Want to create a long exposure photo but don’t have a camera that can keep its shutter open for extended periods of time? Mansour Moufid of Elite Raspberries is working on a script called “Hipshot” that can take ordinary video footage and convert it into a faked long exposure still photo. He writes,
Long-exposure photography is a technique to capture dynamic scenes, which produces a contrast between its static and moving elements. Those parts of the scene which were in motion will appear blurred, creating a nice effect.
[Above] is a long-exposure shot of a stream I took recently. It is technically not a long-exposure photograph, but a simulation; this image was actually generated from a video recording taken with an old iPod, which was then processed in software into a single image. (Forgive the poor quality, I don’t own a good camera. Nonetheless, this image demonstrates the desired effect.)
