Welcome to Lensdays! This video is about seeing field curvature in any lens. The better you understand the photography equipment you own, the better you're going to be able to express your artistic vision and intent. Most photographers understand how depth of field works, but most don't understand what its actually doing in lens that they are using. Some lenses exhibit field curvature which can make you think things are in focus when they are not. Its also important to understand how depth of field works at scale. An f-stop of 2.8 is much wider the further from the camera you focus. So how can you visualize this? I have a trick for you.
