HDR: High Dynamic Range see my sample below. Made with one exposure, then made two copies in PS. One 2 stops over and another 2 stops under. I then loaded all 3 exposures into Photomatix Pro to generate the HDR file.

In reply to Frank Bruce....I tried to follow your instructions in photoshop, but couldn't get there. I have Photoshop Elelments 9 version: went to image, and a drop-down came up with the following listed:
Rotate
Transform
Crop
Recompose
Divide Scanned Photos
Resize
Mode
Convert Color Profile
Magic Extractor
But, no "adjustments" could be found...

Single shot HDR is essentially Photoshop's image adjustment that brightens the shadows, tones down the highlights. You then add sharpening, saturation and exposure. This simulates HDR. Other functions can be performed, but these are the basics.

Susie, HDR (high dynamic range).
If you have a scene with shadowed, dark areas as well as bright sun lit or open sky areas, our digital and few film cameras can accurately capture the image. The light brightness range from the lightest to the darkest is greater than we can handle. Your eyes can, but the camera can't.
True HDR requires at least three shots. One under exposed to get the details from the lighter areas. Another over exposed to get detail from the poorly lit areas. The final is properly exposed and used as a base to apply the other two. The finished photo uses the details from the first two to fill in areas on the properly exposed image.
You end up with a photo that is filled with data and details. The contrast levels are high, and colors are accurate. Just adjusting brightness or contrast won't work.

It is short for High Dynamic Range(HDR) where you make a composite of several bracketed shots. You can achieve this by using programs such as Photomatrix Pro or several others.

Thanks, Paw Paw Bill. This explanation really helps me to understand what is happening with the whole process. I really appreciate it ! Nice to know the reason for it and how it works basically. I will use this in the future. I like the look of it so much. I have looked at the photomatix site and will try a free download soon. Do you use this one too?

I type slower than I can think (which is also getting slower since I passed 65). I left off a 'not' in my post. Digital cameras can NOT capture the full range of light in a single photo. Film can get more, but not all, unless you use special emulsions that probably are not available anymore (even they could not get it all).
I don't do much HDR, but, currently Photomatix is as good as it gets. Others may equal and I am sure that soon, they all will get better.
