The three point perspective for photo composition is achieved when you are at a low angle from the subject. It creates a slight vertigo effect because of the converging verticals, yet at the same time you have the other two side point perspective to add greater depth to the picture.

You will need to get low to get the angle for this three point perspective viewpoint to work. Making this perspective to work requires a bit of an unusual angle from the subject. Too far and your image will look like a two point perspective, and too near you will only get converging angles and you may not be able to cover the entire subject properly into your picture frame, unless of course you just want to selectively shoot a portion of the subject.
