A nanometer (nm) is a metric unit of length equal to one billionth of a meter. Your eyes can see a range of light from approximately 400 to 700 nanometers. Most digital cameras place a low pass filter in front of the sensor to lets low frequency light visible to the human eye pass through to the sensor where it’s captured and recorded but blocks unwanted light from the infrared and ultraviolet spectrums (the high end...
