I usually associate 'perspective' with leading lines, but here is an example I did years ago using 2 different lenses and changing distance-to-subject to get 4 unique images.
Hopefully I can put on my thinking lens and go out a create something new for the Challenge. I replaced my stolen D-70 with a D-40 (couldn't wait for the D-4) along with a 55-300 VR lens. Stay tuned.
