In my photography class this week, I told my students that when shooting flowers, they should always try to get a different point of view than the straight down view that we always see when passing a flower on the sidewalk. I'm always giving them rules to follow, with several good cases why they should follow it.
So much for rules.
Nikon D90, 18-200mm VR lens @ 200mm, f/9.0, 1/80s, ISO 200. Racking the lens out to it's longest focal length and standing close to the subject still allows a fairly shallow depth of field, even though the aperture is fairly wide at f/9.0. Also, this lens suffers from lens creep very badly; that is, when it's pointing downward gravity always extends it to it's longest focal length if left unchecked. Not bad when you're breaking rules, anyway.
