Scott 18 bits IS 18 stops. Or if you assume the least significant bit is where the noise is then 17 bits or stops or 131,072 levels. EasyHDR can handle 96 bits. My next imaging will be to use the 300mm F2.8L and collect data at f/11, f/8, f/4, f/2.8 and then double the exposure for another five times at f/2.8. This with the 12 bits of the 5DH's sensor will give me 21 bits potentially. Lets call it 20 bits and then we will have one million levels!
Did you notice that the Trap is almost resolved?
Should be an interesting experiment.
