High Dynamic Range imaging
The last few days I've been busy learning High Dynamic Range imaging, and the pictures here of buildings in downtown Ontonagon, Michigan, are two early results.
HDR is fairly simple: you take three to five photographs of a subject, all identical except for exposure time -- two f-stops under normal, then one f-stop under normal, then one f-stop at normal, then one f-stop over normal, then two f-stops over normal.
Next, you use special HDR software (I chose Photomatix) to combine all five photos into one. Presto. The result is a picture with highlights and shadow detail you couldn't get with one normal shot. You can also intensify the colors, as I have here, for a more painterly effect. (It works best with photos taken at night.)
Click on the photos for slightly larger and more detailed versions.
If all this has not made your eyes glaze over, you can find out more about HDR photography in the Wikipedia entry.
