I, too, started out doing exclusively 3-D work.  My first posts here were in the Blender gallery.  I quickly discovered the 2-D gallery, then the writer's gallery, and finally photography.  I'd posted some photographs in 2-D in order to show something I'd created in "real life," but this is the first image I posted in the photography gallery.  This is my first image that was a photograph for photography's sake.  Aside from darkening a busy background, there was NO postwork here.  I could barely open Photoshop by myself at the time!  This is a great idea for a forum thread, Bruce.  Thanks!
