That's the fun of post processing. You've taken a picture, now you need to figure out why. Your questions are spot on - what were you really looking at and how do you want to see it?
Add - how do you want others to see it? Frame to the essential(s), or place what you saw in a broader context and let the viewer discover for themselves? Lead the view with burning, dodging, vignetting, WB choices, etc., or leave it 'straight' and rely on the strength of the elements?
My frustrations are:
- the shot was taken with some nebulous 'other' viewer in mind, and bores me;
- I find what I wanted to see, but I was stupid at the time of capture and didn't place myself in the right place to make a good picture of it;
- my technique was sloppy (focus, exposure, DOF,), and I don't have the ingredients to make a picture of what I saw in the way I wanted it to be.
