Good day Lee,

there are several aspects of your question

1.
Be aware of the fact that 14bit images will usually be opened and
handled as 16bit images.

2.
If you deal with color images, be aware of the fact that ImageJ doesn't
handle 16bit RGB images but represents them as stacks with three slices
that are R, G, and B respectively.

3.
Be aware of the fact that quite often you need to use the B&C dialog to
make 16bit images or stacks look as desired.

4.
I was able to open a .NEF image using "BIO-Formats Importer" with setting
        View stack with: "Standard ImageJ"
        Stack order: Default

5.
If you have successfully opened the image as RGB-stack go to "Color >
Channels Tool..."

HTH
