Exif-stat

Extracts some metadata from image files and stores it in CSV file for additional analysis.

What it does?

It scans all JPEG files in a given folder (including all subfolders recursively) and tries to read EXIF data. Some of that data is then written to a file.

It is expected that scanned JPEG files are pictures from digital cameras.

Following information is extracted:

• Camera Make
• Camera Model
• Photo Creation time
• Iso number
• Aperture F-number,
• Exposure time
• Focal length
• Equivalent focal length for 35mm
• Exposure compensation
• Flash
• ExposureProgram (PASM, etc.)

Supported EXIF data

Only standard EXIF tags are parsed. Of the vendor-specific tags only some Nikon tags are parsed to retrieve ISO value when it is not present in Exif IFD.
