Exercise1 Focal length and angle of view
This exercise involved taking three photographs at different focal lengths.
 |
| P1 : 55mm @ f5.6 |
 |
| P2 : 18mm @ f4.5 |
 |
| P3 : 70mm @ f4.5 |
What was interesting here was how the comfortable viewing distance varied from about 66mm ( P1 ); 26mm ( P2 ) and 77mm+ ( P3 - arm not long enough!) ; and sacrifice of detail using the wide angled lens.
