Long Exposure Stacker
Mac OS Photography
Long Exposure Stacker is a tool for combining 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.
The alignment algorithm has been modified to allow more movement of the camera as might happen if the camera is hand-held.
The maximum size of the brush used to paint the mask for optional alignment has been increased.
