How to take very easy macro images with a Canon EOS 40D.
Step 1: The Lens
use the lens which can focus the closest that you have.
Step 2: Set the Dial to "AV"
Step 6: Snapping! :)
Set the self timer to 2 seconds, put your camera on a tripod, aim, focus and press the shutter button. (warning do not touch the camera while is takes the photo, camera shake does NOT look good at all!!!
