If you’re one of the five or so people on the web who haven’t managed to come across strobist.com then I’m officially telling you about it. This blog has a very large and very vocal following and deservedly so.
It’s a “must read” blog if you are interested at all in off camera flash. One of the highlights is Lighting 101, a series of articles that get the reader familiarized with the camera, flash, and flash synchronization methods such as PC cords and Pocket Wizards.
David Hobby, the owner of the site, also has the On Assignment section which shows how he approached making several photographs.
His techniques don’t rely on using very advanced auto-everything flash equipment. Rather, he tends to rely on manual flash with remote operation.
The site is very highly recommended.
