camera techniques

I watched a few video in BBT today and they were talking about camera techniques. I think we watch the videos because we are going to take pictures sometime this week.In one video it was telling us about what angle we should take a picture and it looks a lot better when took the picture like that. In the videos I didn't find anything really confusing, there was a few things that were but most of it was easy to follow. There are a few things I would like to know more about, but I did understand most of the things they were saying
