AEB Help

[Pete Gl]

I have a Canon 50D and, whilst I have used AEB before, I've never really thought about it.

If I want a narrow depth of field I could use my 50 1.4 lens. If I set the camera to manual, set my aperture to f2 and note the correct shutter speed for the situation.

If that speed is, say 1/100, I set the camera to TV mode and set the time to 1/100 and an AEB value of +/- 2/3 stop.

Will the camera vary the aperture size, thus varying the depth of field, or does it possibly vary the ISO value, thus not vary the depth of field?

Thanks for any help

It will adjust the apperture in TV mode

As far as I am aware the camera will never switch ISO:
Av shutter speed changes
Tv apperture changes
M also changes shutter speed (at least it just did on my 350D when I tested it)

Thanks for your help guys.

The 50D has an auto ISO option but I don't know what happens to it with AEB
