Perception Deception

A very interesting understanding..

How could shadows go in different directions? Isn't this proof that the lighting is artificial and that the picture is a hoax? No, and people who say such things would know better if they had a basic understanding of perspective.

Go to the park on a sunny day late in the afternoon when the shadows will be long and look at the shadows from the trees, light poles, and other tall objects. Move around and look at them from different perspectives. What you will find is that the only time the shadows are parallel to one another is when you line yourself up with the light source (the sun) and the objects you are looking at. Otherwise, the angles of the shadows will fall in a variety of ways.

Perception is a complex process by which the brain constructs visual, auditory, etc. perceptions that may or may not have anything to do with what is actually out there in the world beyond the superficies of our bodies. As psychologist Jim Alcock notes: “Our brains are also capable of generating wonderful and fantastic perceptual experiences for which we are rarely prepared. Out-of-body experiences (OBEs), hallucinations, near-death experiences (NDEs), peak experiences….” Not being prepared, we may believe that the profound effect they have on us requires some sort of extraordinary explanation involving transcendent reality. But often what we think is going on outside the body is actually going on inside the brain.

  1. Beautifully put. Perception is complex and it’s hard to know which one is right, our perception towards things changes every time. For example reading a book or studying for an exam once would never be enough to our understanding that’s is why most of us choose last minute revision, or like to go over material over and over, because every time we read information in our mind is registered and stored deeper allowing us to have a better understanding.
