sunsetF16 - almost there, but exposure is wrong

i have the sunsetF16 script running for hours (days?) but now it continuously underexposes. l'm certain that a variable isn't getting set correctly but there are many to look at and i have a poor understanding as to how they interrelate so i'll post and see if its obvious to someone else.

i'm hoping to be able to release the lua libs and sunsetF16 after this is solved.
