This is a "surreal image" taken of Scaleber Force near Settle in the Yorkshire Moors. Its processed using high definition software, in this sample by Photomatix. It started life as a single exposed image with plenty of large dark and light areas so the camera exposure calculation had a lot to do. By taking two virtual copies of the original image and exposure compensating these copies to +2 and -2 this is were surreality begins. The three images were combined and the result is a large image file that the monitor and printer cannot convey to the human eye. so the clever bit is to tone map this image to balance all the exposure detail across the whole image. The result is a deeper dimensioned picture with richer colurs and detail, the downside is more picture noise on a larger print scale (A2).

For improved noise quality we can by using in camera technigue, take 3 compensated exposures at normal (0) +2 and -2 levels, the problem is movement and image alignment. So the best way forward is by using a tripod and by taking a picture were movement is cofined to a fixed plane.

eg. A person moving quickly across the frame cannot be aligned to one fixed point, were has a fixed flow of water is possible to simulate.
