If you are a photographer or a video person in serious training you are going to need to understand the term depth of field. Depth of field is kind of like a grammar concept.
When you want to take better photos or shoot video you need to shift your visual perception about what is in the foreground, what is in the background and how light will affect the quality of the image or recording. Add the lens, focal length and a bunch of other factors to juggle; it can be overwhelming
Dyland Bennet has a tutorial video on explaining depth of field. This is one man's attempt at an explanation.
If you like this one also check out his video explaining F-Stops and Understanding ISO.
If you a casual point and shooter you do not have to watch this video. Nope. I don't want to call it vidgeeky but it is 16+ minutes for a reason.
