Yes, we do weird things. The other day I was out testing some cameras for their infrared performance and decided to test the new Nokia I also have for review.
The low end of the camera market is, to a large extent, disappearing into the phone market. New mobile or cell phones (depending on where you are in the world) are having better cameras integrated into them. I’ve had a new Nokia 6220, a 5 Mpixel camera phone with GPS, for a little while for testing. So it was obvious to see how it would handle infrared photography.
The Nokia 6220 has a 5 Mpixel camera with a real zoom Carl Zeiss lens and flash. It obviously has neither a tripod socket or a screw thread for attaching filters. Thankfully I did not need the tripod socket and you can get around the filter thread issue. You do this by simply holding the filter as close as possible to the lens when you shoot. This works but you can get flare effects when shooting into the sun. Cut gel filters would work better.
So let us look at an image in more detail.
This is the image straight from the camera.
Here is the center of the image at 100%
Red channel
Green Channel
Blue Channel
Exposures drop from around 1/250 second to 1/9 second in full sun, but these low shutter speeds don’t seem to be an issue and approximate to what you get with these cameras indoors in a bright room when not using the flash.
So it does work and you can get surprisingly good images by doing a conversion from a single channel in Photoshop.
Hi Am looking for Cell phone which can take Thermal Imagies frome different areas.
Please provide details and prices if possible.
Thanking you.

Infrared, in this context, is not the same as thermal imaging. Thermal imaging uses special sensors and looks much deeper into the infrared. The infrared capability here is great for photography but won’t be useful for thermal tasks, such as identifying overheating components, etc.
