<p dir="ltr">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.</p>
<p dir="ltr">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! </p>

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. <div><br></div><div>I've been wondering: How is using more than three different exposures beneficial?
