Is the 10D sensitive to IR? I don't know. But all an "IR filter" does is remove most of the visible light and allow red and infrared pass. If the 10D does not record IR or very little compared to the red, there will be no IR effect. Because the human eye cannot see IR, a true IR filter would look like you had left the lens cap on. And the filter factor would be huge.
I used a "UV" filter that passed only UV. I couldn't see throgh it and the filter factor was 10 stops. The film I was using (T-Max) was relatively insensitive to UV.
