Quote - What's 'linear data'
I should have said "linear colour data" perhaps, but since Poser sees colour as numbers, it's just data to me.
BagginsBill explains it best, but I'll have a go. In order to be able to view images on our monitors and so forth, something called gamma-correction has been applied to the colour (and shades of grey). This includes actually any colours you see on your monitor, not only images. Poser requires uncorrected (un-gamma-corrected) colour information in order to process colours correctly. Un-gamma-corrected colour is linear colour data.
After Poser has finished processing (like in a Diffuse() node) then you have to gamma-correct those colours again in order for them to display properly.
Whether or not gamma-correctly leads to great art is not the point. It's about colour accuracy, not great artwork.
