You would be surprised at where you can find a abstract made by nature.
I found these abstracts (click blue writing to find more photographs natural abstracts )
while out walking with my Dog. they are all captured in frozen muddy puddles. the ice and mud produced a natural abstract with some pretty patterns.
I woke up to a very cold and heavly frosted morning. So with camera in hand and set to macro The dog and I set out to find out what sort of textures and and abstract shapes would could find naturally while on our walk.
These are all found in our local fields.
