Have you noticed how smear helps creating art...? In all kinds of art, there's a kind of inertia or smoothness... for example the way clay behaves, so you can't have a very sharp edge. And in painting, the materials do that again, the way the pigments run into each other ever so slightly, or how you can only get a limited sharpness with your brushes or palette knives. Or in photography, where chemicals behave that way, or the way photo sensors behave... or the way you can only have light with that much contrast. And in music, subtle features like distortions and echo or reverberation create smear. But even the reaction of electronic components do that, they have a given reaction time... don't laugh, I just read about slew rate! But it doesn't have to be art in the strictest sense. When driving cars, you can't instantly turn from one direction to the other, there's a certain smoothness, a reaction time, a transition between states... And this ever present smear washes things together and results in a smooth product, it encourages the mind to find meaning in the undefinitely presented, smeared information, instead of showing things directly. In the end, the mind creates art. I was thinking, we are going towards less and less smear, things are getting clearer and losing smoothness... is this because our minds are getting quicker? Or it's just the minds of the inventors, and the rest of the people can't follow it? What is the natural smear of things that makes you feel "ah it's good, this is the right amount"?
