Standard SMPTE 195 specifies the projectable image area for 1.85:1 "flat" as 0.825 x 0.446 inches.Standard SMPTE 59 specifies three different 35mm Camera Aperture Image areas: Style A 0.864 x 0.63 inches ("Academy") Style B 0.864 x 0.738 inches (Scope) Style C 0.981 x 0.735 inches (full frame) Most "flat" productions shoot with the full frame aperture, to reduce the risk of "hairs in the gate", while composing for the 1.85:1 projectable image area. So if contact printing is used for all printing stages, the image height is 0.735 inches, even though only 0.446 inches is intended to be projected on the screen. "Hard Mattes" are rarely used in the camera, to give later flexibility when the images are transferred to video. Good practice "protects" the top and bottom of the image, so that mike booms or other production hardware doesn't show up on the screen, even if the projector is poorly framed. A "hard matte" can be introduced during optical printing, either to force correct framing, or as a consequence of some scenes having optical or digital effects. Digital effects often are output with a matted frameline, since it would cost extra to "render" image area that is not intended to be projected. So that is why you sometimes see prints having a variety of frameline thicknesses, and need to frame carefully to avoid showing the framelines in some scenes. ------------------ John P.
