language problems, aside, when all parties are interested in finding truth, success can still happen. The problem here is that truth wasn't discovered during the process. it was hammererd out with great pain. this what disapointed me about the discussion was that it did not converge. instead it went something like this:
HTP halves the number of photons hitting the sensor
no thats not true all the time
yes it is true, see my ISO100 example
ok for the special case of ISO 100 that is true, what about the other cases?
the number of photons is halved, see my ISO100 example
no that can't be true: when ISO is 200 or 400 or 160, the number of photons is not halved
yes it is true, half the photons strike the sensor, see my ISO100 example
be specific: how does HTP work with the ISO dial is set to 400. is the number of photons halved?
HTP benefits jpg shooters
you need to say that the number of photons is not halved when the ISO dial is set too 400
no I won't please see my ISO 100 example.
Don't you see that when ISO is set to 400, HTP does not halve the number of photons
I've been saying that all along.
clear, precise technical explantions are more difficult when language is a issue, but they can still happen, and I hope they do, in the future. I for one was frustrated becasue we could not get the conversation to converge on the true technical mechanism underlying HTP that would happen in the majority of the cases and for the majority of togs, i.e. those who have not glued their ISO dial to "100". suede I'm glad you finally summarized it. whew
