Please don't presume to speak for those of us who apply inverse gamma to make the best use of the available bits produced by the linear capture device.

I have followed this thread for some time. Unfortunately, it is based on some fundamental misconceptions. It is now turning ugly.

This whole diversion into audio dB is off base. Bell Labs introduced the term (decibel) dB. The �dec� part is decimal (log base 10). The bel part is based on Alexander who? This has nothing to do with physics or the human audio response. The logarithmic scale was proposed to address the problem of a large range of values. Like the difference between the sound of a mosquito flying 100 yards away and the sound of a jack hammer two feet away. The term dB relates to power (watts) but the term dBA relates to the human (audio) response. These are different. Look it up. Neither accurately accounts for differences in frequency (wavelength). None of this has to do with the properties of light (in a vacuum), or the physics of sound (in air at sea level), or the voltage of sensors, display devices, and such, or the physical properties of light (photons), or the sensitivity of vision.

There are two fundamental properties that do matter. The physics of light and exposure (basically log base 2) and the visible response (basically CIE). Digitally or chemically (film) the response to light is similar. Light and vision have different but inter-related properties.

It is obvious that none of the warring parties has read my articles referenced earlier in this thread. Specifically, the one about �Tones and Zones�. If you had, I would have seen different responses.

Everything being discussed is linear with respect to something else. Everything being discussed here is logarithmic with respect to something else. The terms linear, logarithmic, gamma, and correction are being used interchangeably without context. Thus, religion has become a factor.

BTW, binary encoding in computers does not change any of the physics involved and binary encoding has nothing to do with tonal compression or gamma.

To paraphrase an old saying, whatever else mathematics (the original term was statistics) can do, they provide a most welcome illusion of certainty.

I�m outta here.
