• HDR preview now supports photos from older iPhones. • Auto no longer clips HDR highlights. • Bug fixes.

Real HDR, everywhere you edit • Real HDR preview on HDR-capable screens. • AI-filled corners get proper HDR: lights and highlights carry on seamlessly into the filled areas, in whatever order you edit. • Grading before you correct perspective or fill now keeps its HDR in the saved photo. • Photos open faster, and pinch and zoom work reliably after sharing a photo into the app. • Auto perspective handles more scenes. • On iPad and Mac, buttons keep a comfortable size instead of stretching across the screen. • Stability and memory improvements.

Sign-in keeps your free credits, truer HDR results • Signing in with Apple, Google or email now keeps the free AI credits you started with — they move to your account instead of being left behind. • The result screen now shows HDR photos the way the Photos app does: bright highlights and true, rich colour. • Highlights and Shadows rebuilt: recover skies and lift shadows without halos or banding. • Saves keep their real HDR after perspective correction, AI fill and grading. • The app opens even without a connection, and very large photos are handled safely. • Bug fixes and refinements.

New Warp tool, better tone tools, smoother gestures, Mac support • Brightness and Contrast rebuilt: highlights compress instead of blowing out, shadows lift without crushing, and dark areas no longer pick up colour noise. • New Brilliance tool: brightens dark parts of the photo and eases back the bright ones — for backlit buildings and flat, overcast light. • Saturation: isolate or exclude several colours in turn — each round adds to the last. White balance switches off with a second tap, and the sample point can be steered from anywhere on the photo. • Warp: a new Keystone tool that bends the inside of the photo while the edges stay put — for the small lens distortions left after perspective correction. Drag to push, turn the wheel to set the reach. • Bowed and warped HDR photos now save with their real HDR intact. • Auto crop understands bowed edges and keeps them out of the frame. • Crop gestures start from rest and move smoothly, with one consistent feel in Auto crop and Free crop. Zooming out lands edge to edge where your frame was. • On a Mac: pick photos from any folder, resize the window, and zoom and pan with the trackpad or mouse wheel. • Bug fixes and refinements.

Faster batch corner fill • Batch fills now prepare photos in parallel and send up to five at a time — a batch of five finishes in about one round-trip. • Fills are sent at the AI model's exact working size: half the upload, no seam artifacts. • Filled photos keep their frame: pan or pinch to look closer and the photo springs back. Tap Redo to recompose and fill again. • Add photos to a batch with the + tile at the end of the filmstrip; they're corrected right away. • The Auto crop button sets the mode for every photo; a pinch-out or pan-and-hold exit changes only the photo under your fingers, and hands over without a jump. • Smoother switching between photos in the carousel. • Single photo: Auto crop is available on any photo, with the same pinch-out exit as batch. • Bug fixes and performance improvements.

Batch editing, streamlined • Crop right in the review screen: drag and pinch the big preview to reframe each photo, and tap the filmstrip to move between photos. No more trip to a separate screen. • Switch any photo between Auto crop and Free crop from the top bar. Push the frame past the photo's edge and it's marked for AI fill automatically. • Long-press a photo in the batch grid to remove it. Fixes • Auto Crop: zooming out past the limit no longer leaves empty areas in the frame. • Smoother batch progress and Save button.

New in Adjust • White Balance: one tap to neutralize a color cast, with a dial to ease it back. Long-press for an eyedropper and pick the exact spot that should be neutral. • Color-targeted Saturation: long-press Saturation to isolate one color, or to change everything except it. • Zoom in to inspect and the view stays put while you switch tools. Also new • 10 free AI edits for new users, up from 5. • A warning before leaving the editor would discard your changes. • Refined look for menus, sheets and messages throughout the app. • The contact form stays clear of the keyboard. • Fixes for users who were missing their free AI edits.

• Fine-tune the crop on the final screen: pinch and pan, and that framing is what gets saved • Batch editing: mark photos for AI corner fill and fill them all in one step • Auto colour now carries Apple's own Auto Enhance for a natural, punchy look • Upgrading your plan, or switching to yearly, now takes effect immediately with a full credit refill • Fixes for crops not carrying into Keystone and Adjust, and for the save button's "as new" switch

Keystone Photo Studio is now Keystone Photo Lab. • Batch editing: fix perspective, crop and colour across up to 30 photos at once, review each one, and save them all in a single step • AI corner fill for a whole batch in one tap • Auto colour now carries Apple's own Auto Enhance for natural, punchy results • Saves keep HDR, location and lens information • Full-bleed view while adjusting the crop frame

• More reliable subscription upgrades — changing plans no longer shows a false "purchase failed" message. • Smoother transitions when switching between the Keystone, Adjust, and Recreate tabs. • Clearer message when a purchase can't reach the network. • Refined the account panel — swipe down to dismiss.

iPad support. Keystone Studio now runs on iPad in all four orientations, with the image preview scaled to the larger screen instead of the phone layout. Fixes a bug where a photo taller than the preview area could overflow and cover the Save button on the results screen. Adds a back arrow to the Recreate and Upscale result screens, so you can return to your original input instead of only editing the result again.
