Hi Lello,
'Registration' a puzzler indeed
. Attatched is a link to a pdf file about intalling them on D300 and there is no mention of 'registering' them, so maybe register means install in 'Picture Controls' in the camera. Images from the D300 using one of those modes would be tagged with that particular colour mode and so should be recognised as such by NX1.3 or NX2.

I have not bothered with this on Stevies D300. She only shoots in RAW and I process in NX2, so it is easy to change the colour mode there in ' Camera Settings '.
Of the pics she has taken so far its about a 70/30 split between using D2x colour mode 3, and D300 standard.
