Subject: Re: Exposure to the right and tone placement





When we convert from gamma 1.0 to 2.2 we lose tones. According to Bruce
Lindboom's calculator, we start out with 4096 levels in a 12 bit gamma
1 capture, but end up with only 249 levels after conversion to gamma 2.2.
What is your take on this loss?




I think you might want to do the calculation again.

12 bits in and 16 bit out gives 4096
12 bits in and 15 bit out gives 4096
12 bits in and 14 bit out gives 4096
12 bits in and 13 bit out gives 4065
12 bits in and 12 bit out gives 2938
12 bits in and 8 bit out gives 249

according to the calculator
