Insect and DOF
These are two shots of a small Praying Mantis on an off-white stucco wall, in shadow. The insect was about 3/4 of an inch long and was the color of dry weeds.
I posted these to demonstrate depth of field and to show that you can take macro shots without spending a fortune on lenses.
They were taken in natural light with a Nikon D300 at ISO400, F13 and the lens allowed to autofocus.
You’ll notice that the bottom shot, while far from the perfect mantis pose is a much better angle, but the wrong end of the critter is in focus.
This is the reason I prefer to manually focus macro shots.
These shots have been resized and the top picture has been rotated, but are otherwise untouched.

Hand held 24-120mm Nikkor -120mm ISO400 1/640 F13 sRGB 300dpi
After looking at these shots, because the subject was relatively stationary, I should have shot raw instead of JPG, used a monopod to allow a setting of F32, ISO100, and used a matte reflector to make the light more interesting.

FWIW: This is the result of opening the bottom picture in Corel Paint Shop Pro Photo X2 and clicking Smart Photo Fix.
