Photo file recovery works by reading the sectors of a storage device where deleted image data still exists before new files overwrite it. JPG, RAW (CR2, NEF, ARW), PNG, and video formats all remain recoverable in sectors after deletion until overwritten.
Part 1. How Photo Recovery Works
When you delete a photo, the device marks the storage sectors as available — the image data itself remains intact until something else is written there. Recovery software reads those sectors and reconstructs image files from their binary headers.
| File Format | Recovery Rate | Notes |
|---|---|---|
| JPG/JPEG | Very high | Simple structure, widely supported |
| CR2/CR3 (Canon RAW) | High with vendor tools | Fragmentation-sensitive |
| NEF (Nikon RAW) | High with vendor tools | Large files, check fragmentation |
| ARW (Sony RAW) | High with vendor tools | Vendor-specific header |
| PNG | High | Lossless, consistent structure |
| MP4/MOV video | Moderate-high | Large files more prone to fragmentation |
Part 2. Free Photo Recovery Tools
PhotoRec — Cross-platform, unlimited, open-source. Best for formatted cards and corrupted file systems. Recovers without original filenames.
Recuva — Windows only, unlimited free. Reads NTFS/FAT32 deletion records, preserves original filenames for recently deleted photos.
💡 Tip: When using PhotoRec on a camera SD card, select only "Image" and "Video" file types. Scanning for all types on a 128 GB card returns tens of thousands of unneeded system files.
Part 3. When to Use Paid Photo Recovery
Free tools use generic file signatures. Camera RAW formats (CR2, CR3, NEF, ARW) benefit from vendor-specific reconstruction:
- Fragmented RAW files — large files spanning non-contiguous sectors require manufacturer knowledge to reassemble
- Partially corrupted cards — vendor algorithms identify valid RAW structure even with partial corruption
- Preview accuracy — generic tools may show a preview for a RAW file that won't open in Lightroom
🗣️ r/photography user: "Generic recovery found 800 CR2 files — 200 wouldn't open in Capture One. Used a tool with Canon-specific algorithms and all 800 came back clean."
Part 4. Recover Photos With Ritridata
Ritridata recovers photos from SD cards, hard drives, and external drives with vendor-specific algorithms for Canon, Nikon, Sony, and DJI on both Windows and Mac.
🗣️ r/datarecovery tip: "For professional RAW recovery, camera-vendor-specific tools consistently outperform generic signature scanners on large RAW files. The difference is most visible with files over 30 MB."
Step 1 — Select the device (SD card, hard drive, or external drive)
Step 2 — Run a scan to find deleted photo files
Step 3 — Preview photos before recovering to a different drive
FAQ
What is photo file recovery? The process of finding and extracting deleted image files from storage sectors where they remain intact until overwritten. Works on SD cards, hard drives, USB drives, and external storage.
Can I recover RAW photos after formatting? Yes — after quick format, RAW files remain in sectors. Deep scan recovery with vendor-specific algorithms (Canon, Nikon, Sony) recovers CR2, NEF, ARW files with high integrity.
