In recent years I've become frustrated with composition. First, I don't think my eye is as good as it was twenty years ago, second, I find many photographs to be formulaic, mine included. While I get a much higher hit rate of good shots through the viewfinder, the really exciting ones are generally from the hip, chest, arm's length, but rarely the eye. I don't mean blasting away blindly, but liberating myself from the tyranny of the frame and my expectations of composition by 'feeling' for the shot rather than putting it in harness to my expectations. The decisive moment seems to be a combination of control and happenstance.
Technically I'm confident enough in exposure many years' experience to know how the image will print.
