Does sound a bit bizarre...

I can't figure out what he is talking about, unless the camera he was using was defective in some way.

BTW, my result for electrons at raw saturation are consistent with what John Sheehy is reporting, but I think he is using similar publicly available raw files that are less than ideal for this measurement.

Certainly the result I quoted should be regarded as a lower bound, since the systematic errors tend to suppress the resulting QE measurement.
