Hi Taku, thank you for the generosity in sharing this. Question, do the Nikon Z8 or Z9 output a RAW / NEF Multiple exposure image or is it JPEG? I believe in-camera multiple exposure is available in all NIKON cameras or is it restricted to some?
The resulting multiple exposure image is JPG. As far as I know this feature is available in all Nikon Z cameras, including the latest ones like the Z 6iii, and Z f.
