HDR in the Stanley Hotel
HDR is a two sided coin. On one side, our eyes handle dynamic range so much better than even modern DSLRs do. HDR can help us compress the dynamic range in a scene to make it possible to compress it just enough to capture it with our equipment. On the other side of the coin, some folks use it as a tool to create images that would never be seen in nature. Myself I tend prefer the first side of the coin. If you want to learn about making natural looking HDR images, Jason Odell offers some great classes on that.
This weekend when I was at the Stanley Hotel, I was shooting some images of the stairwell from the main floor, and found that even though I was using my D800, I needed just a little bit more dynamic range and turned to HDR Efex Pro 2.
