Exercise 3 solution

This depends on your own pictures. A sample entry:
"Window portrait (best): soft window light (Chapter 4); exposure right after +0.7 EV compensation (Chapter 6); focus on the nearer eye at f/4 (Chapter 3); subject on a left power point (Chapter 5); colour slightly orange, so set white balance to a cooler value next time (Chapter 7)."
Finish with three changes tied to chapters, for example: shoot raw for hard scenes (Chapter 8), use a tripod for landscapes (Chapter 9), and check the histogram after each frame (Chapter 8).
