Using High Dynamic Range; similar photos but with different levels of HDR, some are more realistic and some more abstract. Its really amazing the amount of detail you pick up using this method.
High Dynamic Range allows for 3 photos to be composed together as one, with the best values of each, so it has detail in the shadows as well as the highlights. Modern Digital SLR’s allow for you to take continuous shots, and using AEB, the camera will take one regular , one under-exposed, and one over-exposed shots. Using special software you can compose these together with amazing results.
I can post a tutorial, just ask.
