Automating multiple auto-timed AEB shots?

[HiFiGuy1]

I was taking my first foray into HDR last week and did something I haven't been able to duplicate. I wanted to take 7 shots at 1 EV intervals in order to give more gradient for the Essentials HDR software to use, instead of the three that normally come with AEB on my camera. I have a 40D, which I set to 2 second timer.I set AEB to +1,0,-1. I set the EC to -2 EV. I then carefully released the shutter timer, and to my surprise, it took all three shots by itself in quick succession after the timer counted down.


I tried to do the same thing, as best I could remember, for the same shot with EC set to +2 EV. This time, I didn't get the three quick shots, but instead had to release each one individually. I still used the timer each time. Since it didn't work, I carefully re-checked the settings to make sure the settings were the same, without disturbing the camera any more than necessary, but couldn't duplicate the behavior again.


I did not change the setting for the timer between shots, as far as I know. Any guesses why this happened once but not the next time? I would like to duplicate thisbehavior if possible.

Anybody?

Why won't you just check your manual?

Did you notice the part about the disparity in behavior? That probably isn't in the manual. []


I will look in the manualfor how it should behave, though. Thanks for the suggestion....
