display Nikon z7 ii nef files on iPad Pro
I can view Nikon nef (raw) files on my 2020 iPad Pro running 15.7 if they are small (4128x2752 pixels) or medium (6192x4128 pixels), but not full-size (8256x5504 pixels). Images were shot using my Z7 ii in 12-bit lossless compressed in all cases. Images from a Z9 (same sensor, color depth and compression) also have this problem. Each image flashes briefly 6 times, and then goes to the standard "nef file" generic image. How do I fix this problem? The Z7 ii has been out for 2 years, but my search in the forum didn't turn up anything on this.
