I always wondered: is there anyway to distinguish an evening from a morning through the sort of light we see. So Image you see random pictures and don’t know if it’s dawn or dusk. Can you see the difference?

Interestingly enough, if you aren’t familiar with the location, there’s no foolproof method to tell whether it’s morning or evening by light alone. There may be cues, like if it’s a city then the properties of light could reflect the denser pollution it has to penetrate in the evening, but that still depends on location and time of year.

I sincerely thought I could tell mornings from evenings by light alone, until I congratulated a friend on a great capture of evening light and he told me the shot was taken in the morning. Did some research after that.

Based on Raleigh scattering only and one time stamp only the answer is, I think... Maybe.

In the morning, if there is less dust, then there would be different Raleigh scattering.
