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

Directors wishing to portray a definitive era in a movie use certain techniques which also produce nostalgic emotions of a sense of authenticity which are both beneficial to cinema as art and a commercial product. In Films such as O’ Brother, Where Art Thou? (2000) the colour brown is used to produce an affect of a faded and lost past. This makes the film similar to looking at a very old photograph aged sepia-brown. This imbues the whole form of the film with a sense of a by-gone era. The use of browns also strips away, or inhibits, the editors’ [or whoever] ability to produce a slick glossy product as sepia-brown ensures an aesthetic affect which communicates a reality opposed to the whole editing process.
Another common technique, used more and more regularly due to the financial importance of a film having a commercially viable soundtrack, is the use of music. This is normally non-diegetic however occasionally this is a main part of the diegesis. One movie that uses music to produce a sense of era is Donnie Darko (2001). All through the film a classic eighties soundtrack is played which injects a sense of place, time and atmosphere. Using music of a definitive era helps communicate the atmosphere that the director wants as they can use a specific genre of music to imbue the film with an emotion. The music of the seventies can both be used to communicate a riotous sense of anger with a punk soundtrack and create a sense of love and romance with a use of disco soundtrack.
