All these 8 photographs were take by Ansel Easton Adams, who was an American photographer and environmentalist. His black-white landscape of American west are very famous until now. Before these I never compared the black-white and color which one better. But now I think sometimes black and white is better than color. Because black and one could be any color, once we see these black and white photographs every one of us could imagine to different color. The last two are same location. But they give me different feelings. The black white one give me a clearer vision than the color one. it creative a calm and comfortable mood.
