This is just a short continuation of my earlier post concerning the communication of era in cinema. The actual printing technique, which produces the sepia-style affect found in films such as O’Brother, Where Art Thou? (2000) and Saving Private Ryan (1998), is called Bleach Bypass.
‘Bleach Bypass printing is a process that involves leaving the silver grains in the emulsion layer rather than bleaching them out. This has the effect of desaturating the colour because it is akin to adding a layer of black-and-white to a colour negative’ In both Saving Private Ryan and O’Brother, Where Art Thou? ‘the desaturation of the colour [by process of bleach bypass]. combined with the… brown palette of the settings… recalls the sepia tones that are used in historical photographs and thus contributes to the films’ emphasis on memory’ and the communication of a by-gone era.1
