Hello
I was not sure what section of the photography forum i was to post this so apologies.
I have just come across some free software for tethering your Nikon via your PC
It will tether your Nikon D40, 40X, 60, 80, 90, 200, 700, 3, 3X,
It is called Sofortbild and the link is
here That's the good news The Bad news is it is only for MAC 10.5 + so windows user's are out of luck im afraid, unless there is some free tethering software for that platform that i don't know about.
I am currently trying it out. Will let you know how it is.
