HDR, what is a HDR photo? HDR stands for High Dynamic Range. It is achieved by taking the same photo 3 or more times with varying exposure settings. They can be done by hand, or automatically. Combining the series of photos in software and then applying tone mapping techniques. I read in some magazine the HDR photos, get close to the way our eyes see the particular scene. This is great for sunsets, as it brings out all the clouds, and the surroundings out.
Went to my favorite sunset spot last night to try these out, and I must say I was pretty impressed with the way these turned out. But then again, I'm a bit biased :) Yes I did turn up the saturation a bit, but I just like the sunsets to have rich bright colors. That's just me.
