 <color #ed1c24>WARNING!!!!</color> If you came to this page without looking at the [[live_capture_setup|Live Capture Setup]] page, then shame on you!

+<color #ff7f27>It seems</color> <color #22b14c>gphoto2</color> <color #ff7f27>has an issue if the shutter speed is slow. So using a shutter speed of say 1/250, then I can capture and download a file. If I use a shutter speed of say 3s, then I can capture, but download simply won't happen.</color>

+On the 700D, 1/6 seems to be the cut off, if you go to 1/4, then you lose the ability to capture and download in a single command. You can of course capture, execute a wait equivalent to the shutter speed (plus a bit for writing to the card) then do a download using the <color #ed1c24>--skip-existing</color> so you only download files that have not already been backed up.
