Here is an image of what happens when I turn the camera off and let it get back to ambient and then turn it back on to -15C. Just a bit of frosting and look at the size of that dust mote. Compare with the second one that had been brought down slowly and allowed to slowly sublimate over about 1/2 to 3/4 of an hour
