Part of being on your game, just as having focus zone set, knowing which way to turn the lens, choosing focal length, angle of view, -- all tools.
A bit of simplicity in isolation-- I do not care for many "busy" backgrounds with bright areas to draw the eye somewhere distracting to the image you want.
Some days it just seems you see all of this with the right subjects, and then there are the others, and the circle of confusion includes everything.
Often a disappointment when you cannot get position, or your equipment lets you down.
