Sometimes, things "try" looking up...
when they're forced to look down.

This is one of the tulips in the previous shot...
I thought it was really neat how the upside down petals literally began to move
and curl "up", as if trying to look away from the strong light source beneath them.
A piece of black poster board was placed below and behind the bloom.
A single, halogen desk lamp was used below the bloom for trans-illumination.
A piece of white paper was positioned to reflect
some light back onto the top of the flower too.
