Talea Feet Lying Down

A small aperture would siginificantly increase the depth of field here. Putting her feet at the hyperfocal distance would keep the whole body in focus. With an 18 mm lens, at f/13, the hyperfocal length is about .5 m. So if the feet are at .5 m, the rest of the body will stay in focus.

With all due respect to Mr. Phelps, (an artist that I admire) I must question his advice. Does the entire figure really NEED to be in focus? I think not. The very narrow DOF, combined with the grain, makes for an effective perspective.
