Does Zorki5 seem to know how matrix metering is actually implemented for those cameras?
If you are asking about any level of certainty, then I'm afraid even Canon engineers responsible for similar systems in
their cameras may not give you an answer that would satisfy you.
BTW, it's OK to ask any questions, but I'd appreciate it if next time you do it directly.
He is just speculating wildly. That is all he is doing.
That is 50% correct. I am indeed speculating/guessing, but I wouldn't say I'm doing it wildly. I am giving you an educated guess.
I have a US patent in image processing, I designed and implemented entire graphical subsystem for proprietary operating system (sold in early 2000th in the US as PDA FW), designed and implemented graphics formats, compression algorithms, libraries, you name it. Took Grand Prix of an international programming contest in 1993. Chances are you, Isaac, are using map or navigation software, graphics subsystem of which one of my teams helped to develop. Believe me, I can go on and on.
I find the subject of this thread very interesting, if not fascinating, and don't mind diving into tech details a bit. If this sounds like gibberish or out of place here, I apologize, but can't help. And I'd say that, with all my speculations, I am on topic in this thread, and you with your remarks are not.
If you think it's a waste of time, again, I can't blame you, but please note that this is exactly how I feel when someone spends more than 5 minutes on the topic of subtleties of color management.
We could blether on about simulated annealing and genetic algorithms and fuzzy logic to as little effect.
You know what, that's an interesting proposition...
