Infrared Photography

[Nanfeishen]

Has anybody used or tried out Infrared filters ? and are they available locally ?

Has anybody converted a camera to full spectrum ? and if so, are there people who do it locally ?

Aren't you referring to near infrared by exploiting the existing camera sensors.

Unless you have a CAT S60 or a FLIR dongle , it is not true infrared and just a filter to make it look like an infrared photo?

Something along those lines , for full spectrum apparently they strip out the low pass filter and replace it with a clear filter.

Thermal and Infrared quite different.

They are actually quite close related as far I am aware ?

I think the tip is in the name FLIR

Forward looking infrared
From Wikipedia, the free encyclopedia

A Thales Damocles FLIR Targeting Pod.
Forward looking infrared (FLIR) cameras, typically used on military and civilian aircraft, use a thermographic camera that senses infrared radiation.[1]

The sensors installed in forward-looking infrared cameras—as well as those of other thermal imaging cameras—use detection of infrared radiation, typically emitted from a heat source (thermal radiation), to create an image assembled for video output.

They can be used to help pilots and drivers steer their vehicles at night and in fog, or to detect warm objects against a cooler background. The wavelength of infrared that thermal imaging cameras detect differs significantly from that of night vision, which operates in the visible light and near-infrared ranges (0.4 to 1.0 μm).

Experimented with full spectrum by opening up a webcam and removing the IR filter. This was a five minute job with the really cheap one that I used. Since most of the sensor sensitivity is in the frequencies that are normally blocked by the filter the webcam became very sensitive in low-light conditions. In daylight it tended to over-saturate and additional filtration would probably be required.

Next I assembled as array of IR diodes into a flood lamp. Due to the high sensitivity of the webcam this was able to illuminate a fair area at night with low power consumption. The inevitable conclusion was to then couple it with motion capture software to see how well it functioned as a surveillance camera.

The results were positive. If I get enough time I may modify a Pentax K100D DSLR that is lying on the shelf as a low-light camera.

...and no, I am not a creep.

:crylaugh: never thought you were

I was watching an episode of Ghosthunters ( yes i know lame) and the one guy was using a full spectrum camera, which i found rather fascinating, so with a few older camera's lying around i thought it might be nice to have something a little different in my collection and if i ever land up somewhere with odd reports, to give it a whirl for a bit fun and curiosity.

Found these guys, they seem pretty waxed on the whole IR photography field.
