Default Infrared photography

"DaveC" wrote in message

I want to photograph and video in infrared mode.

I understand that some point-and-shoot cameras provide this style of
photography/videography. Alternately, some people have "hacked" a camera
by
removing the IR filter from in front of the imaging element. There are
instructions on-line to DIY this, or to send in your P&S to have it done.

Basically, the IR filter is removed and replaced with another (not a
procedure for the faint at heart). The replacement filter is $$$.

My question is this: is this replacement filter that passes rather than
blocks IR available as a gelatin or other commonly available filter that I
can source elsewhere other than from these camera-mod services?

Or can I just strip off the existing filter and not replace it with
anything?
I'm looking for quantitative data (the existence of IR) not qualitative
data
(a pretty picture). What function does the replacement filter provide
(other
than passing IR data)?

To clarify, I want to "see" IR images real-time in the viewfinder, not
post-process the image data to reveal the IR.

If there's another forum you suggest I should ask this question in, please
let me know.

Thanks,


The problem is that you won't see an IR picture per se, as the image
requires post processing to be anything but a dark red image. If your
camera has a B&W mode, that would be helpful, but the image will still
require post processing.
