[QUOTE="aroy, post: 582898, member: 16090"] Stacking images is an old concept. With stacking you can achieve any one of the following effects . Averaging of the image elements. That will smoothen out the water flow just as in long exposure . Noise reduction of static objects used primarily for astro photography . Removal of transient object. Here the software removes all non-static objects, for example a 20 shot of a busy road when processed can get rid of most pedestrians and automobile traffic leaving a clean shot. What you are referring to is the first option and it works perfectly. The beauty of stacking that you can omit any image that has an intrusion, say a person walking across or a bird flying. [/QUOTE]
