Depth of Field Explained

Knowing how to control the depth of field is one of the basics of photography, but do you know why a large aperture results in a shallow depth of field?
Artist Justin Snodgrass has created this 20 minute tutorial that explains it all in detail. The video have some references to a “35 mm adapter” as it was made for videographers working with these kind of adapters, but the information applies to all sorts of photography.
