Very often, an abstract photo is a macro photo. The principle is to see big what is small.
Here is an interesting example that I was lucky enough to capture.
So, what do you see, what do you imagine? A crocodile eye maybe? No, perhaps a marble?
Is it the photographer you see in the reflection?

Well, it’s only a big bubble on a tar plate heated by the sun, on which the trace from his tires has been left.
I love that picture.
Yeah, there is not only cars on our roads.
