    Does pixel-shift increase resolution?

    So far I’ve only used it in the studio.  Imaging Edge worked well for me.  There is at least one other software choice for merging pixel-shift images:  https://www.fastrawviewer.com/PixelShift2DNG, but I haven’t yet tried it.

    Thanks, Ron – I’ll have to give pixel-shift a second shot.  I do like to see every pine needle on every tree on that mountainside a half-mile away.  🙂

    I tried 4-way with my A7Riii on a mountain landscape circa fall 2018.  It was early morning with very still air, and I weighted down my tripod for extra stability.  I could see a difference with extreme pixel-peeping.  I used Sony’s Imaging Edge software, which I was not impressed with.  At the time there was at least one video online demonstrating bugs in Imaging Edge pixel-shift merge.  Is it any better today?  Are there software alternatives?

    Yes. https://www.fastrawviewer.com/PixelShift2DNG

    IE is now a bit better than it was.

    I just bought the Panasonic S1R FF mirrorless camera. It does an 8 shot in camera pixel shift outputting a 187 megapixel raw image. I don’t think there is a camera today that matches it. Great detailed file at 55″ on the long side out of the camera. It has the usual restrictions of movement.

    This camera seems to be under the radar but it is a fine pro level machine.

    As a scientist, I find all this theoretical debate very interesting. However, on September 24, 2019 I posted a real-world test on the PhotoPXL website (Reply #8245). It was admittedly done under ideal conditions, but it showed a definite improvement in resolution for the 16-frame pixel-shift image over the 4-frame version. I will gladly be taking advantage of this capability whenever conditions seem appropriate.

    How does this compare to layering when using a Foveon Sensor camera like the DP Merrills?  The oddball in the Photo world that seems to perform minor miracles for some images – whether you buy into 15 or 45 MegaPixels or not.

    Leica SL2 now supports pixel shift to 187 MP as well. Comparisons on LUF claim that it does a bit better job of creating the 187 MP than S1R. Both SL2 and S1R have motion blur removal. On SL2, it works quite well for slight branch movements, though it reduces the resolution a bit.
