it's not physically possible, no matter how good sensors or electronics will get.

the amount of light at iso 3276800 per pixel for saturation is far too low, with the number of photons in the single digit range.

Sandman
ISO does not denote an amount of light,

nospam
i never said it did.

Sandman
It's still quoted above; "the amount of light at iso 3276800".

There is no "amount of light" at ISO 3,276,800. It's an arbitrary number that has no relation to the amount of light hitting the sensor.

nospam
read it again, this time the entire sentence rather than just one part.

Sandman
The quality of the end result of said amplification is what is being improved.

nospam
you can't get water out of stone.

at iso 3276800, there simply aren't enough photons hitting the sensor to produce a quality image, even with an ideal sensor and ideal amp.

physics, again.

Sandman
Ironic, coming from the guy that again is saying that the ISO setting determines the amount of photons hitting the sensor, which you said again above.

nospam
i didn't say that.

it's clear you're in well over your head. again.

Sandman
It's a fun quote, I'll save it:

definitely save it, so that you can ask others to explain it to you because it's clear you haven't a clue.

"at iso 3276800, there simply aren't enough photons hitting the sensor to produce a quality image, even with an ideal sensor and ideal amp."

yep. that's exactly correct.

once again, you don't understand what was written, and instead of asking for clarification, you immediately start arguing based on your misunderstanding.

nospam thinks a specific ISO setting denotes how many photons hit the sensor.

i didn't say that.

try reading the entire sentence next time.

what i said was that there aren't enough photons to produce a quality image, even with an ideal sensor/amp.
