This was taken
with a 20mm lens at my old work (don't you love my office?) The colored
bit around the lightswitch is what was covered by the 300mm lens. Yes,
that's a wookie.
Both these
pictures were scanned at the same resolution, and both are the full
frame. I put the "Escape from L.A." postcard on the lightswitch to
see if anyone would notice, and it sat there for 5 months before anyone
said anything.
