One of my manic disorders forces me to see faces in all kinds of rock formations.
The varied geological nature of Corsica, together with heavy erosion due to wind and water, provides ample material.
Sometimes, sunlight helps, too.
I am sure that today, after more than 20 years, these rocks are better preserved than the negatives I had to deal with. Besides the usual dust and scratches, some of them have deteriorated beyond help. I have stored all of them in proper sleeves and under dry conditions. Still, I noticed large speckled areas on some of them that clearly were not present 20 years ago.
