It’s what you look for and what you see. If it was just what you see you’d go blind to your surroundings. If it was just what you looked for you’d miss the subtle differences you see by focusing.
Observation is the practice of zooming in and zooming out. Your eyes write stories and etch memories with every sight. No person’s vision is exactly the same. Perspective is a singular experience in which everyone sees different things.
What’s obtuse for you may appear obvious and normal to other people. And vice versa. But vision is ultimately social. People have to agree on the same things. So we drive on the right side of the road and define cats versus dogs. What you see is what you get, but that doesn’t mean you always have to agree.
