This process merges a UV/IR photograph with an ambient light visible photograph. However, if you want to take a photograph of someone in the dark they're going to end up looking like the bogeyman.
- chancho 17y agoIt's not supposed to be night vision. All I want out of a digital camera is the ability to take hi-res indoor photographs without flash. Consumer-level cameras have modestly-sized CCDs that can't gather enough light fast enough indoors, so the picture is either noisy (not enough light gathered) or blurry (exposure is too long). This aims to remedy the former by using the UV/IR photo to smooth out the noise.
- skalpelis 17y agoA fast lens might help (if you're into SLRs). f1.8 50mm prime is cheap, though anything faster will cost you.
- jacquesm 17y agoWhat he means with 'fast lens' is a lens with a large aperture so that more light reaches the film/sensor in a shorter time. There is nothing inherently 'faster' about the lens, it is just a figure of speech.
