HDR Question

[israelv]

Can I still do HDR even if my camera doesn't have Automatice Exposure Bracketing?

Yes. You can bracket manually, you know. Just adjust the shutter speed to cover the exposure range you want. 1EV = a stop, which is a doubling/halving of the light. So, if, say, you wanted to bracket so that you had three shots, at 1EV intervals, and your middle exposure had a shutter speed of 1/200s, you'd leave the other settings alone, but take one shot at 1/100, one at 1/200s, and one at 1/400s.

If you wanted to bracket at 2EV intervals, you'd use 1/50s, 1/200s, 1/800s.
If you wanted to bracket at 3EV intervals, you'd use 1/25s, 1/200s, 1/1600s.
If you wanted to bracket at 4EV intervals, you'd use 1/12s, 1/200s, 1/3200s.

If you wanted to bracket seven images at 1EV intervals, you'd use:
1/25s, 1/50s, 1/100s, 1/200s, 1/400s, 1/800s, 1/1600s

You want to use shutter speed for your bracketing instead of aperture or iso because with shutter speed, you can use a tripod to reduce motion blur. With aperture you might have different focal points and DoF, which would make sharpness and matching images for the HDR merging difficult, and different iso settings would create different noise patterns.

The biggest problem would be anything that moves between shots (people walking by, etc.). That can cause "ghosts" (transparency from a person being in one shot but not the others), or "clones" (from a person moving to a different point in each shot, and showing up multiple times, as in multiplicity shots).

Miss, what about those of us that have never used Auto bracketing and did it the manual way the first time?

You can also just use the +/- exposure comp adjustment

Yes, yes. My Canon-think gets in the way of the easy answer again. Both of my cameras only have a ±2EV EC range, which just ain't enough. Yeah, our AEB sucks compared to Nikon's.
