And where is my earlier post?
The one where you made a derogatory remark directed at me? No doubt it was deleted by a mod.
No it is about words, and what we mean.
HTP is nothing else than while the camera metering for 200iso the gain is smaller (around 100iso gain) and thereby we get a head room. ( I describe this as an under exposure) because the camera is metering after 200iso)
You get the same effect by under exposing 100iso 1 stop and later correct the raw file in the raw converter
In Jpg the camera lay a smoother contrast curve which make a smoother high light reproduction and also lift little bit in lower levels which make the noise little bit more visible.
I hope I have make this message readable so every one can understand
Yes, that's essentially (or maybe exactly) what you've posted previously, and it's clear that you understand the consequences
of enabling HTP.
But it is
about words, and many times you used words describing a 'halving of light', 'shorter exposure', and 'the sensor collects less photons' as part of the HTP process, all of which are false. When that was brought to your attention, you simply restated the same incorrect information. So while you certainly understand the results of HTP, it's not at all clear that you understand the underlying mechanism, which has nothing to do with altering the amount of light hitting the sensor. Looking at the responses above, it's evident that I'm not the only one who is aware that you made incorrect statements about the underlying mechanism by which HTP works (i.e., it does not change exposure per se, but only the gain applied).
Regardless, it's clear that you have not acknowledged that you provided wrong information about that mechanism, and I suspect you're unlikely to do so. That's rather ironic, given that you earlier accused others of being unable to admit their mistakes. But as I previously stated, I'm not at all surprised by that...
