I took over a hundred shots in about an hour of this tulip opening. Of course I couldn't use all of them this much is a heavy load as it is.
I found it interesting that about half way through the shots when I turned on some music the scene developed
a rosy glow around it for a few minutes (which I couldn't see visibly) and the Tulip started to close back up.
I used a tripod and a remote control There shouldn't have been any jerking because there was
no camera movement. I have no idea why there is.
