From personal experience, my best notion of linear is: Whatever it takes for MY image to appear correctly on THIS monitor using THIS current operating system and THIS current software assuming THIS specific gamma, viewed by THIS specific eyeball, all of which may change between bug reports. One proscribed "real" notion of linear is the proportion of photons activated vs. the possible proportion of photons activated within the given area. Of course, this still depends upon the range and sensitivity of each of the entities mentioned previously. - Phillip
