I've been copying 100s of prints with my 600D connected to a laptop. Allowing the software to wait a few seconds for me to change the print (On a target frame) then taking a photo, then repeat automatically.
I tried it a few days ago, I tried it and the I wasn't able to set the 'gap' time or shoot photos with the button. I think I've forgotten how to do it, not sure.
Can anyone point me back on track please?
