PeterN wrote: It also seems to be that a glass filter will greatly extend the exposure time, making IR useless for anything but landscapes. True if the camera has an IR blocking filter. But if yours is converted, you should easily be able to hand-hold the camera. I can get 1/125 @ ISO 100. The sensor will see plenty of light come through- just not visible light. So if you try to look through a Hoya R72 you will not see anything but the camera will "see" a lot. m-m Photo Gallery: http://www.mhmyers.com |

I don't think I could hand hold a camera with either of those. -- Peter |
