I found an error (a prime symbol, ‘, omitted) in the code that I used to generate the images in the original post, so I have extensively revised it. My apologies. In the previous post, I reported on the effect of the selectivity of the color filter array (CFA) spectra on color accuracy in cameras… [Read More]

There is a widespread belief about Bayer color filter array (CFA) response spectra. It goes something like this: The old CCD cameras used to have great color. The reason they had such good color is the dye layers in the CFA were thick. Thick dye layers led to highly selective (narrow band) spectral responses. Modern… [Read More]
