^ This photo is using the photography rule leading lines. It's using leading lines with the lanes on the track the lines help capture the moment and whats really going on. They are all racing for first place and without the lines being there and the photographer not capturing that we wouldn't know that.
^ This photo is using the rule simplicity. The photographer captured the man speaking with the clear blue sky as its background. The speaker is obviously an important person and the only thing the photographer wanted to focus on
^ This photo is using the rule of creating depth. The photographer did this by using the bushes all around in the photo. The photographer used it far away, and also up close, creating a three dimensional picture.
^ This photo is using the rule framing. The photographer used the crowd to frame the main subject of the photo which is the dog. By using framing it shows what's actually happening. The dog is running or maybe even racing as the crowd (the frame) cheers him on.
