We reviewed what we learned Week One then thought again about the relationship between aperture and depth of field. While we start to get the idea when we say "f/2 -- shallow depth of field and f/22 -- deep depth of field" actually trying this out in with some real world shots is always a good experiment. So, to make a photo where a person is in focus but the background is out of focus, we did the following:
1. Set your zoom lens toward telephoto -- 50mm or longer -- or use a telephoto lens. 90mm would be an excellent choice.We experimented, and soon everyone was able to produce a photo with the subject in focus and the background somewhat out of focus. This is a great way to emphasize the main subject of the photograph.
2. Set your aperature toward f/2 -- on most basic zoom lenses, you might only be able to go to f/3.5 or f/4 or f/5.6, but that's okay. If you can get closer to f/2, that will work even better.
3. Position yourself, your subject, and the background. Generally, you should be close to your subject and the background should be far away to achieve this result.
We then went on to begin the long and complicated process of thinking about compositional strategies. For example, we introduced the "rule of thirds" -- which I have posts on here and here and here.
We then looked at how to create a relationship in a photo -- between a subject and the negative space around them, between two or three people, and in various other senses.
Nearer the end of class, we looked at ways to think about the space we are photographing in and how this can change / work with our compositional idea.
