100% in camera (except RAW conversion and setting the black point). Camera movement - vertical pan.
I'm judging in a few weeks at a camera club competition that has two basic categories - straight and altered. When they sent the club's competition rules, I was surprised to see that images created by moving the camera had to be entered in the altered category together with Photoshop "digital art work". This was also true for multiple exposures. They're their rules and I have no problem judging by them but don't totally understand the logic. Sure cuts down on in-camera CREATVITY which, when I'm judging, is the thing that separates pretty pictures from winners. I use the "4-C's" - Craftsmanship, Composition, Creativity and Communication in that order - and expect the winners to be more than an ordinary image of an extraordinary subject as I'm judging photography and not a beauty contest. (Have you noticed that an *ordinary* image of a pretty girl will win 9 times out of ten over an *extraordinary* image of an ugly man? Hey, folks, it's about photography first and the subject second.)
