Once upon a time the picture you took was captured on the emulsion of a film and, apart from some minor tweaks during printing, was the one you lived with. But Digital changed all that. A digital picture is only the starting point for those with imagination.
You probably look at some pictures and say "I wish I could have taken that" to yourself. But that image may have started out as a relatively humble exposure and then been give post processing tratment to make the most of it.
Watch how Peter Eastway sets about taking a set of fine exposures of a tropical storm and really peps the image up. Lots of use made of Photoshop layers.
