The challenge for the week of Feb 26 to March 4, 2018 at 52Frames.com is the theme of “Depth of Field”. This is about exploring the ways in which the aperture setting on a camera cause a shallow area of focus in an image. Here’s an example done by Lisa Shea, of a flower blossom.
See how the petunia itself is in focus, while the world behind it is out of focus? This is created with a shallow depth of field. The aperture of the lens was wide open, causing that to happen.
