2 or more photos are required, the more photos at different exposures, the
more range is captured. Each photo only capture a certain range of values,
or details. So your EV+2 will get shadow details and your EV-2 will get
details in the bright areas, like clouds. Your EV+0 will get the best
details in your middle values. So the software helps you mix the 3 (or
more) photos together to have the most range possible--High Dynamic Range.
In the olden days you could take two photos of a landscape, one over
exposed for the clouds and a normal exposure for the land. You'd cut the
photo in half and paste the clouds onto the land-- old school HDR!

I was wondering: To do an HDR picture you need three or more photos at
different exposures. Well, I got a Nikon and it has something called D
Lighting which is (as far as I can tell) where the Nikon takes an image and
gives the image you take + and - 1 EV and then gives you an HDR image. I
don not like NOT having control of my image when it is creating the HDR
image. Anyone know of a program that will take an image and give it a plus
and minus value you want and spit the images out so that he can play with
it in LuminanceHDR?.... !!!! I got it..... LuminanceHDR will do it. Make
three copies and adjust the EV setting in the HDR Creation window. Not
quite as quick as I was looking for but it will work.
I've been wondering: How is using more than three different exposures
beneficial? Should you have an odd number of exposures with EV 0 being the
one in the middle?
