could you provide command line for this one?

I try to run this command. but i cannot open the output file. it keep said incorrect format.

Code Select Expand

exiftool -b -DepthImage original.jpg  > out.jpg

I also try open in Photopea. and it works!
However,  Nokia advertise that "Nokia 9 pureview's Depth Map captures more than 1200 layers" (ref: https://en.wikipedia.org/wiki/Nokia_9_PureView#Specifications) but Photopea can output only 8-bit image with can handle only 256 step of depth.  Can Exiftool output depth map with 1200 step?

I found a few threads on reddit talking about this camera.  One thread seemed to indicate that the data you want would be in the xmp-gdepth:Data tag and would be a Base64 encoded PNG file.  That tag doesn't exist in your sample image.  Only the 256 level grey jpg seems to exist.

See this Reddit post.
