Depth of Field and Apertures


I finished a very good lesson yesterday on apertures, it took pretty much the whole day, but I think I was able to successfully take a difficult concept and present it in a quick efficient way.

Aperture refers to the opening of the lens iris. It is important for many reasons, one of the most important is it's Depth of Field, or the plane which is in focus. Wide apertures have thin DOFs, smaller ones have larger DOFs. You can actually meausre them by taking pictures of rulers which I did for the video.

Do you notice how it get's blurry with wider apertures? This usually looks very nice for portraits.

The apertures used are f2.8, f5.0. and f22.
