On being one's own harshest critic ...
I tend to label myself as a recovering perfectionist. I think I'm mislabeling myself. I got a new camera last week - on Wednesday to be exact. I tried out the camera with it's IS USM lens on a relatively stationary subject - my cat Sprite. I had some issues with the AutoFocus but that was quickly resolved. My next test situation was Friday - low light, moving subjects. On Friday I shot 204 photos. The first dozen or so, I was trying to get the Aperture, ISO, and White Balance settings tuned. I hadn't fully read the manual so one key feature that I really needed but didn't discover until today was the illumination for the controls. I was literally shooting in the dark for the first dozen photos and accidentally set the White Balance to Shade rather than Tungsten (big difference!). I was becoming very frustrated that the shots weren't as good as those I'd taken with the Kodak DC4800. Luckily I was able to take test shots of the first band and then retreat the back...
