Project 2;Focus with set aperture

In the course notes it suggests that this project be done in the field. I have chosen to use a still life instead.

Photo 1. F 4.0, 105 mm, 0.6 sec. Camera on tripod. Focus sharply on foreground.

Photo 2. F 4.0, 105 mm, 0.6 sec. Camera on tripod. Focus on the middle of shot.

Photo 3. F 4.0, 105 mm, 0.6 sec. Camera on tripod. Focus on back of shot. Fore and mid ground are blurred.

I think I prefer the third photo. What I prefer about it is that the eye is led into the picture from the foreground.
