A picture of the King's collection, in the British library. The King's collection is an impressive set of several floors of continuous shelves of ancient books in the center of the building. I took a picture, knowing that I couldn't find a foreground, but with the idea of a prototypical, almost clip-art, image of book shelves. As I am a scholar, bookshelves have a strong allegorical meaning. This image might be a good backdrop, or desktop background.
Avoiding a dull composition is hard. I hope that I didn't fully fail. I used the regularity of the shelves to frame the picture, but I used the few light-colored books to break this regularity.
In terms of post-processing, my main actions were to make sure that the shelves were really dark, to highlight a bit more the light-colored books, to shift the colors a bit to the yellow. Also, I used a bit of vignetting, to create the impression of light in the center of the image. Finally, I increased a bit the contrast (clarity filter)
Technically, I post-processed with Darktable. I used tone curves, color adjustment, and split-toning to give a bit of yellow to the highlights.
