Kibo informs me that Timo Autiokari stated
that: wrote: Timo Autiokari wrote: Exposure adjustment in fact is a linear operation, multiplication by a factor, Incorrect. It's scaled in F-stops, which are exponential, not linear. Exposure adjustment by +1 fstop is the same as multiplication of the data values by 2. Exposure adjustment by +2 fstop is the same as multiplication of the data values by 4. So a linear operation. Just the gradation of the aperture and the time dial is logarithmic, they both affect to the data linearly. You failed maths at school, didn't you? You'll find the mathematical details in any good textbook onphotography. Then study them. I have. You clearly havn't. I won't waste my time trying to educate you, as you clearly prefer to be ignorant. -- W . | ,. w , "Some people are alive only because \|/ \|/ it is illegal to kill them."

Kibo informs me that Chris Cox stated that:
In article , Mike Russell wrote: Chris Cox wrote: Please do not feed the troll. In article , Timo Autiokari wrote nothing useful: I respectfully disagree. Timo's contributions to the group are certainly of value. You mean his misinformation campaign? Get real. I have no idea whether he has any skill as a photographer, but the comments I've seen him make on theoretical concepts are totally clueless. He's not quite as deluded as The Preddiot, but he's in the same weight-class. -- W . | ,. w , "Some people are alive only because \|/ \|/ it is illegal to kill them."

"Linear" is being used in two different senses here. The f-stops are not on
a linear scale, but changing the f-stop is a linear operation (multiplication). |
