The Photographer’s Guide to Depth of Field

Photography can be a simple form of art but at the core is a complex set of rules, mathematics and integral components that are used in the creating of any photos, on top of composition. This article is designed to be uncomplicated and explains what depth of field is and how you can use it to enhance your photography. At the core definition, depth of field is:

the portion of a scene that appears acceptably sharp in the image. Although  a lens can precisely focus at only one distance, the decrease in sharpness is gradual on each side of the focused distance, so that within the DOF, the unsharpness is imperceptible under normal viewing conditions.

That’s somewhat complicating to understand and just about every tutorial that I’ve ever read trying to explain depth of field refers to some math equations but essentially, depth of field is focusing on one specific element in your field of view and by adjusting the aperture setting on your lens determining what else will be in focus. If you want everything to be in focus you are aiming for deep focus, where as the foreground, background and everywhere else in the frame is all in focus and sharp.
