Including the Specials, there have been 179 x 45 minute Episodes to date over 7 seasons since 2004 with a budget of around $2m per episode.
All episodes prior to the 8th series were originated on 35mm film stock. Testing of the Alexa commenced during the 7th series in the Spring of 2011.
Lowell Petersen has been working on the series since the first season. Up until now the episodes were shot on Arriflex cameras with Kodak 35mm film stock. Lowell has commented that the goal for the show has always been "to keep the photography interesting and contrasty" while also bringing out the performers' beauty.
“Many lighting situations combine extremes of bright, hard sunlight in certain portions of the frame with the subtlety of broad and soft sources on the talent. The show is shot single-camera style with a B-camera added where necessary and there is also a great deal of Steadicam work”.
