Version 1.7.1 fixes a bug: • With "Left Cull / Right Select" on, tapping a zoomed-in photo could flag the wrong side. A tap on the left half of the screen now always culls, and a tap on the right half always selects, however far you zoom or move the photo.

Version 1.7.0 adds: • Zoomed RAW photos now stay as bright as the full-screen view. Before, some cameras' RAW files looked darker when you zoomed in. • A new Auto-exposure setting in Settings > RAW Zoom. Turn it off to see the plain RAW image, without the camera's brightness adjustments.

Version 1.6.2 adds: • Light, Dark, and Follow System appearance options. • Running cull and select counts in the photo viewer, including VoiceOver support. This version also fixes these problems: • Photos remain fitted to the screen when you rotate the device. Your own zoom and position remain unchanged. • The info panel reports the full size of a RAW image instead of the size of its embedded preview. • File moves now copy and confirm the file before they remove the original. • Removing a card while SDCull is open no longer clears saved flags. • A zoomed photo releases its memory when you leave the viewer. • The message for moving one file from a RAW and Non-RAW pair is clearer.

This update brings several bug fixes and improvements following our recent 1.6 release: • Added support for Camera HEIF (.HIF) and .jfif files. • Fixed an issue where oddly-structured RAW DNG files showed color noise in their thumbnails or appeared as blank previews. • Fixed a bug where all-RAW folders could be mislabeled as "Only Non-RAW Files" in the workflow banner. • Improved accessibility by fixing text clipping and overlap issues with large Dynamic Type sizes in the folder picker and onboarding screens. • Added a visual indicator for unsupported or corrupted thumbnails in the gallery grid. • Refined terminology across the app to accurately refer to "non-RAW" files (which includes HEIF, PNG, TIFF), instead of just "JPEGs". • Fixed an issue where high-resolution zoom detail wouldn't load for certain preview-capped RAW files.

New in this version: • Undo — revert any flag with the new undo button (or Cmd+Z on a keyboard), step by step, all the way back. • Your session survives — cull and select flags are now remembered if you close the app mid-cull and restored when the folder reopens. • Sort your shoot — order by filename or date, ascending or descending, with natural numeric ordering (DSC_2 before DSC_10). Choose in Settings whether dates use EXIF capture time or the file's last-modified time. • Flag filter — tap the new Culls / Selects / Unflagged counters above the grid to review exactly that set before you move anything. • Photo info — one tap in the viewer shows capture time, camera, lens, shutter, aperture, ISO, focal length and file size. • Sharper zoom — zooming in loads extra detail for critical focus checks, and you can now pan with one finger while zoomed. • Safer moves — photos with the same name in different folders can no longer collide: moves preserve your subfolder structure in _Culls and your selects destination, and RAW+JPEG pairing is now per-folder. • Polish everywhere — position counter and end-of-folder summary in the viewer, haptic feedback when flagging, the grid follows you back from the viewer, better VoiceOver support, and many performance and stability fixes.
