On: Resolution of the human eye

[Synaesthesia]

I don't quite get how he estimated the ISO equivalent of the eye - he compares it to a camera taking 12 second exposures, whereas the eye is essentially video, as he says, implying 1/15th sec exposures.

[j-g-faustus → Synaesthesia]

He also says that "at low light levels, the human eye integrates [light] up to about 15 seconds".
