Photo Stats for 2006

by Dirk Paessler

With Exposureplot (Freeware) you get statistics about your photo collection. Exposureplot reads the focal length, aperture, ISO and shutter speed from your photos and shows a statistics for each masurement.

What I learnt about my photos (stats for the 9.700 “selected” photos from 2006)

  • ISO Settings
    • 40% were taken at ISO 50/100
    • 18% at ISO 200
    • 15% at ISO 400
    • 10% at ISO 800
    • 8% at ISO 1600
  • Apertures
    • 25% had an aperture of f/2.8 (due to my favorite lens (Nikkor AF-S 17-55 f/2.8) and that’s also the largest aperture of the Canon S70)
  • Focal Lengths (calculated for 35mm equivalents)
    • 42% had a focal range between 18mm and 28mm
    • 25% between 32mm and 64mm
    • 25% had 80mm (the long end of the 17-55)
    • 9% with 128mm (the 85mm/f1.8)
    • 3% with 184mm
  • Shutter Speeds
    • Most used speed is 1/30s (10%), followed by 1/60s and 1/40s
    • 22% of the exposure times are between 1/10s and 1/30s
    • Some 55% of all photos have exposure times between 1/10s and 1/100s (combined with f/2.8 and higher ISO settings these look like the usual values for a photographer that favours available light over dead-flashed situations 🙂 )
