Composition

 Rule of Thirds:

This photo is an example of the rule of thirds. The photographer used this technique effectively because your eyes are drawn to the dog and kept there. In addition to the rule of thirds, they also used contrast, as the black dog and the green grass are very different, making the dog pop out of the picture.

Fill The Frame:

This photo is an example of fill the frame photography. It is a great picture and the photographer used this technique to his advantage. He must have either zoomed in close, or taken the picture close up  to capture this. The way the light glimmers off the drops of dew is very appealing. 

Use Of Lines

This picture is an example of using lines effectively. To do so, the photographer must have stood on his knees and held the camera at an angle. This is really a great photo because the lines lead to the main subject of the photo; the hand that is playing the guitar. The focus being only on the hand makes it clear that the main subject is the hand.
