Normally I find post-processing my images very therapeutic, but this one drove me nuts, mostly because I almost got it looking how I wanted it (striking blue light through the glass offset by the chrome inside this stairwell), but just couldn't quite get it right.

So, instead, here's a moodier colourised version instead.
