Cameras and Lenses
I have a question for the more knowledgeable:<p>Color filters on the sensor split the light into three wavelength ranges - red, green, blue. Then photosites measure intensity of light, which means that sensor only knows that the incoming photon is "roughly green", but doesn't actually recognize its precise wavelength.<p>So e.g. when the light is pure orange, it falls down into red wavelength range and is counted as red.<p>Based on this I would expect that cameras would often produce pretty incorrect colors, but they are usually pretty good (after correcting for stuff like white balance).
