Everything that we see is not reality. The photograph that I have selected looks like a giant hand with a little person hanging on to the pinky. While this is a picture of an actual hand. and also a picture of an actual person, the photograph has either been manipulated or the perspective skewed in such a way that we have to do a double take (look more than once) to determine that this photograph does not represent reality.  We know that there are no giant hands and that there are not people that small, especially in relationship to the hand. However, it is quite amusing to look at this picture and appreciate the novelty of the shot and how a photograph can actually take real elements and portray them in a realistic way, but still lead our eyes to fool us and our minds to have to think twice saying: could this actually happen!
