I came across a podcast recently that I think will be of great interest to many of you, it's call "The Art of Photography" hosted by Ted Forbes.
The Art of Photography will be of interest to the novice and professional alike, here is just a few of the topics covered in the 67 videos:
ISO
Aperture
Shutter Speed
Lighting (parts one, two, and three)
Shooting Tethered
Framing on a Budget
Choosing the Right Lens
Promoting Your Work Online
You'll also find interviews (with folks like Annie Leibovitz), book reviews, and something you don't find very often, working with film (developing, working in a dark room, and more).
Ted really covers each subject quite well and the videos are only seven to ten minutes long so it's really easy to squeeze one or two into even the busiest of schedules.
So head over to The Art of Photography, once you see what they have to offer I am sure you'll want to add them to your favorites and while you're there you can watch videos right on their website, subscribe to them via iTunes, or download the videos to watch at a time that is most convenient to you.
You just can't have too many good photography resources.
