Digital Cameras

Does anyone know how to write code to snap a digital camera (take a picture) from a java application? Can code be written to "see" what the camera sees in the Java app and then actually snap the camera. I know there are TWAIN packages to retrieve pictures from a camera's memory. I actually want to snap the picture from the Java app. Does anyone know how to do this? Any tips or suggestions will be helpful

Thanks,

That would all depend on the camera.
Some (typically the most expensive professional models) do indeed support remote control like that but it's typically achieved using custom software (or maybe a Photoshop plugin is available for it).
You'll have to contact your camera manufacturer to ask for details, and the job will likely require a lot of JNI code.
