Micro photography - tears

[Three Roses]

Stumbled upon an interesting article re a photographer who has managed to capture photos of different types of tears - for example, tears of joy, grief, etc - which show that these different tears are also visually different. There is a brief article explaining her work. https://www.smithsonianmag.com/science-nature/the-microscopic-structures-of-dried-human-tears-180947766/
