“ London fog used to be a thick, pea-souper full of mystery and Jack the Ripper. Modern London fog is more of a "misty inconvenience." It's not thick enough to be dramatic, just enough to make everything look slightly out of focus and to give your hair that "just-stepped-out-of-a-shower" look without the benefits of cleanliness. It hangs in the air with a vague purposelessness, diffusing the streetlights into fuzzy haloes and making the number plates of buses unreadable until they are upon you. It's the atmosphere's version of a soft-focus lens, presumably to make the relentless grey more aesthetically pleasing on Instagram, where it's tagged #atmospheric #moody.
