Explore depth of field and how aperture, distance, and focal length shape focus in photography. Learn about focal plane and practice through a series of tests across seven videos.
Explore depth of field, the plane of focus, and how aperture shapes what remains sharp. Learn to isolate a subject or keep the scene evenly in focus.
Explore how aperture and distance shape depth of field, showing that lower f-stop values yield shallower depth of field and moving farther from the subject deepens it.
Explore how focal length influences depth of field and perspective compression, through side-by-side lens tests and experiments.
Explore how aperture and focal length shape depth of field across 16, 35, 105, and 200 mm lenses, with f-stops from 2.8 to 16.
Explore how camera distance to the subject changes depth of field at the same f-stop, with background blur varying when focusing on different targets at 200 mm and 16 mm.
Explore how focal length shapes depth of field, showing how backgrounds blur increasingly from 24mm to 95mm while keeping the subject in focus at a given distance.
discover how focal point controls depth of field by focusing at different image points and distances; learn how f-stops and focal length affect what stays sharp.
What is Depth Of Field (DOF)
The distance between the nearest and the furthest objects that give an image judged to be in focus in a camera.
One fo the key elements of aperture is depth of field. All variables in photography have a give and take, and with your aperture as we gain light we also lose depth of field. But aperture is not the only variable the affects depth of field, so we will take a look at those other variables.
In this lesson you will see how DOF is controlled by two key elements F-stops and distance from camera to subject and we'll take look at a few other variables.
