Exercise 1.1 Histograms

This exercise required me to take 3 or 4 photographs one after the other with the camera in automatic mode, then compare the histograms. Working in auto mode felt really weird, I couldn’t even remember which symbol it was on the dial. I used a tripod to ensure consistent framing. When looking at the histograms I was struck by:

  1. the fact that you can see the changes in the histogram
  2. the degree of change from almost imperceptible changes in ambient sunlight
  3. the way the camera settings changed
  4. I was also intrigued by the way the colour of the white page changed from shot to shot.

All images at ISO100. The flash auto fired for all of them, which surprised me.  First image: 06/07/2016 15:33:15, 1/200sec at f14. Second image: 06/07/2016 15:33:44, 1/500sec at f8. Third image: 06/07/2016 15:36:24, 1/200sec at f13 . Two images removed from sequence because of the cat photobombing them or the focus being off (hence the gap). Histograms are screen-grabs from Lightroom, no lens corrections or auto-toning applied.
