Sometimes the image captured isn't what you expected given the refresh rate, especially if either you or the subject is moving. Buy an 8 pack of batteries and experiment with taking a variety of images under different lighting conditions and types of subject matter. You'll be better able to determine the outcome if you have a good idea how your camera will behave. Additionally, I find it's very hard to take a bad digital image. If you're disappointed with an image, try cropping.
Horizontal images can become vertical and vice versa.
I prefer the panoramic format, as it enables a more dynamic relationship between elements within the image frame. Many digital cameras come bundled with decent photo editing software. Save a copy of the original image, then experiment. We understand you're working on a Java based project with some folks in San Francisco. While Jezebel allows me the freedom of complete control, there are opportunities working within a team that I find far more enriching.
