It is possible to change during pp, but as NX has pull-down menus for camera settings starting with 'unchanged', then a star by what it is unchanged from, I find it a tad simpler to know whether one is changing or not in the case of other 'camera settings', or in the case of colour space, that I need never look at it again.....and that the 'soft proof' check also has all parameters in sync with the printer and paper, cos if anything can go wrong with printing it will and waste a nice piece of classic pearl paper, shame.

Just need to re-arrange my NEF folders with new sequence in new folder so pics are where I think they are!
