Full screen vs. pixel peep
Apr 13, 2012

After years of looking for the best resolution, lenses, sensors, tripods...I did a quick sanity check with a simple calculation:

  • the monitor screens we almost all watch our pictures on have at most 1200 lines which, with the usual aspect ratios (3/2 and 4/3), give us about 2M pixels for full screen pictures. Most of the time there is something else on the screen so we use much less than 2M pixels.

  • so we admire our own and other people's great pictures downscaled to less than 2M pixels,

  • unless we pixel peep, i.e look at less than the full picture.

Don't take me wrong, I am proud of a landscape I shot with no shaking which I can peep down to the pixel, and I do panoramas with multiple of these shots.

But, while it is useful to have a more pixels for cropping, enlarging for posters and above, and to be comfortably below the Nyquist sampling limit of the pixels, let us remember that 99.xxx% of the time we look, judge and admire pictures downres'd at less than 2M pixel.
