A couple of years ago I took a Photography 101 class at a local art school. It was a little more basic than I had hoped - I had already taught myself quite a bit from reading books and information online. However, there was one exercise the instructor had the class do which I think has helped me immensely in photography.
It's an exercise that teaches you about perspective - and how to use different focal lengths on your camera to make three or four very different looking images of the same object. The concept is old hat to seasoned photographers of course... but if you're fairly new to photography, give this a try:
- Head outside and find something you'd like to take a picture of. It can be anything, a person, a building, a tree, whatever...
- zoom your camera all the way out - typically this will be around 28mm to 35mm - and walk to a position where the top of your subject is at the top of your camera frame, and the bottom of your subject is at the bottom of your camera frame.
- Next, move back a ways and zoom in - again positioning the top of your subject at the top of the frame, and the bottom of your subject at the bottom of the frame.
- Finally, move even further back and take a third picture, zooming in even more and again positioning your subject as described.
When I did the exercise, I chose a gazebo at Leu Gardens in Winter Park, FL that had a second building behind it. It's not something that makes a very interesting photo, but worked well for the exercise. Here are the three photos I took:
In the 36mm photo you can pretty clearly tell that there are two separate structures. However, at 124mm the perspective has become very compressed and the two planters appear much closer to the gazebo. The doors to the other building also appear larger and closer. Then, at 264mm the perspective has become so compressed that the two buildings look as if they are one structure.
This compression of perspective is something I try to keep in mind when out taking photos now. When I first started, I'd zoom in on things too often, creating very flat/compressed looking images. Now I know better and usually try a few different perspectives by standing at various distances from my subject.
