OK I'm a believer in "Not_0" now (even without spending hours researching).

One other consideration (not a suggestion, just a thought) might be to allow a
margin of error since a value of 1/256 seems to indicate that the intended
result is a value of 0 barring any of the conditions you mentioned. So if the
lighting is even the slightest bit too bright then an unintentional "1" could
result. So perhaps a default value with a little "wiggle room" might be
appropriate, like 1/265 since it's an arbitrary starting point anyway.

Kind regards,
