Neither the sensor elements in a camera nor the pixels in a monitor are selective for a single wavelength, but rather a spectrum. So we don't actually approximate cone response that way. The fact that we store the channel values as three integers does not change this.
- acjohnson55 12y agoYou're right that monitor pixels aren't individual wavelengths, but the spectrum of a reproduced image can be very different than the spectrum of the natural image. My point was just that you don't want your flat lens harshly filtering that natural image by only working one 3 wavelengths.

My point was just that you don't want your flat lens harshly filtering that natural image by only operating at 3 highly tuned wavelengths -- that's not going to be enough to capture natural images, despite the fact that we can reproduce them with 3 components.
