The greatest challenge I have with creating art with my macro lens is a technical challenge - focus.
When shooting in macro, the depth of field afforded with the camera's aperture settings is minimal, at best.
So when shooting photographs in macro, it is crucial to use as much depth of field as you can muster. Though you are generally looking to create images with a very tight, very limited amount of depth, this is something that makes all the difference in macro.
This photograph is another in the series that Teresa and I shot awhile back at Fossil Creek.
A flower, yes. A very odd looking flower. It almost appears to be alive, like some sort of alien getting ready to bite the head off its viewer.
