Always looking for new sources of light, my ears perked up when I noticed that Bjorn mentioned flash as a source of IR light. So of course I grabbed my D70, an 87c and gave it a quick try. 50mm @ f1.4, 1/60, random WB, SB800 at 1/2 power. Didn't really try to focus. I'd say it does a great job. Thanks Bjorn! Am going to convert this camera to IR only when I get a chance so I might be able to focus. Now I just need a source of UV... I did have a UV curing lamp at one time.
