In his book Understanding Exposure, ace photographer Bryan Peterson postulates that there are three picture-taking situations for which your attention to aperture choice is paramount. These three picture-taking situations or compositions are:
1. Storytelling compositions (fully stopped)
2. Isolation compositions (wide open)
3. Who cares compositions (f/8)
Showcased below are my attempts in capturing the aforementioned compositions. See how the background goes from clearly defined to a smooth blur with each subsequent opening of the aperture. Lens used in all the photographs is the Canon EF 50mm f/1.8 II and subject in the compositions, why, the humble Daylily in the parking lot of the local Costco.
