I believe that it stands for High Dynamic Range.HDR is High Dynamic Resolution.
I believe that it stands for High Dynamic Range.
Camera sensors (and film for that matter) are limited in the range of brightnesses that they can see. In any one picture, you might have some part of the picture that is completely black and another part that is completely white. In real life, those black and white parts might have actually had more visible detail, but the camera couldn't capture them all in one photo. "Dynamic range" is the term used to describe the difference between the brightest and darkest light levels that a sensor can capture.
HDR gets around this limitation by combining pictures. If you take a picture with different shutter speeds, you'll get different exposure levels. In one picture, the areas that were completley black might now be visible at the cost of having even more areas that are completely white. In another, the areas that were completely white might now be visible at the expense of having more of the picture that is completely black. Photoshop can combine all of those pictures taken at various exposure levels so that one photo has a much wider dynamic range than the original sensor was capable of recording.
Yes. Just make sure that you are bracketing the shutter speed and not the aperture. If the aperture changes between shots, there will be differences in the out-of-focus areas of the photos that will prevent them from combining well.could I use exposure bracketing and then combine the pics
I think most HDR tools (including Photoshop's built-in script and stand-alone ones like Artisan) can do slight adjustments if the pictures are nearly the same.I should have also mentioned that these photos must be taken with a tripod. It's essential that all of the photos be identical except for shutter speed.
Aw crap, I have Photoshop Elements 4.0 loaded on my laptop and that won't do it. I have a full version of Photoshop around here somewhere... I want to try this!
Um... I'm guessing the images have to be RAW, right?

I really want to try this, but I need the HDR for Dummies version.
See? Why didn't you say so!
No, really - I kinda got that part. The images don't have to be RAW? Photoshop can combine pics for this effect? What about PS Elements? I haven't seen it there so I am guess not.
Thanks for putting up with my repeated questions about this process! (I mean that)
