Before this unit, I had never considered the way a picture captures an instant in time and preserves it so you can look back on both good and bad. The more I think about it the more I realize that a picture is like a time capsule, something for the future to look back on and wonder why we did the things we did. You can tell so much about a person just by looking at a picture. Personality shines through each picture taken of someone, even the camera shy.
