===Determining 35mm aspect ratios for projection=== | |||
For some [[film gauges]], the aspect ratio will be obvious. 16mm is rarely anything but full frame (though there are variations - see above). Other small gauges are rarely anything but their native aspect ratios. [[35mm]], however, can be complicated. | |||
* The first way to determine the aspect ratio is to find out when the film was made and using your knowledge of film history, assign its aspect ratio. | |||
* The second and complementary way is to look at a frame of the print and using the different aperture plates, try to eyeball which looks best. | |||
** It's often best to look at the [[framing]] of the opening credits, or at a scene with [[subtitles]]. | |||
Be aware that there are always exceptions to any these rules. And: don't just trust IMDb! | |||
