edit to Photos is non-destructive: the original stays intact and you can revert the edit in Photos anytime - Save a copy to Photos to keep the edited version as a new photo - Export as JPEG, HEIF or TIFF through the share sheet PRIVATE BY DESIGN - No account, no sign-in and no ads - Editing and subject detection run entirely on device, so your photos are never uploaded - Free, with no in-app purchases Open a photo, pick a mask and make one part of it shine.
