Another image of the wall, taken at about the same time. The tree is the same as in the first image. The focal length is different and so is the direction of view. The sky is not as deep blue as in the first image. This is partly a result of direction and focal length, and, of course, the blue in the first image looks exaggerated.
Can I tell after five years? No way. Photo processing is guesswork, and that’s ok.
