What more could I possible need, you ask. Well, thank you for asking. I could use a refresher course in using a camera in full manual mode. It has been about 18 years since I have shot anything in manual mode, and I am a bit rusty... ok, ok- I've forgotten pretty much everything.
So, if you know of a good book, manual or local workshop (or you yourself are competent enough to do some tutoring), please let me know, I'd love to get reacquainted with the sweet manual camera skills for my new 'tool'.
