If you've had the experience of painting a picture, you know that there is much to think about as you're working on it. You see something, then you try to express what it looks like, or maybe what you feel when you look at it. Let's say it's a barn in your grandfather's field. You can choose to paint it in shades of red or maybe just shades of gray. You can make it look much bigger than it actually is in the field. You can have it bending with the grass, or maybe your picture will show horses and cows flying out of the windows. You can show the barn as sweet and nice, making it as pretty as a picture (like a photograph taken on a clear sunny day). Or you might represent it as a person that's fierce, showing hard angles, and maybe a raging storm in the background. Whatever way you paint your picture will relate to the mood you are trying to convey, to the feeling you are trying to get across to the observer.
