Here’s a new 18-minute educational video by Filmmaker IQ about the subjects of depth of field and its relationship to different lenses and sensor sizes. “Through some fundamental scientific demonstrations, we will clarify concepts like circle of confusion and lens equivalency,” the video says.
This latest video comes on the heels of equally informative lessons on the science of camera sensors, the history and science of lenses, and the features and properties of lenses. If you’re looking to wrap your mind around the math and science of fundamental photography concepts, these videos are a great place to start.
