People, animals, and even inanimate objects change over time. But if you see them regularly, spotting the differences isn’t all that easy. Day in and day out, even over many years, they look much the same to you. But by comparing photos, the things our eyes perceive as subtle suddenly become significant.

For instance, have you ever had a friend you hadn’t seen in 15 years? Then, you go to visit, and you can’t believe just how different they look. Or perhaps you go back to a lake you fished at while a child but now as an adult, there are big changes. The landscape isn’t all that familiar due to mature trees and a shifting shoreline.

These 66 photos are perfect examples of just how much people, animals, and things transform over the years. We hope you enjoy.
