I wanted to do a little experimenting with 2nd curtain flash sync, so i set up a teddy bear in the sun room and did some portraits, some with 1st curtain sync and some with 2nd. I compared the results in DPP, using the "info" box to show me which photo was made with which curtain. No problems. Then I left the camera in 2nd curtain sync (intentionally) and did some shots of my wife but when I checked the results in DPP, all the shots showed to have been made with 1st curtain sync. I thought, man, that was careless, but when I checked the camera it was still set to 2nd curtain, the way I left it. So I just scratched my head and wondered what had happened.
Today I went out to do some playing with 2nd curtain sync and leaves blowing in the breeze.When I checked the shots, DPP showed all of them to have been made in 1st curtain. Like before, I check the camera and it's still set to 2nd curtain. At this point I'm sure the camera's acting up, so I just fired off 2 shots, one set to 1st curtain and the next to 2nd curtain, because I'm sure they're both going to show 1st curtain, but they didn't. The one I shot set to 1st curtain showed that way, and the one I shot set to 2nd curtain showed that way.
Has anybody heard of this?
