Art moves us. Whether it makes us feel joy, sorrow or revulsion, art has the power to affect us and express ideas that transcend rational thought and language. Art communicates these primal experiences not just through an artist's inspiration, but also through very clear, recognizable visual communication techniques. Writing a picture analysis essay requires a basic understanding of essay structure and these visual communication techniques. Excellent picture analysis essays combine both these elements while addressing the more ephemeral ideas and experiences communicated by a picture.
