Hello,

I have a couple of newbie questions concerning digital still camera control in processing:

1) Is it possible to trigger a camera's shutter from processing? via USB?

2) Most cameras automatically go into "memory" mode when connected to a computer via USB (i.e. camera's memory mounted as a drive). Is it possible to control the camera mode so that one could  switch between "camera" and "memory" modes?

Basically, I'm using a digital SLR camera to take hi-resolution long exposure photographs, and need a way to BOTH trigger shots, and move image files from the camera's memory to a hard drive.

I'm hoping to avoid video capture altogether since I don't want to deal with mocking up a long exposure-like effect. Not to mention there would probably be image resolution limitations(?).

Has anyone had success doing something similar? Are there any specific cameras out there known to be easy to work with remotely?

Any help/advice would be greatly appreciated!!

Many thanks,

daniel
