Nikon D200 - HDR processing removes camera data.
Here is an attempt using two separate methods to obtain a nicely exposed (hopefully composed) image. First I set out to take a few HDR
shots. I will explain HDR
in a minute. Secondly, I invoked the Zone System
created by Ansel Adams back in the 30's.
HDR stands for High Dynamic Range and is used quite extensively by many photographers both experienced and entry level. One of the big problems with cameras (especially digital cameras) is lack of range from black to white. Us humans see far greater levels of black to white than a camera can. Therefore our cameras usually have to loose the bright sky or the dark shadows in a contrasty image. HDR allows us to cover most of the range from black to white in post processing (on the computer).
The Zone System is simply a method to help us photographers compensate for what a camera "thinks" should be a proper setting. We know brightly lit grass should be brighter than what the camera determines, so we adjust accordingly. This is a simple explanation of course.
