Photography
Evocative photography requires awareness of light, color, composition and (ideally) thorough knowledge of the subject. That said the best photos often happen when you least expect them and are gone in the blink of an eye, if you don't capture them. Understanding of aperture, focal length, exposure and media allow even more flexibility in how your camera interprets what is actually there but they are no replacement for trusting your fundamental intuition and instinct.
