SDCull vs Relay Camera Transfer

SDCull helps you sort photos directly on an SD card, external drive, or folder in the Files app. You do not need to import the photos first. Review photos one at a time or select several from the grid. Mark unwanted photos as culls and mark keepers as selects. Culls move to a _Culls folder. You can review them there before you delete them. Selects move to a subfolder on the card or to another drive or folder. SDCull copies each file and confirms the copy before it removes the original. SDCull supports common photo formats and RAW files, including ARW, CR2, NEF, DNG, and RAF. It can group matching RAW and Non-RAW files so that you can review and move them together. Other features include: • Sort by filename, EXIF capture time, or modification date. • Filter by file type or flag. • Zoom in to inspect detail. • View the camera, lens, exposure, and file information. • Undo flag changes. • Keep flags after you close the app. • Use keyboard shortcuts on an iPad. SDCull works offline and does not require an account.

Relay pulls your original photos straight off your Sony camera and onto your iPhone. No cable, no card reader, no cloud, no account. HOW IT WORKS Your camera sends images over your own Wi-Fi, or over your iPhone's hotspot. Relay catches them and puts them in your library. Out in the field with no network around, the hotspot works fine — and the address stays the same every time, so you set the camera up once. ORIGINALS, NOT COPIES RAW files arrive untouched, alongside or instead of the JPEG. You choose whether you want both, RAW only or JPEG only. WHILE IT ARRIVES You see the photo while it is still coming in, with the file name and how many megabytes have landed. AFTERWARDS Browse, zoom, mark favourites, select several shots at once by swiping across them, save to Photos or pass them on through the share sheet. Relay shows up in the Files app too, so other apps can reach your shots directly. SETTING UP Pick your model and Relay shows the exact menu steps for that body — they differ from camera to camera. If something goes wrong, you can see precisely what the camera and Relay are saying to each other. PRIVACY Everything stays on your iPhone and on your own network. Relay sends nothing out, collects nothing and has no account. Works with cameras that can send images over FTP.
