Usually, my camera of choice is my Nikon D300. But, the majority of images here are taken with my little Fujifilm F200EXR, since I need a camera small enough to keep with me at all times. It lives in my back pocket and can come out and be ready to shoot in mere seconds.
Also, I “develop” every image using Adobe’s Lightroom. If you’ve never used it, it’s like iPhoto on steroids. People often ask me how I get such great quality from a little point and shoot camera, and the answer is Lightroom. A little color correction goes a long way.
