Digital BW, The Print

Back in the old days (2years ago). I sent out a 35mm B&W neg for a 
test scan to a photo shop. I asked for a "Black & White scan", I was 
very digital literate then. I got back an 18meg tif. It was 8bit 
mono.

Remember, I was dumber then. I adjusted probably about 30 different 
selections levels, end points/midpoints - everything - all in 8bit 
mono. Then I thought, now I want this sepia, converted to RGB 8bit 
and put some sepia in, sent it of for lightjetting to 24" wide. 
PRESTO - Posterization. 

I told the sales guy that I didn't like his scanner, it "banded.

So there we go, my 8bits worth (oh no)

Anyone know why they have 12bits in slr digitals? Is it a (4)bit 
better (oh no no no!)
