As to exposure, sometimes I intentionally underexpose. For M9, using ISO 640 and add 2 stops in pp results in less noise than using ISO 2500! Once in a while, i do bracketing and stack the shots to make an HDR photo.
We all tweak the curve a little due to the nature of digital sensors. We all try our best to use as much of a relatively narrow dynamic range as possible, balancing contrast with details. Fine-tuning the curve is the best way to achieve this.
As to color, we all know the limitation of digital sensors. White balance is rarely correct out of the box, so fine-tuning is a must. As to individual color channels, I sometimes try to adjust away obviously ugly hues. As I often take portraits, I also have to make sure that skin tone is not totally out of whack!
A more difficult challenge is in dealing with the inherent limitation of a lens. This problem comes up when I absolutely need across-the-frame consistency in a shot. This means I have to deal with vignetting, loss of contrast and details at the edges, and uneven noise at the same time! It is difficult work but once I get it right I find it very satisfying!
There are other reasons I do pp. I'll share them later.
I really don't think what I do turns me into a cheat, becoz all these things are part of my normal workflow, which doesn't stop at the click of the shutter. Technique wise, I am very much influenced by Ansel Adams. I try to learn from him and adapt his techniques to digital photography.
