When I open a NEF file in Capture NX2, it seems to drop in contrast and sharpness after a few seconds. Why and how to fix this? Pls help.

It takes a little bit of time for CNX to apply all of the adjustments in your raw file to the image it actually displays.That delay that you see is that little bit of time.

The raw file is just data that must be interpreted by CNX to a displayed image. Aside from the basic image date, the raw (NEF) file contains the instructions for the raw converter to interpret and then display the adjusted image. Depending on your file size, camera settings, adjustments that you have made in CNX and the speed of your computer, that processing time can be almost instantaneous, or take a second or two.

If it is the first time you open a NEF file in CNX, it creates a preview JPG that will be embedded in the NEF once you save it, unless you've changed this option in CNX. You'll notice a significant increase in your NEF file if you open it, then save it with no additional adjustments. This preview also takes some time to generate, and I suspect is better processed than the thumbnail JPG generated by the camera itself.

Best bet, after you open an image, or make an adjustment, let CNX "settle" for a 2 or 3 seconds before you judge the results. Then you can easily adjust contrast and sharpness in CNX.

In the upper right hand area, above the adjustments options, there is clock face type of icon which turns when processing is still on-going. It's been my experience that this can turn for several seconds when doing certain types of adjustments (like better quality 2012 noise reduction) so a quick glance at the icon can let you know if processing is still under way.

It is also possible that your camera settings are for sRGB color space and those in CNX2 are in Adobe RGB.
Just make them consistent (the same).
sRGB is best for Internet display.

Have a great time :-)
