Mixing darks from different cameras

Hi all, just wondering if anyone tried mixing darks from different cameras in DSS. It should be ok in theory but just want to know if anyone actually tried it and what results you got.
Thanks,
Bo

no not ok in theory, your camera always produces a unique image that no other produces.

Sensors collect photons in microscopic wells, called pixels. Sensors do their magic by assigning electric charges to these photons. These charges are read as analog voltages. These voltages are sampled and quantized to make them into digital values. These digital values go through much more digital processing before we get to see them.

Leakage currents are electric charges which leak into sensor wells. These excess electric charges increase the voltage at the well (pixel) and make it look brighter than it should.

Manufacturing variations will cause some pixels to have much more leakage current than others. It's these few pixels on each sensor which are called "hot."
The pixel-scale variations in your camera are unique to your camera.
