How about the Sony A7R IV pixel shift image for a 240.8 MP image? As far as pixel shifting yes like HDR shooting if something moves the shot is ruined (sorta,) HDR use deghosting functions . And with Sony you need to use Sony software and maybe the same for other makers using the makers software. Maybe one day Pixel Shift software will be plentiful like HDR software (Bracketing software) today. Ideas for the young programers of today!!!
