These people install infrared filters in digital cameras. I find it a bit unclear if you can use the camera in normal mode after the filter is installed. They do show pictures of images taken 'seconds apart' but I don't see how you could add a filter in the camera and then switch back and forth sort of removing the filter.
David - Per the FAQ, what they do is remove the IR blocking filter that currently sits in front of your sensor (and replace it with their own clear, or IR passing filter). All sensors (I think) are somewhat sensitive to IR, but it's filtered out.
If you get the clear filter, it allows "full spectrum" shooting. Once the conversion is made, you could put a filter in front of the lens to filter out whatever light you don't want. I'm not sure if this is what you're referring to though.
I think the website is a bit unclear from my reading as they state that the conversion eliminates the need for an external infrared filter. I suspect if you have the change to one of their three conversions, to obtain normal shooting you need put on an external filter. That they show three results by the same camera taken at the same time, would seem to imply that there was some form of camera control for their filters.
The site was forwarded to me by someone looking for a cheaper way to do aspects of thermal imaging with their P&S office camera which they also use for documentation on other projects. As the camera doesn't accept filters it would seem such a conversion wouldn't be in their interest.
It would seem that if you had this conversion you would want a dedicated camera for infrared.
"The advantage of a clear full spectrum conversion is the ability to change filters in front of the lens. You can shoot UV, visible, IR and everything in between depending on the filter you use. So you can acheive all of the above images and more, with apropriate filters.
The disadvantage is also the fact that you have to use filters in front of the lens and since IR filters are opaque black the viewfinder will be blocked making it harder to compose, meter and focus.
This conversion is mainly used in special applications photography like forensics, astronomy, medical, etc."
So if you get that clear filter, you DO need external filters to do IR, visible, UV, etc specific photography. I'm assuming this is how they use one camera to do multiple shots quickly.
There can't possibly be any camera control over the filter they place on the sensor, as far as being able to take visible light photos with an IR-pass sensor. Once that's in place, you have an IR only camera.
