Almost completely new ground for me also, unfortunately, although
my sister, who is a professional photographer (no digital yet) does
a lot of it. I have always loved the results, but the equipment
and process and paper to do infrared traditionally seemed a pain in
the butt. I have only taken about 20 infrared with the D7, some
were manual focus and some were auto. As I remember it, the EVF
did give a pretty accurate resemblance, e.g. you can point it
somewhere and see that because of the makeup of the scene there
would be little infrared affect. The great thing is that all you
need to experiment is a $32 filter..that's it
Hope this helps a bit....
