Wratten is a brand name from Kodak used for their series of coloured gelatin correction and conversion filters. There’s a wide range – each one identified by its Wratten number. The filters can be held or taped in front of the lens (or flash). Alternatively you can buy a gelatine filter holder for most filter systems for a neater way to attach the filter to the lens.
