Digital BW, The Print

The essential tool is built into the digital camera I use and is called 
a histogram! 

I use it all the time, and I think it will remain the only way to get 
optimum exposure. Incidentally I think Nikon have tweaked their 
auto-exposure system to give better results from digital, certainly my 
experience suggests that the D70 is an improvement in this respect on 
the D100.
