I've used this file to work out how to upload files. There is a marginally interesting tale to tell. This is a 'Photomatix' picture, a blend of three exposures. One overexposed, one underexposed and one under normal settings. I used a demo of the above program to mix the three together (hence the watermarking). If done properly you can get the sky, background and foregound all in focus and minimize the effects of a bright sun and shadows being too deep.
