In photography, HDR stands for High Dynamic Range. It is a technique used in imaging and photography to reproduce a greater dynamic range of luminosity than is possible with standard digital imaging or photographic techniques. The aim is to present the human eye with a similar range of luminance as that which, through the visual system, is familiar in everyday life. The previous sentence was lifted directly from Wikipedia because I don't really understand what HDR is. All I know is that when you use it you can create some rather eye-catching pictures that appear to re-interpret reality.
Above you can see a photograph that I took near Stanage Edge last Thursday. What I saw that afternoon is what you get in that picture - untouched and unaltered - just the gate, the rough pasture and beyond that part of the rugged escarpment that is Stanage Edge.
Back home, I put that same picture into Lenovo "Photomaster" on this laptop. Then I looked at a range of possible "effects" and selected the following two HDR preferences to show you how a relatively ordinary photograph can suddenly become rather eye-catching and other worldly. Of course you wouldn't want to apply this visual chicanery every time you present a picture to other people for very often what we want to see is untainted reality - the truth and too much messing about with pictures can prove quite tiresome.
