comment What causes chroma noise in an image sensor
@szulat, for the most part I'd agree with that statement, but depending on the CFA position and by association the wavelength of the photon, the photon will penetrate the silicon deeper for one colour component compared to another. I disagree that the chroma noise is due to demosaic failures

comment Imbalance in green pixels
Great - one small request before I mark this as the answer; would you mind just clarifying the point of different sensitivities - is this related to the different absorption depth of red versus blue or is it something to do with additional electrical circuits (perhaps as part of the readout circuitry).

@agf1997 that seems very plausible. If you can add this as an answer, I'm happy to mark it as such. I would like to understand what causes the differences in sensitivities? Thanks

I'm happy for this question to be moved. My reasoning for posting the question here is that there seems to be very knowledge sensor folk answering questions here

Well they are in different physical locations, though I understadn your point it should be twice as fast. Speed isn't that important to me though - I'll do the transfer at night and/or over a weekend.

comment Why are some of my photos coming out almost completely purple?
As an artifact it almost looks like a dithered image with excessive saturation of a badly exposed scene. Definitely more than just a little "off"

I agree with Russel, you'll need to provide some more information about the purle image and the window scene. I assume the purple part is a 100% crop of a specific purple area on the wall looking through the window? Also could you mention what type of camera is this from? and also is the output image RAW or jpeg?
