Digital BW, The Print

I usually do extreme adjustments to my images, with multiple sets of masked
curve adjustment layers. 

Starting with an 8bit file and adding all the adjustment layers I've seen
very bad posterization. Converting the 8bit image to 16bit and adding the
same adjustments solved the posterization. Huge difference.

I reccommend doing all adjustments in layers. Then it's very easy to convert
without redoing the whole file.
