10 minutes dark frame test.TEC ON.Enviroment temp is 30C
I stretch the image into low bit,and add some offset so that the hot pixel is easy to see. There is only a few hot pixels in this 10min exposure. If do not
strech ,there is no any hot pixel can be seen.The result is much better than the kodak chip.
