The 'standard' green photograph (1) seems to contain more details than the White balance corrected one (2) (pre defined based on photo)

Both transferred to black-white in Photoshop based on the green white balance (3) and the adapted White Balance (4)

What about updating the firmware for the camera?

Sorry to say, there could be the hardware problem like significant loss of gain on the red channel for some unknown reason....

I think it's not a hardware problem.  The camera functions, apart from the green filter, perfectly.

I think some-one opened the camera and inserted a green filter in front of the sensor.  Probably to use the D1x for Black-and-white photography. a l

In camera it's possible to change the fileoutput to Tiff and change the B&W processing in which case you get a large file of 16mb and B&W only.  But in camera you see the B&W effect.

Other option is to do the B&W processing in Photoshop and keep the color raw. (NEF)

Couldn’t you see the green filter by looking at the sensor?

Thanks for the suggestion Bruno.

Had to use the AC/Adapter to open the mirror.  Compared the 'green' sensor with another 'normal' D1x.

The green outcome.

With the AF-S 300/4
First one: White balance corrected basically eliminating green and increasing some yello
Second: Auto BW in Photo-shop

Both with AF-S 300/4

Second One: In camera set to TIFF and B&W processing
