Remote Capture for Canon PowerShot cameras is a
tool for controlling Canon PowerShot cameras. It
has been tested with the following Canon PowerShot
cameras: S50, A60, A70, A75, A80, A85, A95, A510,
A520, G6, S400, S410, and S500. The main advantage
of Capture compared to gPhoto is that the
consecutive shots are taken without the camera
lenses being closed and opened again. When taking
several thousand shots in a row, this indeed lets
the camera live longer. If you do not need this
feature, gPhoto is sufficient.
