The photo itself is sucky. I just ran outside and took a shot to see if it would work. The arc is from some kind of light refraction.

I'll be testing and posting with the 50mm 1.8 (which is supposedly more IR sensitive) once I get a step-up ring.

Another crappy photo below :) Better ones to come later I promise :).

Looks like someone has already documented the entire process...

how hard was it to get the right exposure? I haven't tried it all, but I know my buddy with his D70 has no metering with IR. Is the Canon a bit smarter by any chance?

It's completely hit and miss. Looking through that filter is like hanging out inside a really, really dark closet with a blindfold on. I doubt *any* camera can meter through this thing. Luckily I'm a patient guy.

I had to set the focus manually (stop laughing....i really did focus) then carefully thread the filter on. Then I set it to AV 5.6 (in the case of the 18-55mm kit lens) and started with 15 second exposures and worked my way up. I got the best results around 20 seconds on an overcast day.

I still have to get the step-up ring and test with the 50mm which is supposedly better with IR.

Thats weird...

My meter on my D100 works fine with the infrared filter in place.

I first tried a shot in AV mode. After a quick beep (focus) it promptly saved a completely black photo. :D I'll try again under various conditions. This is one time I'm glad I'm not experimenting with film.
