I say "Real" because I believe many of the IR shots on this site are faked in one way or another.
I think people use photoshop a bit too much. Photoshop is only needed to change the original image (which is a pinkish red colour) into the blue/white image you see.
I personally believe that many people do more than just changing the colours such as cloning/copying/pasting. But they don't admit it. I have seen some images which have an impossible reflection. The reflection was something you could only get if you copied the image and flipped it over and edited it well.
EDIT: This is now a croped HDR version
