Hi folks, I'm a bit late coming in on this thread but I use an IR converted Nikon D100 - done by ACS. And I use a Nikon 17-35mm f2.8 lens for almost all my IR work. Several of my shots in my gallery are from this camera. Some are B&W, some colour, some processed, others not. I find the main trick is the WB - my shots come out with a strong magenta cast in Auto WB but in Custom WB - usually set from bright green grass in strong sunlight - the pictures like this
1 &
2 have almost no processing. As a member also of Nikonians I posted this on their web site some time ago - it comes from the Advanced Camera Services (ACS) Web Site and I found them to be very helpfil when I had my camera converted. I think it is very useful for anyone trying out or taking up IR photography.
