Macro is not only one of my favorites, but a really good choice of photography . It's used when you want to capture something that nobody ever pays attention to . When your camera is set to macro it blurs everything except the emphasis .
Leading lines are basically like a mad leading you to either the emphasis of the picture or to make you see further into the picture. With leading lines the viewer shouldn't be searching all around the picture trying to find the point of it.
The Rule of Thirds is when you take the emphasis of the picture and move it over so that it has more depth. To get to the rule of thirds, the frame is broken into three blocks going vertically and horizontally. The emphasis goes in the intersection of the lines .
