Half vs LogLab

Half-frame cameras fit two photographs where a normal 35mm frame goes. So when the lab scans your film, you get back one wide image holding two separate pictures, divided by the dark strip of unexposed film between them. Half-Frame Joiner finds that divider, splits the scan into its two real photographs, and lets you rejoin any two of them into a new pair — ready to print. SPLIT YOUR SCANS Pick your half-frame scans straight from your photo library. Each one splits automatically, cropped from the original at full resolution and never resampled. Scans the detector isn't sure about are left whole, so a real picture is never cut in half by accident — and you can always split those by hand. REJOIN ANY TWO Tap two frames and see them joined instantly. Pair them back the way they were shot, or combine frames from completely different rolls to make something new. Every combination is a tap away. MADE FOR PRINTING Choose 4×6, 5×7, or the original aspect ratio before you save, and the app composes to exactly that shape so a lab won't crop your photographs unexpectedly. Pinch to zoom, drag to reposition, and rotate each photo inside its half of the frame until it sits right. The black divider between the two pictures is recreated the way film actually looks, not pasted in as a hard line. EXPORT WHAT YOU NEED Save joined pairs, or export single frames on their own — as TIFF for maximum quality or JPEG for smaller files. Everything goes back to your photo library. KEEP TRACK Tap the info button on any photo to see every join it appears in, and browse everything you've made in the Created tab. PRIVATE BY DESIGN Half-Frame Joiner works entirely on your device. No accounts, no analytics, and no network requests at all — it runs in Airplane Mode. Your photographs never leave your iPhone.

LogLab is a focused, professional color grading tool for iPhone and iPad. Film in Log right in the app, or import footage shot in Apple Log, Apple Log 2, Sony S-Log3, Canon C-Log2/C-Log3 or DJI D-Log, and grade it with accurate, colorimetrically grounded log-to-Rec.709 conversion in a real-time, 10-bit Metal-powered preview. LOG CAMERA Capture Log video with any iPhone. Pro iPhones record Apple Log and Apple Log 2 natively; every other iPhone records LogLab Log, an Apple Log–compatible format converted from the camera's 10-bit HDR video. Choose 4K or 1080p, 24 to 120 fps, your aspect ratio, and high-bitrate HEVC or ProRes 422 HQ on iPhones that support it. MANUAL GRADING Fine-tune exposure, white balance (temperature & tint), highlights, shadows, saturation, contrast, grain and halation with precise, responsive sliders — and undo any change. LUTS Browse a set of built-in creative looks, or import your own: .cube and .3dl LUTs, whole LUT folders, or DaVinci Resolve PowerGrades (.drx). LogLab converts your clip to whatever log format a LUT was made for, and LUT thumbnails preview each look on your own footage. ASPECT RATIO Crop to 16:9, 4:3, 1:1, 3:4, 4:5 or 9:16 — centered and distortion-free, ready for any platform. COMPARE & REVIEW Drag the before/after handle over your preview to compare your grade with the untouched source. EXPORT Export to MP4 or MOV in H.264, H.265 or ProRes 422 HQ, straight to Photos or Files, with your original audio. Copy a grade from one clip and paste it onto another to keep a consistent look across a whole shoot. Works on iPhone, iPad and iPhone Duo, with layouts made for every screen. LOGLAB PRO Unlock the Log camera, the full library of creative LUTs, LUT and PowerGrade import, and ProRes export.
