E06 Focus


Listen Later

For this episode, Graham and Nick talk about focus and focusing mechanisms in cameras. Nick asks whether focusing is necessary and Graham talks about one of his favorite Flickr people, ChetBak59 (https://www.flickr.com/photos/129558209@N02) and his use of out-of-focus areas of images to great effect (9:15). Nick challenges Graham to take a photograph where the out-of-focus areas is the point of interest and the in-focus areas are secondary (14:58).

At 16:00 the boys finally get to the definition of focus and how the lens creates this focus on a film plane or sensor. They then talk about the different methods to adjust focus in a camera-lens system (26:41).

They also talk about how focus is verified so we get the result that is expected (38:25).

With all that silliness about focusing complete, talk turns to a camera Graham built over the previous week, the Sixty7 Woody (1:10:30)
