I have used RSE, PS Elements 3.0 and ACDSee 7 and have found that when processing RAW NEF files I get a different exsposure result with each one. Then I bought Nikon Capture and found that it processes NEF files consistently and gives me the exposure that I expect with the shooting parameters that I have used. I still like to finish up in PS Elements before printing Mainly because I have not yet taken the trouble to learn Capture thoroughly.
That seems to be about the standard flow. Check and correct camera settings in Nikon Capture (or RAW processor of choice) and finish up in PS or Elements.
D7000, D70, CP990, CP900, FE + a lens or 6.
Ha! See, I can change...
