How in the heck can I find out about all of this lighting! How do you know if a camera you're thinking about buying has a lighting system in it, or does wireless, and how can you tell if your flash is compatible with all of the features of the camera (and vice versa)? Likewise, what are all of these things like a flash trigger and receiver, hot shoe adapter, and stuff? Do I need this? What website can I find that will tell me exactly what I need in order to get started in flash? BTW, I know about strobist, but it doesn't really talk about equipment as much as it talks about technique. It'll be awesome once I actually GET my camera and flash.
