I’ve used pixel shift a few times now - always on a tripod with a motionless subject. Then I set up a user mode for it, and last night when taking a quick snap of my daughter I neglected to check my mode dial - and was still in pixel shift. The top image in this diptych is the photo as Lightroom (Mobile) saw and processed it (When I get home I’m going to see if it’s any different on desktop). The bottom pic is jpg developed in camera - and then tweaked a little for exposure and such in LR Mobile, as my pixel shift user mode is manual exposure, and I didn’t check that either (forget my head, next...).
So, I guess LR (Mobile) doesn’t know what to do with any movement during pixel-shifted exposures
(I’m simply assuming that the jpg the camera gave me does include the pixel-shift data, not just a standard pic).
I found it quite amusing, anyway 8)
