I took this photograph while on a weekend photography course in Abu Dhabi a few years ago. The colour original isn’t up to much: an over-exposed (very bright sunlight) pale yellow section of what, apart from a line of these tilted squares, was a pretty nondescript wall.

However, this monochrome version is, in my view, a lot more interesting: the shape itself is emphasised – helped by the vignetting I added – and the whole thing is somehow much ‘grittier’ thanks to the greater contrast available in black & white.
