Can you see the face? I saw this sunflower the other day and had to take its picture. Due to the way the sun was illuminating the flower and the shadows that were created at that moment, you can see the shape of a face in it. You have to take a few steps away from your computer and look at it from a distance to see that face. Cool! isn't it? That is why shadows are important. They define. Had the flower been illuminated with a flash from the front, you wouldn't be able to see that.
