Its "Understanding Shutter Speed", and yes, it is great. I've been into photography seriously, since 1967, when I got my Pentax Spotmatic, so I thought I had a pretty good grasp of the subject. Even after all this time, I learned a few things from both "Understanding Exposure" and "Understanding Shutter Speed".
Peterson also has another good book called "Learning to See Creatively". This is a subject that is difficult to teach, but he has some good techniques for bringing out whatever creative talent you may possess.
