Photo Culling: RAW Sifter

RAW+JPG Cull — the fastest way to sift through a card full of photos on iPhone or iPad. Built for photographers who shoot RAW+JPG and need to get to the keepers before they leave the location. Plug in your SD reader, pick a folder, and the grid fills instantly. The App uses the embedded JPEG preview baked into every RAW file — no waiting for full decode, no import step, no cloud round-trip. Two thousand frames scroll as smoothly as twenty. WHAT IT DOES • Instant previews from RAW files using the embedded JPEG • RAW + JPG pairing: two files, one tile, one rating (or split them apart in Settings) • Star ratings 1–5, pick / reject flags, color labels • Swipe up to rate proportional to swipe length, swipe down to close • Double-tap or pinch for 100% zoom via Apple's Core Image RAW pipeline — a true full-sensor decode, not just an upscaled preview • XMP sidecars written next to every source file — your ratings show up in Lightroom, Capture One and Photo Mechanic without an import step • Safe reject workflow: move rejects to a _Rejects/ subfolder (reversible) or delete outright with confirmation • Filter by rating, flag, color, or file type • Works with SD cards, USB readers and any folder in the Files app • Session history: reopen the last card without picking the folder again SUPPORTED RAW FORMATS • Sony — ARW, SR2, SRF • Canon — CR2, CR3, CRW • Nikon — NEF, NRW • Fujifilm — RAF • Olympus / OM System — ORF • Panasonic / Lumix — RW2 • Pentax — PEF, DNG • Leica — DNG, RWL • Hasselblad — 3FR, FFF • Phase One — IIQ, CAP • Sigma (Foveon) — X3F • Samsung — SRW • Minolta / Konica Minolta — MRW • Epson — ERF • Mamiya / Leaf — MEF, MOS • Kodak — KDC, DCR • Adobe DNG — universal (iPhone ProRAW, DJI, Insta360 exports, Lightroom exports) • JPG, JPEG, HEIC, HEIF RAW decoding is powered by Apple's system RAW pipeline: if Photos or Preview on macOS can open the file, RAW+JPG Cull can too. WHY IT'S FAST Culling apps on the desktop are fast because they cheat — they read the embedded JPEG instead of decoding the sensor data. RAW+JPG Cull does the same thing, on iOS. Grid scroll, star-swipe, filter — all backed by the tiny JPEG hiding inside every RAW. Full-sensor decode only fires when you actually zoom in. PRIVACY No network access. No analytics. No third-party SDKs. Your photos never leave your device. XMP sidecars are written locally, next to the source file. See our privacy policy in the App or on our website. WHO IT'S FOR • Event, wedding and sports photographers who want to cull on the plane home • Travel photographers backing up to iPad in the field • Anyone tired of waiting for Lightroom Mobile to import 800 RAWs before they can look at a single frame Requires iOS 17 or later. Universal — same purchase runs on iPhone and iPad.
