You're no different than the rest of us, Gareth. Post-processing is necessary particularly in situations where initial lighting isn't ideal or the camera's white balance is inadequate. Even when manually set, WB can change as your camera angle changes and more light hits the sensor or a nearby colored surface. I can understand the requisite that post-processing be limited to cropping and resizing in order to prevent less than scrupulous shutterbugs from enhancing colors, but it takes a lot of my own pictures out of the running (not that I'd enter) since I use Photoshop to correct my camera's minor mistakes. It's the digital equivalent of darkroom processing, but considerably more powerful and thus dangerous if not used properly.
