人眼动态范围大,光弱几档一样看得清。等效的ISO不是个定值。
the equivalent daylight ISO for the human eye is even thought to be as low
as 1. However, under low-light conditions, our eyes become much more
sensitive (presuming that we let them adjust for 30+ minutes).
Astrophotographers often estimate this as being near ISO 500-1000.

: 在同样的环境里,我女儿的瞳孔比我大很多,这是不是意味着我的感光度高?
: 还有其他因素决定瞳孔大小吗?

我觉得我眼睛的动态范围可能有点问题,开车一旦对面太阳直射的时候很啥也看不清
