Yes sir, there is a Gama node, and there is a script to change Gamma too.
Who ever said Poser was not full of options..... :-)

Use a single infine light at reduced setting in BB's shere, and soften your light shadow a bit.
This should get you in the right direction.

By doing small steps, one can climb a hill.
