Does that mean it needs to be tripod mounted? To make sure things that aren't moving stays iny focus? Can't be handheld? Otherwise you will have overlaps at the edges?
Sony's explanation of the app is so simplistic.

"....sequence of continuous shots..." am assuming it blends the moving waters to achieve smooth reflection. .
Well , need tripod? Assuming u exposing to the sky at 1/500 shutter speed then u probably can go handheld.. I haven't got the chance to apply actual use yet. . Whereas in typical big stopper application, u will definitely need tripod in order to balance out the ambient light to achieve smooth water look.. hope this helps.
