Processing digital images on a computer offers new possibilities that are impossible with ‘conventional’ printing from negatives and slides. One of these involves combining multiple images using special software to produce a single picture where the seams are invisible. The technique has a surprising number of uses for the railway photographer and this month’s article shows a range of examples. Some people may object to this technique as cheating or unnatural so it is worth pointing out that the human brain combines images from the two eyes into a single overall image and therefore predates the invention of the camera ! Below, one example this technique is shown. The original image containing the train was framed too tightly when the picture was taken. A picture containing empty track can be merged to create a perfect final image.
