I tried today to generate the icm profile for my D7200.
First ViewNX 2 is not compatible with D7200, so I had to use Capture
NX-D, however the process is otherwise identical.
Generating the jpeg for one single nef file, I got as a result 5 icm
files:
- 4 starting with Nkx_D7200_xxx
- 1 starting with the name Nkx_LinearYcc.icm
After remove the duplicates, I ended up with 4 different icm profiles.
- 3 have the colorspace YCbCr and could not be used by darktable
("unsupported input profile has been replaced by linear Rec709 RGB!").
- 1 has the colorspace RGB and could be used by darktable but I got
completely incorrect color (like it was the negative of the picture,
like in old times).
Usuing gcm-view I have exactly the same result as Colin (error on the
one with colorspace RGB).
So it seems that I can not use this method to generate an input profile
for my D7200 ?
Or have I done something wrong ?
Thanks
