Camila Freitas Posted February 16, 2007 Share Posted February 16, 2007 Hi Is it necessary to compensate for exposure when you shoot S16 for an optical blow-up? Thank you Camila Freitas Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted February 16, 2007 Premium Member Share Posted February 16, 2007 The exposure for the blow-up to a dupe element is a separate thing from the exposure for the original camera negative. Optical printer operators wedge test and determine the right exposure to create a new film element with the right density. Usually they are working with a color-timed, contact-printed 16mm IP so there is only an overall exposure for the reel (not scene-to-scene corrections) when making the 35mm dupe negative in an optical printer. However... A well-exposed, i.e. denser-than-normal, negative helps reduce grain and improve blacks, which makes for a better blow-up. Most people do this by rating the film stocks slower than normal, like by 1/3 or 2/3's of a stop (1/3 of a stop is farily negligible however -- 2/3's of a stop is better.)

Does that also apply to a s16-HD-35 blow-up? What differences do you consider most important between the two routes? Many thanks, Camila Link to comment Share on other sites More sharing options...

Many thanks, Camila Hi, Slight overexposure is always a good thing, regardless of post route. Stephen Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted February 16, 2007 Premium Member Share Posted February 16, 2007 Yes, doing D.I.'s I've still found that a slightly denser-than-normal negative is better, although a little less critical than for direct printing and optical work.
