When one’s work is equal to one’s judgment, that is a bad sign for one’s judgment; and when one’s work surpasses one’s judgment, that is worse. As happens when a photographer is amazed at having done so well; and when judgment exceeds the work, that is a very good omen and a person so endowed will without a doubt produce excellent work. He will compose few works but they will be of the kind to make others stop and contemplate such perfection with admiration.

Adapted form the writings of Leonardo DaVinci.

Human vision has one extraordinary ability that a photographer cannot take for granted. It can perfectly focus on two separate images as seen by two eyes, each from a slightly different angle, and marry them into one single picture.

Such binocular vision is the key to how we perceive shape, form and depth; and it cannot be duplicated in photography. With limitation of monocular vision, photography reduces an image to a two dimensional form—the flat surface of the paper combined with only the appearance of depth within the image.
