These photos are of patterns created by moving water at the coast, and one of clouds.They have not been altered apart from a little tweaking of levels/ contrast.
When teaching about abstract art (painting), many of the students initially had the idea that the artwork had to be created completely from the imagination. While that is one way, there are plenty of natural sources of inspiration. It is more about looking for pattern and shape and removing the need to identify a subject. These photos were taken because I loved the patterns. shapes, colours, contrasts and light. They would be good references for the painter of abstracts
