Here’s a photo of the Sifto Salt Mine in Goderich, Ontario. I took it maybe 45 minutes before sunset, down at a boat launch where I lay on a small wooden dock so I could get as low as possible to the water.
I like the simple blocks of blue and their reflection in the water. It made me think the image might work well as a compressed png file, so I tried an experiment, first with eight colours, and then with four. You can see the results below:
Then I thought it might work well as a series of coloured blocks, a la Warhol.
