waiting for answer. Would be great if you can take a sec and
answer them
Digital Camera Mods UltraViolet or Full Spectrum?I was just wondering. I know by removing the IR Filter from most any digital Camera it will allow the camera to pick up on IR light. What i was wondering though is it possible to modify a Camera to pick up UltraViolet. or even the Full spectrum of light?

the chemicals in film are most sensitive to light in certain wavelengths to cause the photo reaction. Kodachrome was notorious for being overly sensitive to UV, so the use of UV filters became commonplace with professional photographers. the operation of CCDs is over the entire light spectrum, including UV and IR bands. Certain glass used in lens making may attenuate UV and IR, you would have to determine that with the manufacturer. similarly the stripe filters used in single chip CCD sensors, or the prism filter used in 3 CCD sensors may reduce IR and UV response as well. you could determine the sensitivity of a particular camera by pointing it at a black light.
in the way back days, i used to shoot IR film, and a typical lens does not focus IR light at the same focal distance as white light. Lenses used to have a correction line for adjusting to the IR focus point. we didn't have AF lenses then either so that may be an issue with broadspectrum imaging. That may be one of the reasons Sony Night-Shot switches to monochrome in the NS position instead of false color.

But the short version is yes, it is possible. I have a D70s that has been doctored by Lifepixel, it is sensitive to both UV and IR spectrums. That's all that camera is used for, as it needs filters to work as a "regular" camera that I don't feel the need to buy. I have other cameras for other needs.
