The goldilocks speed. ISO 400 is fast enough for handheld shooting in questionable light, slow enough for gorgeous grain and sharp detail, and versatile enough to handle whatever conditions the British weather throws at you. This collection gathers the workhorse films that professional and amateur photographers alike load when they need something that just works. From legendary Kodak Tri-X and Ilford HP5 to vibrant Kodak UltraMax and versatile Candido 400. Push it, pull it, shoot it at box speed like you're supposed to. ISO 400: the speed that covered wars, revolutions, and your weekend trip to Brighton.
