I have no idea what that means, but it can make for some interesting photographs. I've been experimenting, but it's still hit and miss, with a lot more misses than hits. The eggs are HDR and the tomato is not. To make an HDR photo you take two - or more - versions of the same shot which have different exposures, and then the photo editing software takes the best exposure for each particular section and combines it into one image where everything is perfectly lit. Of course, since real life is seldom perfectly lit, HDR shots often look artificial, but they can be beautiful as well. These photos were bad examples to use now that I think about it, because they were taken under very different lighting conditions so it's hard to compare one to the other. The tomato shot actually looks more artificial than the egg shot, but that's because of the flat lighting, not the HDR or lack of HDR.
