# Photo Corpus

A corpus of ~32k real-world photos with EXIF metadata, for developing and testing photo management software.

## Sources

| Folder | Count | Source | EXIF date coverage |
|--------|-------|--------|--------------------|
| `yfcc/` | 31,385 | YFCC100M (Flickr originals) | ~78% |
| `oi/` | 1,034 | Open Images (Flickr originals) | ~92% |

Photos are Flickr originals with intact EXIF (GPS, dates, camera info) where available. Photos without EXIF DateTimeOriginal have file mtime set to the Flickr upload date as fallback.

## Format

WebDataset-style tar shards (~1GB each):
- `yfcc/yfcc-0000.tar` … `yfcc-0024.tar`
- `oi/oi-0000.tar` … `oi-0002.tar`

Each tar contains JPEG files named by content hash.

## Usage

```python
import tarfile
from pathlib import Path

for shard in sorted(Path("yfcc").glob("*.tar")):
    with tarfile.open(shard) as tar:
        tar.extractall("photos/")
```
