I have an old A650IS that I recently used to take pictures of the solar eclipse. The pictures came out much better than I anticipated which reactivated my interest in installing CHDK and see how far I really can push this camera... I have installed CHDK on the sdcard and know how to upload it to the camera for the ongoing session.
I would now like to be able to remote control the camera over USB from a Linux laptop. Reading the information it seems that with a standard USB cable between the camera and the laptop I should be able to script chkdkptp or ptpcam to do pretty much "anything". Would that be a fair statement?
