You're welcome, Apple_UK.

Please understand - few people seem to - that when you decide to change your methods to linearising colours before processing, then gamma-correcting afterward (in Poser 5-6-7-8, this can be done in the material room by adding a set of nodes; in PoserPro, you just tick a box, I think), you need to adjust your lights as well. There's another thread that goes to some length explaining why the poster has decided not to use gamma-correction and has posted images to show why. His lights were not adjusted at all, reflecting a complete lack of understanding about the whole process.

I cannot explain in as great a detail as BB did about how the whole gamma-correction process works and why your lights need to be scaled down after applying it: he's gone on exhaustively on the subject in a far clearer, better illustrated fashion than I could ever do. Just do a search on the Poser forum on "gamma" and user "bagginsbill".
