Depth of focus and polarization

Applications

In this week’s exercise, I experimented with depth of focus and polarization. For depth of field, we learned that the amount of focus in the depth of field is determined by the aperture setting. The smaller the aperture the longer the range of focus. So, I took two photos, the first is with the smallest aperture on my camera (I believe it was 4.6):

all-focused

In the second photo, the aperture is completely open (29):

very-focused

For polarization, we learned that the polarization filter filters some of the light that is captured is the lens, giving a much more detailed image. Here are the photos with and without the polarization lens:

Without polarization lens:

not-polarized

With polarization lens:
