AEB bracketing question

jedasa

I set up my T2i for the first time to try AEB with continuous shooting, AV priority, +- 2 EV, as per Canon manual. I was expecting to get three separate photos per shot. However, when I downloaded the photos with ZoomBrowser there was only a single photo (actually two because I shoot in RAW/jpeg). The thumbnails in ZoomBrowser show however a tiny icon in the corner showing three layers - which I've never noticed before. So it seems like the three exposures for each photo have been joined into one photo? Do I actually have three exposures for each shot and how would I see them separately? Or is my setup incorrect? Thanks very much for any input!

Thanks very much for any input!You need to take 3 shots manually which will result in 3 photos with different exposure compensation. Not sure on the icon in the thumbnails.

I was expecting to get three separate photos per shot.Actually you need to push the shutter release three separate times to create the three bracketed exposures. The first press gives you the 0 EV shot, the second creates a -2 EV shot and the third press creates your +2 EV shot. If you only press the shutter buttton once, you only made the 0EV shot. You can't get three separate exposures from just one shot because the camera has to change the shutter speed to get the various exposures.However, when I downloaded the photos with ZoomBrowser there was only a single photo (actually two because I shoot in RAW/jpeg). The thumbnails in ZoomBrowser show however a tiny icon in the corner showing three layers - which I've never noticed before. So it seems like the three exposures for each photo have been joined into one photo?No, this icon just seems to indicte that the photo is one of a bracketed series.Do I actually have three exposures for each shot and how would I see them separately?You only have one exposure for each photo. You could have multiple photos with different exposures. If you didn't cancel the AEB after taking the first photo, the next photo you take of whatever else will expose at -2EV, and will likely be darker than you expected. The next photo after that will have the +2EV applied. Look at your shots to see if that is the case (check the exif data)Or is my setup incorrect? Thanks very much for any input!

Because the camera needs to change various parameters to change the exposure, you will need to take three separate shots per series. Canon let you control this as three separate mages rather than one burst to allow you to keep framing and so on rather than having a significant viewfinder blackout as it rattles through three images at once. -- http://www.flickr.com/photos/narcosynthesis http://www.illaname.deviantart.com

It is also possible to use the timer, which will then take all 3 shots.

Did you hear the shutter release three times? In continuous mode you have to hold the shutter release button until all three pictures are taken. If you release the button in the middle of the sequence you interrupt the process. The next picture you take will continue the sequence. This caught me by surprise a few time when I forgot to reset the mode.From research I've found (I don't use Zoombrowser), it looks like the icon appears whether or not you complete the cycle.The best way to tell if you captured everything correctly is to view the pictures on the camera in playback mode. You should see all three pictures there.

Thanks all! Your answers were clear and make perfect sense. Very much appreciated!
