By introducing the works of photography master Henri Cartier-Bresson, it can be explained that good composition can make a photo have many levels of highlights. Lighting, like shooting timing, picture composition, and content depth, is just one layer of highlights, not all the elements of a photo. A thoughtful photographer should break away from the "flashy but hollow" style and return to the path of enriching the content of the photos. The more appropriate highlight levels a photo can show, the more perfect the photo will be.
