How often do you crop?

I understand what you're saying and the key phrase here is 'minimum amount necessary.'

Most of my cropping is forced upon me by the restrictions inherent in a 3:2 sensor (or a 4:3). Some shots look great with one aspect ratio but not with another. Other times I need to crop due to paper dimensions and frame considerations. Occasionally - I'll freely admit - I find a small but spectacular feature in an image that just begs to be up-sized and cropped. I can do this with a 36-mP D800E with perhaps too much ease, so I try to discipline myself when shooting to use my glass to the best advantage in the first place.

My point is that cropping is often a necessary compromise and sometimes provides an enhancement to the composition of an image. It should be used judiciously but should not be considered something that is best avoided.
