Re: Defining Signal

Mean Signal in a specific area of the image is therefore the average of the photometric/radiometric quantity under the given image area or the average of the photoelectrons generated by a sensing element in a given channel in the same area of the image.

What do you think?

A nice definition because it actually mentions something other than just "the signal". Hopefully this - the Photographic Science and Technology - will someday use words like this, e.g. "resolution", with a word or two in front to say what exactly it is.

Minor rant, not aimed at anyone in particular, honest.
