Zooming

This can be a pretty effective way to abstractify an image - although it is a well-used technique. As with other techniques that involve movement (of the camera) it tends to come with a penalty of reducing the contrast considerably. So be prepared to enhance contrast and/or colors in post-processing. I captured the following shot by looking into an abandoned building through its glass front. Using a tripod an ND filter, f22 and a 4 second exposure I managed to produce a relatively smooth and even zoom from 24mm to 70mm - or was this the other way around? I honestly don't know. But I suspect that the results in this setup would not have been much different. Using the tripod was essential in creating straight lines when zooming. If you move the camera while zooming (which will be inevitable when hand-held) the results look pretty wild. This is what I got - after turning the results to black&white + some contrast-enhancing. I also produced a "negative" by inverting the curve which interestingly now makes the image as if I'm looking (from the darker) inside out. It has something of a ghostlike appearance.
