Anon E Mouse, I doubt that any sensor manufacturer consulted 'the negative' before designing.
No, but they do design in reference to sensor response which is further changed by image processing at the time of capture. So there is no real difference between film and digital sensitometry in this regards.
BTW, at the start of this forum, you used to be able to post anonymously, but MR quite rightly decided that contributors should not be anonymised. I would much rather discuss things with someone who is prepared to be recognised.
And how would you do that? Even if I gave a name, I would still be anonymous. I don't know if "drew" is really your name. (Do you think "Digitaldog" is a real name?) Nor does does your name tell me anything about you. So regardless of the handle you choose, you are anonymous.
Then again, I have had nasty experiences on internet forums. I have already been personally insulted on this one. I would rather keep the conversation on the point of this forum, photography, rather than on personal disclosures.
