I thought this picture of explorers from National geographic was particularly interesting and many features and characteristics we talked about were present. Right from looking at the picture you notice the attention to the depth of field. The distance between the boat and the mountain in the background is really muted because of the angle the photo is taken. The picture also has a blueish tint background color, which is from the use of white balance to adjust the neutral colors. The mountain gives off a nice symmetry with the body of water to give it a nice mirroring image. The main style incorporated is the rule of third. The photo chooses to position the focal points in a way to create a strong composition for the mountain in the background and as well for the people on the boat as well.
