Digital UV IR Forensic Photography – Ultraviolet & Infrared

Make the switch from film to digital and shoot all of your UV IR forensic images digitally.


Full Spectrum Conversion For UV IR Forensic Photography

Our full spectrum conversion service is perfect for forensic photography applications. Instead of having to deal with a film camera and the associated infrared and ultraviolet sensitive films you can move up to a fully digital system. Changing film in total darkness or in a changing bag would be a thing of the past. Not to mention the constant guessing of exposure and focus, having to take dozens of shots just to make sure your exposure and focus bracketing would at least increase the likelihood of a good shot. With a UV IR digital system you no longer have to do any of that. Since there is no film, all the images are recorded via the cmos or ccd sensor onto a memory card were you can instantly and right on the scene view your results and make adjustments as needed. Also, many of today’s digital cameras are capable of the live view feature, meaning that you can see the shot you are about to take before you take the shot on the screen on the back of the digital camera. This way you can adjust your infrared or ultraviolet filters, UV IR light source, composition, exposure, focus and all while seeing the image in real time.

Be sure to visit our Forensic photography gallery as well as the UV photography gallery for some sample images.

Stock Digital Cameras vs Modified Digital Cameras For UVIR Forensic Photography

Normal digital cameras are made to photograph visible light, as we humans see it. If the camera was to capture anything else along with the visible spectrum it would look odd and unnatural. Since digital camera CMOS and CCD sensors are also sensitive to ultraviolet light and even more so to infrared light, Canon, Nikon, Fuji, etc all filter out both the UV and IR portions of the light spectrum, basically blocking it form ever reaching the sensor. So if you were to place a UV or IR filter and take some photos you would find that the image is very dim or non-existent, requiring you to boost your ISO and/or exposure significantly, in most cases on the order of 10+ stops for IR and UV may not be detectable at all. What we do is remove the internal filter assembly that blocks UV and IR light spectra and in it’s place install a clear filter that is transparent from 280nm all the way passed 2000nm, well bellow and above what most digital camera sensors are capable of “seeing”. This modification opens up the full sensitivity of the sensor from UV through IR.
