Here is a shot that has sold a number of times as a stock photo. Was shot with a 4×5 view camera on tungsten transparency film. Used 3 Arri fresnel lights for lighting. One had a light blue gel to light the front of the hammer and give the metal a cold look. Had another with a yellow/orange gel on the background to warm it up. And one more light with no filtration for fill light on the side of the hammer.
The shallow depth of field was a combination of a near wide open lens aperture and moving the lens standards in opposite ways to achieve the desired result. With photographs like this I am trying to get more of an illustrative look than literal and leaving the picture open to interpretation by the viewer.
