Bokeh. A definitive guide to some of the most fascinating effects in photography.

This video is a comprehensive study of bokeh – and the main ingredients that go into producing good (and bad) bokeh in photographs. With tests and demonstrations using many different vintage lenses.

It’s based on many years of observing how different lenses produce different styles of bokeh. And it brings together many different factors that influence how bokeh looks in any given scene. My overall conclusion is that producing a great bokeh photo involves so much more than using the best/fastest lens.

I cover a lot of ground, so if you’d prefer to go to specific parts of the discussion, here subject time links:
