HDR is the method of taking 3 or more exposures of a scene (preferably on a tripod) at different light/exposure levels. For example, -2,0,+2. This basically gives you three shots with bright levels, normal levels and dark levels. You can get the entire spectrum of detail that way.

Then you use software like Photomatix or Photoshop to blend them into an HDR photo. After that, there are post-HDR-processing you can do, like noise reduction, sharpening, color adjustments, etc.

You can Google it for more, or check out this site: http://www.stuckincustoms.com.

Thanks for stopping by!

I really like your photos. I am somewhat of an ignoramus on digital photography though. What does HDR mean and how do you get such high detail in your photos? The photo from the west end of the SL Temple is wonderful but gives me vertigo.
