> Hening, I am curious as to what this "super resolution stacking" is all about. Is it similar to photo stitching?
Hi Jonathan,
others have answered before I could. "Stitching" means combining 2 or more adjacent, but overlapping frames into one image, "stacking" means combining 2 or more (almost) identical frames into one image. "Almost" means, for SuperResolution, they must be different on the sub-pixel level, something I think is hard to avoid even if you wanted. Stitching can be done so to speak ad infinitum, whereas SuperResolution stacking is confined to 2 times the original pixel count. That is with PhotoAcute. I would not know of any other software that does this. SR stacking has 2 great advantages: 1- you need no additional equipment (supposing you use a tripod anyway); 2- the stacking reduces noise, the more so, the more shots you use. PhotoAcute requires a minimum of 4 frames for SR stacking, and by this number, noise is virtually gone! (May depend on how much it was to begin with, of course.) Hope this is useful.
Good light!
