Hmm, I’ll have to keep this in mind as I observe reflections from now on. I don’t know any science behind it if there is any. From what I can think of right now, it seems like there would be 4 main factors:
1) The stillness of the surface (non-flowing bodies of water, amount of wind)
2) The direction of light on the object being reflected (a clear object will reflect clearly…I think of clear objects as being under side lighting vs back lighting)
3) Darkness of the water (I’m thinking like Bahamas vs Okefenokee, crystal clear vs dark, murky)
4) Cleanness of the surface
