Warning - after editing some difficult pics in both 1.3 and 2, I have decided to go back to 1.3 on grounds of final quality as well as previous doubts.

However NEFs edited in NX2 do not come through with editing done in 'Quick fix' (and maybe other new tools). Although the QF pictogram looks like the LCH>'master luminosity', it acts independently. IMO, not as well, partly as it is smaller and partly as it does not have numeric corner windows giving exact values of edge sliders. LCH is the function I use most and can't afford to lose its quality.
