On returning to a NEF file previously edited in NX, I found it came out looking like the attached; turning off all the ticked steps did turn off their general effect,so pleased i hadn't permanently removed the eartag but did not return to original file.

View NX displays the file normally right up to 100% and prints it hair perfect. However, the quick adjustments are greyed out and importing it in to utility returns 'no valid file found'. Thus there does not seem to be any way of extracting a jpg of the full sized edited file.

PSE4 won't open it all. GraphicConverter opens a similarly corrupted file.

In this case my original edit is possibly all I want, but its bad news for the integrity of NEF files. I really do not want to have to duplicate the lot on import and then do 2 weeds - is that what is recommended as a failsafe?

Am asking Nikon technical too, but won't be on edge of seat for reply which will no doubt blame the computer. OK I think it did happen once before out of about 2000 nefs.

PS away for about 10 days from early Saturday, so not being unappreciative not responding to any observations after tomorrow.
