Genius.
There are a lot of flashes out there that strive to be dark-surreal (Not to be overly harsh on Firth, who I am a fan of but many of his flashwork nowadays seem hardly genuine.. as if he's aiming just for shock value and not content) and so few of out that lot actually succeed in giving me chills. However, this flash does and without the use of excessively dingy and dark colors.
It's all rather Dali-esque.
