What are your favorite photography education websites (other than the allmighty TPF of course)? I really want to learn as much as I can about actual photography without having to take a class. I just don't have the time or cash right now for a class I don't need for my degree. I know very little like I understand Aperature, Shutter speed, and ISO, but thats about it lol. I would really like to understand filters and lenses better, but I dont want to narrow the criteria to just that.
