I recently used a tripod and remote shooter release (cable) with my Panasonic GH3 outdoors to still a waterfall, and everything worked fine. Then I moved indoors and set it all up again but couldn't get the remote to work. I changed the settings (M,S,A,P) but still nothing except for a faint flicker on Live View. I switched the camera off and tried again. No luck. I changed the memory card and I pulled the cable out and reinserted it. No luck, so I gave up. Since then, the remote has worked well. What possible reasons could have caused this?
The remote is a RM-L1-PSI made in Taiwan.
