I read over in the signature forum that ISF-Auto with both sensors is pretty amazing.
If you calibrate ISF day and night, I know the settings are hardcoded.
What do you set/calibrate in ISF-Auto then as I would imagine the sensors would continuously adjust settings like Optimum mode. Simply put, using both sensors, how does ISF-Auto differ from Optimum?
note: the post above is my opinion. as such, when reading any recommendations from me, please do you research and seek out other recommendations and make up your own mind on your next course of action. i mean, most reasonable adults should know that, but it seems this should be stated anyways.
