    That is an abnormally bright tree, I don't think I've ever seen one like it before.

    I'm just starting to really play around with RAW, I'm no expert yet. Basically it allows the camera to store the raw (as in unprocessed) data directly from the camera's sensor for manual processing later on a computer, instead of automatically in the camera. A lot of data is lost when the camera processes the photo and creates a JPEG (or JPG) image. A JPEG can only store 8 bits per colour channel (red, green, and blue) where most cameras store 12 or 14 bits in RAW mode. This gives you more control over colour corrections and allows you to retrieve details in very dark or light areas of photos. RAW files are not easily readable by most imaging software, every camera has it's own, non-standard format. Perhaps because every camera's sensor is different. So you need special software to process the RAW data and convert it to something that's more easily readable. This makes processing much more customizable, you're not locked in to the limited settings in the camera. You can even change things that were set in the camera, like white balance, picture style, you can even get the colour back if you shot in black and white.

    Here's the wikipedia article for more information if you're interested:
