Thank you! The low angle of the sun helped, I think.

I like 'em both, Rob, but I prefer the first one - to my 70-year-old eyes it has more detail and texture. Good stuff.

I like the first one best. The warmer color and like sailor, the detail and texture. And my eyes are only 58 years old.

Thanks everyone! The first one captures the lens effect better, for sure. One thing I found curious was that the undersides of the leaves were hydrophobic but the upper leaf surface wasn't.

Rob, I've noticed the same thing myself. I am (or was before I retired) an organic/polymer chemist - material scientist, so I know a lot about what makes something hydrophobic or hydrophilic . . . . but . . . . . . I know nothing about plants. Mother nature has a reason for this behavior, and we need a botanist to explain it to us.

Cool! Presumably a lot of research goes into making surfaces shed water (hydrophobic) like coatings for car paints and raincoats etc. I assume there's situations where you want surfaces to be hydrophilic too, like spraying plants with detergents to help them absorb things. From what I remember of university biology, the stomata on leaves are on the underneath of the leaf so that they're in the shade. It's the stomata through which they release oxygen and water. So I guess it makes sense for the underside to be hydrophobic - otherwise rainwater clinging to the leaf would make it hard for the cells to function. Some leaves are hydrophobic on the top - like rainforest plants, and African violets. I guess these deciduous trees evolved in areas where they like the rain and don't usually get too much of it.
