A Little Science

Depth of Field.....  There is really only one screw in focus in this picture. That is a result of a very shallow depth of field. A telephoto focal length of 250mm and a fairly wide aperture of 6.7 results in a very shallow depth of field. In fact, it is less than 1/100 of an inch.

Nikon D610, 1/125 second at f/6.7, 250mm (28-300 f3.5-5.6) - 2638
