Lens Diffraction Explained


Several years ago, I had a student drop me as his teacher because I kept telling him to stop shooting his landscape images at f/22.

I did my best to explain diffraction to him, but my efforts were not good enough, or he didn’t want to believe me. Either way, I wish this video by Steve Perry of Backcountry Gallery was available for me to show him. Steve does a great job explaining what lens diffraction is, how it can spoil your image, and how to avoid it.
