wealth of the characters. Daytime serials often foreground other sumptuous elements of set decoration; presenting a "mid-shot of characters viewed through a frame of lavish floral displays, glittering crystal decanters or gleaming antique furniture". Few U.S. daytime soap operas routinely feature location or exterior-shot footage (Guiding Light began shooting many of its scenes outdoors in its final two seasons). Often an outdoor locale is recreated in the studio. Australian and U.K. daily soap operas invariably feature a certain amount of exterior shot footage in every episode. This is usually shot in the same location and often on a purpose-built set, with new exterior locations for particular events. The visual quality of a soap opera is usually lower than prime time U.S. television drama series due to the lower budgets and quicker production times. This is also because soap operas are recorded on videotape using a multi-camera setup, unlike prime time productions that are usually shot on film and frequently use the single camera shooting style. Because of the lower resolution of video images, and also because of the emotional situations portrayed in soap operas, daytime serials make heavy use of close-up shots. Programs in the United States did not make the full conversion to high definition broadcasting until September 2011, when The Bold and the Beautiful became the last soap to convert to the format; One Life to Live was an exception to this, as it continued to be produced and broadcast in standard definition – albeit in the 16:9 aspect ratio – until the end of its run on ABC in January 2012. Soap operas have idiosyncratic blocking techniques. In one common situation, a romantically involved couple starts a conversation face-to-face, then one character will turn 180° and face away from the other character while the conversation continues. This allows both characters to appear together in a single shot, and with both of them facing the audience. This is unrealistic in real life and is not frequently seen in film or on television outside U.S. daytime serials, but it is an accepted soap opera convention, sometimes referred to as a "two shot West". Because of the escapist tone of the genre and due to the large number of cast members employed by each program (usually totaling around 30 to 35 actors for hour-long soaps, and 15 to 25 for those lasting a half-hour), daytime soap operas have traditionally listed
