Re: Infra Red and pinhole

George,

Thanks for the additional info. I have been to your
website as you suggested to me on the IR list. My
camera is almost done. It is a leonardo style 1 1/2
fl. I have not yet determined the pinhole dia. When
I get the camera done and figure it out, I will
contact you with further questions, if that is ok.
