it's necessary to buy PP2010, as poser 8 is already obsolete and has tone mapping
(instead of GC).  tone-mapping (exposure control), whilst familiar to photoshop users,
has never been explained adequately in re: poser IMVHO.  it's like GC is the 8-bit,
1990s version of TM.  if more folks learnt how to use it, it would have really caught on.
