<big>As a camera/light meter should try to reproduce the human

Perhaps what you need to do is to make some measurements (using a
smartphone or old-style lightmeter) over a period of a couple of
weeks, at night in both cloudy and non-cloudy weather conditions,
and with both full and no moon. <br>
<br>
Write that up as a diary entry, and then people will be able to
reproduce what you've done to measure illumination elsewhere?<br>
