"Have you ever wanted to modify the operation of your camera? Do you want to automate repetitive tasks, or just customize the camera to your own style of shooting? Well, here's your chance! DigitaScript is a plain text command language that lets you control many of the functions of your Digita-enabled camera. Some of the tasks you can script your camera to perform include: 

Controlling the color balance, bracketing, and exposure parameters. Controlling the placement of watermarks and logos in your images. Prompting the capture of specific images.

Using DigitaScripts, you can customize and personalize many of the functions of  your Digita-enabled camera. DigitaScripts also make it possible for your Digita-enabled camera to build web pages automatically, guide the camera user to capture specific images, build databases with images, sound, and text, and more."
