This sounds like a reasonable approach. However, while Capture NX 2 does open the D800 images, the quality of the images is is poor and you can't blow them up without immediate pixellation. Maybe I have a dud D800. I will keep trying but this seems like to many things going wrong for me on software that works fine for others so maybe it is the D800 that is the problem. That means I might have the problem of getting a replacement D800 when there are no cameras in stock.
I have a expert coming tomorrow to see what he thinks and act accordingly.
