Exercise: Focal lengths and different viewpoints
This exercise required the use of a telephoto lens and a wide angle one.
The previous exercise showed that using different lenses (different focal lengths), from the same place, means different views. But this one will show that using different lenses (different focal lengths that is) and changing the viewpoints as well, means a difference in perspective.
At first I didn't expect to see so obvious results. But after taking the pictures I understood what "difference in perspective" really means.
So the first photo is taken with a zoom lens, at 150mm focal lens. The "subject" is just a part of a pedestrian overpass, which has a lot of side bars that give some depth. When photographed with the lens at 150mm, the subject seems rather compact, the bars seem to be very close to one another, and the whole space seems compressed, and close to the viewer.
Photo 1 - 150mm focal length
(from further away)
When photographed with a wide angle lens (at 19mm focal lens), the same subject looks so different, I was amazed... I had to actually count the bars - there are five in the distance, and one barely visible, in the right lower corner of the picture, exactly as in the first photo. But there is so much depth in the second one, the bars in the distance seem to be very far away.
Photo 2 - 19mm focal length
(from closer to the subject)
I think this exercise was one of the most useful for me, so far. I didn't make this comparison before, so I had a really big surprise when I saw the difference, between the two photos. It gave me a deeper understanding of the focal length and the difference in perspective.
