Video: You don't need to know enough about it to build one yourself, but a little knowledge of how digital cameras actually work can help improve your photography game. So if you've got an extra 13 minutes at your disposal today, watch this wonderful explainer of how a camera's sensor works.
The video, hosted by John Hess of Filmmaker IQ, starts off with a crash course on how traditional photographic film used to work. But it also covers how an electronic sensor is able to convert captured light into a digital image, the differences between CCD and CMOS sensors, and the pros and cons -- both technically and artistically -- to each engineering approach.
There won't be a test afterwards, but you'll definitely be more camera savvy.
