App: Long Exposure Stacker
Developer: Ralph Hill
Genres: Foto und Video, Grafik und Design

Long Exposure Stacker combines images to blur motion and to reduce noise. It can be used to simulate very long exposures to remove the appearance of waves from the surface of water or soften the motion in water falls and clouds. Long Exposure Stacker is an alternative to using dense neutral density filters, such as 6- or 10-stop ND filters, at capture time. Because the images are combined, the noise in the final image is reduced. This means that split neutral-density filters may not need to be used in the field. Instead, burning, dogging and gradient filters can be used in an image editor, without the risk of exposing noise. Long Exposure Stacker includes an alignment option that makes it possible to make a hand-held long exposure from a burst of images where each image is captured with a short exposure.

Release notes:
Reduced memory usage, particularly in the case where intermediate results are stored in a temp file instead of in memory.
