I thought it was about music (Bach). Beautiful, precise and eternal.
I like the change of the direction of the textures with the band of light running between them. Nice shades of brown with the velvety feel. Overall great photo. 1x candidate.
Is it just long exposure or also multilayer? (I am still trying to learn)
PS Just realized a fugue is made of 3 parts - this image is very clever too
I agree full-hearted with "wonderful" but this is not abstract to me if one defines abstract by its first dictionary definition: "Considered apart from concrete existence".
In psychiatry "fugue is a dreamlike altered state of consciousness, lasting from a few hours to several days, during which a person loses his memory for his previous life and often wanders away from home"
But this is a splendid representation of TERRA MOBILIS
