21.6.12

Focal length and angle of view


My task for the first exercise was to take a photo with both eyes open so that the image seen through the lens was the same size as through the other eye. As I needed to be in a set position for this shot and the next, I photographed my bookshelf while sitting at the dinner table. I found that I had to have the zoom at its furthest telephoto setting of 55mm in order for the size to match in both eyes.
I then had to set the zoom to its widest view of 18mm and take the photo from the same spot. This made a big difference to the photo as almost the whole wall was in shot rather than the couple of shelves in the previous shot.
(Post to be updated when I have completed part two of this exercise)
