Having been on a couple of photo shoots with Marc Horovitz, one tip I can
give that makes a world of difference is to get a pinhole aperture for your
camera. This is a really tiny hole in a sheet of shim stock that gives you
something like f/96 or f/120. The effect of using this is that the depth of field
is practically infinite, so you don't get the front of a locomotive sharp while
everything from the air pump back is out of focus. It also allows you to get
extremely close with that huge depth of field. Shoot low with a pinhole
aperture and you will get an extremely realistic-looking photograph.
