Hi all,

Got my pip guide to my 400D over the weekend. Great book lots to learn like AEB. (Autoexposure bracketing)
After reading a few posts on the net I have started to shoot most of my pics in raw format.
Should I use AEB as I shoot in raw and can change things in Elements.
Or is it advisable to use AEB at all.
I notice my card starts to fill up a lot quicker in AEB as three shots are taken of my subject.

Thanks for reading.
 
Hmmm. Why do you think you want to use AEB?

If you're shooting RAW, it's true that you can adjust the exposure in Elements - but only up to a point. If you've seriously blown the highlights, you may not be able to recover them. And if you're under-exposed, you risk introducing a lot of noise when you increase the exposure. So you can use the PC to tweak the exposure, but you ave to be in the right ball-park to begin with.

OK, how do you ensure you're in the right ball-park? I suppose one method is to use AEB to take 3 shots of every scene, say at -2/0/+2 stops, then look at all 3, see which one is closest, and throw the other 2 away. That would generally work. But it's not very efficient and I would suggest it would be far better to try to learn how to get the exposure right yourself. Learn about spot metering, exposure compensation, the Sunny-16 rule, stuff like that. Learn how to see a scene the way your camera's meter does, so that you know when it will get it right and when it will get it wrong. That's not a trivial task, but I would suggest it's the difference between photographers and people who just own cameras.

To my mind, the single biggest use for AEB is when you have a scene with a huge degree of contrast in it, so that there is no single right exposure. What you can do with AEB is take a series of exposures, each one correct for part of the scene, and then overlay them in Photoshop to create an image that is correctly exposed for the whole scene.
 
Stewart has pretty much nailed it.

Shoot raw and do your best to make sure that the picture is not under/over exposed.

HDR is another area where bracketing gets used.
 
Thanks StewartR.
I think your right I need to learn to expose my shots correctly in the first place. Don't know what the Sunny -16 rule is? I will google it.

Thanks oldgit I can see how it could be used in HDR I might have a play.
 
sunny-16, isnt that the old rubbish they used to print on the side of film cartons
bright sunny conditions use f/16 aperture and shutter speed as close to film speed as possible.
e.g. f/16 * 1/125 for ISO100 (or ASA100 as i think we called it back then)

So? Memory is cheap. Don't skimp on it.

However, with 3 times as many files to process and generally schlepp around, you might run into the limits of your computer.
