Digital BW, The Print

I am new to Photoshop 6.0 and would like to find a good book that is 
aimed at someone who is a photographer and not a graphic designer. 
Since I know very little about PS the book I am looking for would 
teach me the basics and work up from there.

Also can you suggest any other books that would be good for someone 
who will only use PS 6.0 to print B&W?

BTW one thing that I am very interested in doing is making digital 
negatives. 


Thanks
