Colour at sunset vary dramatically from minute to minute, and with different exposure settings. This photograph is directly from the camera with absolutely no modification at all. Did it look like this at the time? Well that’s up to the viewer’s perception of the brightness and colours at the time. It’s one of those interesting things about photography, how a camera captures a specific set of colours where the human brain and eye would experience a whole wider range of “pictures” of the scene simultaneously, or as you look from brighter to darker areas of the landscape.
I called this “Infinite Sun” because to me it looks like the Sun is infinitely far beyond the silhouette ridge line, and the sky an infinite variation of colour. I also like the quirky nature of the title, in that while the sun looks infinitely distant and the colours infinitely varied, the sun is actually setting and will be gone very soon, being most definitely finite you could say. I like that contrast.
