## 📷📆 - photo-datestamper

Little script to add date caption to photos from their EXIF data.

## Notes on Exif data

There is [ExifRead](https://github.com/ianare/exif-py) or [Exif](https://exif.readthedocs.io/en/latest/index.html) which can also modify exif data (and is tested and documented).

Both seem to be alive but `ExifRead` should suffice.

```python
with open(file, 'rb') as f:
    # Don’t process makernote tags, don’t extract the thumbnail image (if any)
    tags = exif.process_file(f, details=False)
for tag in tags.keys():
    if tag not in ('JPEGThumbnail', 'TIFFThumbnail', 'Filename', 'EXIF MakerNote'):
```

Interesting keys (to be completed by further observations):
```
Image Orientation
Image DateTime
EXIF DateTimeOriginal
EXIF DateTimeDigitized
EXIF ExifImageWidth
EXIF ExifImageLength
```
