This exercise was designed to help us find the "standard" focal length for my camera. As my Nikon D300 has a multiplier of 1.5 times focal length my initial thought was that the standard for this camera would be:
1.5 x 50 = 75mm
However in doing the exercise I found that for the standard length was around 55mm. This was very surprising as it seems I was completely off the mark with my earlier assumption. I actually went back and did the exercise for a second time on a different subject to check my results.
I ended up taking three photographs, at 18mm, 55mm and 200mm. After printing on A4 paper, I then measured the distance that each image had to be held in order to appear the same size as my view.
The results were as follows:
18mm -> ca. 6cm - too close to really focus on the paper!
55mm -> ca. 70cm - This was basically just less than arms length.
200mm -> ca. 160cm - only possible with the help of my wife as my arms don't reach that far!
