The tripod plate I use to connect and secure my camera to my tripod is actually stuck on the base of my camera. I've tried twisting the siver ring that I'd normally use to loosen it and the ring has actually come off. What do I do? I feel like it's too dangerous to twist the plate as hard as I can and wish for the best. Or use a screw driver on the D ring to force a twist on the thing. Someone else.
