be aligned properly as light sources that are in the center of the full frame appear slightly lower than usual in 2.39 and corner fall-offs and other distortions are not optically centered properly. Also in wide shots, there is too much footroom and not enough headroom and extreme close ups of actors faces as well as their foreheads are still cut off but more picture is gained below the frame. As 16:9 televisions increased in popularity, it became more practical for productions to use the "common center" extraction, which frames across the center of the film, although a "common third" extraction is used if directors want similar headrooms between 2.39 & 16:9 versions. The Super 35 format has also gained attraction for use in large budget visual effects driven films as the unused frame areas outside 1.85/2.39 can be used by VFX artists to film different visual effects elements with spherical lenses and more freedom to move within the frame with 2D and 3D tracking. Details Super 35 is a production format. Theatres do not receive or project Super 35 prints. Rather, films are shot in a Super 35 format but are then – either through optical blowdown/matting or digital intermediate – converted into one of the standard formats to make release prints. Because of this, often productions also use Super 35's width in conjunction with a 3-perf negative pulldown to save costs on "wasted" frame area shot and accommodate camera magazines that could shoot 33% longer in time with the same length of film. If using 4-perf, the Super 35 camera aperture is 24.89 mm × 18.66 mm (0.980 in × 0.735 in), compared to the standard Academy 35 mm film size of 21.95 mm × 16.00 mm (0.864 in × 0.630 in) and thus provides 32% more image area than the standard 35-mm format. 4-perf Super 35 is simply the original frame size that was used in 35 mm silent films. That is, it is a return to the way the film stock was used before the frame size was cropped to allow room for a soundtrack. Super 35 competes with the use of the standard 35 mm format used with an anamorphic lens. In this comparison, advocates of Super 35 claim an advantage in production costs and flexibility; when used to make 1.85:1 or 2.39:1 theatrical prints and the ability to format the film for TV, detractors
