Dark Current Non-Uniformity (DCNU)
1

I have been investigating Dark Current Non-Uniformity (DCNU) for an upcoming article (or articles).
I have a detailed analysis on one camera model and a less detailed analysis on a couple of others.

I suspect that the effect of DCNU varies considerably depending on sensor technology (and perhaps to some extent on firmware).

I have made an appeal on the Astrophotography forum for a 30 second lens cap shot at base ISO, for as many camera models as possible as part of my study. (Your contributions are welcome of course.)

Without disclosing my incomplete analysis, how do you imagine that DCNU might be characterized?
