Alrighty, this probably isn't going to be the question ya'll thought it was going to be....
This one's for all you tech heads out there. Digital cameras (at least some, if not most) are, as I understand it, by their very nature good at picking up infrared light. From what I've read, most digital's actually have a filter infront of the imager that blocks IR. As most of us know I'm sure, human's can't see infrared. Now here's the question; why don't digitals (or film for that matter) produce an image from IR that we as human's equally can't see? I.E., if we can't see it to begin with, how is it that a camera (or film) produces an image from this light that we can see?
As long as I have the soapbox, here's another semi-related question...would/could the same thing apply to ultraviolet light as well? Obviously, digital cameras can "see" UV...otherwise what would be the use of having a UV filter on your lens all the time (other then to protect the lens of course! LOL!). Will digital cameras turn something seen in UV into an image that we human's can see? What I'm wondering on the UV thing specifically is, could a digital camera possibly be used to "see" and record gamma ray bursts (like those emitted from a black hole)?
I look forward to everyone's comments on this!
