We are about to switch to a new forum software. Until then we have removed the registration on this forum.
Ok, my question already was made in the processing forum in 2007 but nobody gave a concrete answer, so I'll repost it here but with some minor changes.
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?
Ok, I'm looking for the same thing: how to control a digital SLR to take long-exposure photographs.
However, I would be satisfied if I could do this just with the normal built-in camera or any external usb camera. My need is to take long exposure photographs and save that in specific files in the hard drive.
Well, any guidance would be wonderful! (:
Thanks for your attention!
