For this project I mounted the camera on a tripod. I used a canon 24mm to 105 mm zoom lens.
Photo 1. F4.0 1/80 sec. Focal lenght 45 mm. The camera is focused on the middle wine glass. The sharp area within the photograph is a narrow band marked in red.

Photo 2. F9.0 1/15 sec. Focal length 45 mm. The band of sharpness is a little larger, however I find it surprising how little there seems in the difference.

Photo 3. F22, 1/2 sec. Focal length 45 mm. The difference between the first and this photo is quite marked. The depth of field here is much greater in this photo than the other two.
