Lab 2: Aperture

Lab 2 : Aperture

1. Shoot a still life scene:

By having a larger aperture, the picture's background will be more blurry and by having a smaller aperture, it will be more sharp. With a larger aperture, we can tell what the background is but we can't see the details precisely. However, with a smaller aperture, every element in the picture is sharp. With an aperture between those two (larger & smaller), the background will be blurry but we can see more details in it. For this kind of picture (still life), I think the Shallow DOF is more effective because it gives more emphasis on the subject than the Deep DOF picture.

2. Shoot a portrait:

With a larger aperture (1st), it makes the eyes focus more on the subject than the background because we can't see the details clearly. With a smaller aperture (2nd), we can see more details in the background so our eyes are moving a multiple places in the picture at first look. I think it is good to have a blurry background for portrait but not too blurry and we want to focus on the subject more than sharp background. Maybe a medium DOF is good for portrait.
