It has been a while since my last message, mostly because I was on military service in 2006.
However, I got last week Heliopan Hot mirror filter which filters out allmost compleatly IR-band and some UV-band. I desided to try it with DCS 420 and today I was out for a little spin with DCS 420 and Nikkor 28/2.8 with Hot mirror installed.
Well, today the IR intensivity wasn't very high, but the filter seems to help a little with colors. I'll test some more when there will be more IR-light.
And here's link to the pics:
These were made with CS3 beta.
PS: Ambient temperature was -15 degrees celcius and the 420 did run for about an hour and 70 pics. Quite good performance with PC-card hard drive.
