[Frameworks] Timelapse and camera shutter/mirror jam

[Andrew Connor]

Hi Roger,

Thanks for the advice - I wondered about the intervalometer, but I've 
also checked the camera by taking a lot of shots in quick succession, 
and it's still happening when I do that, so I think it's definitely the 
camera that's the issue.

Thanks,

Andy
