QSDC

Plug in your SD card and browse without importing to Photos. Cull fast, check focus at 100%, RAW (RAF) support, and save only the photos you pick!

QSDC is a fast culling and viewer app for the photos on your SD card — without importing them first. Plug in a card reader, review on the spot, and download only the shots you want to Photos. It never writes to the card — fully non-destructive.

WHO IT'S FOR · Photographers who need to cull hundreds of shots quickly after a shoot · Anyone who wants to check and select high-resolution RAW (RAF, etc.) in the field · People who'd rather keep their camera roll clean and import only the keepers

KEY FEATURES · Import-free SD browsing — open the card and view without importing · Fast culling marks — sort into Keeper / B-cut (maybe) / Reject, and filter by mark · Photos-like browsing — smooth zoom transition, swipe paging, swipe down to dismiss · 100% zoom — check focus and detail at native pixels · Composition guides — rule of thirds, golden ratio, golden triangle (long-press to switch) · RAW dual-path — fast embedded previews for browsing, full decode for precise checks · Sort — by capture date, newest or oldest first · Download keepers only — save just the photos you picked; already-downloaded shots are marked, and duplicates can be skipped · Metadata — camera, lens, shutter, aperture, ISO, focal length (EXIF) · Per-card thumbnail cache — set retention and a size cap, with low-space warnings · Camera-roll grid — adjustable columns, portrait and landscape · Non-destructive (read-only) — never deletes or alters photos on the card
