An update in 1970 (PH22.106-1971) changed the aspect ratio to 2.39:1 in order to make splices less noticeable. A SMPTE specification for anamorphic projection from 1957 (PH22.106-1957) finally standardized the aperture to 2.35:1. After 1952, a number of aspect ratios were experimented with for anamorphic productions, including 2.66:1 and 2.55:1. The motion picture industry convention assigns a value of 1.0 to the image’s height an anamorphic frame (since 1970, 2.39:1) is often incorrectly described (rounded) as 2.40:1 or 2.40 ("two-four-oh"). With a space designated for the standard optical soundtrack, and the frame size reduced to maintain an image that is wider than tall, this resulted in the Academy aperture of 22 mm × 16 mm (0.866 in × 0.630 in) or 1.375:1 aspect ratio. The film itself is 35 mm wide (1.38 in), but the area between the perforations is 24.89 mm × 18.67 mm (0.980 in × 0.735 in), leaving the de facto ratio of 4:3, or 1. The universal standard (established by William Dickson and Thomas Edison in 1892) is a frame that is four perforations high. In motion picture formats, the physical size of the film area between the sprocket perforations determines the image's size. With television, DVD and Blu-ray Disc, converting formats of unequal ratios is achieved by enlarging the original image to fill the receiving format's display area and cutting off any excess picture information ( zooming and cropping), by adding horizontal mattes ( letterboxing) or vertical mattes ( pillarboxing) to retain the original format's aspect ratio, by stretching (hence distorting) the image to fill the receiving format's ratio, or by scaling by different factors in both directions, possibly scaling by a different factor in the center and at the edges (as in Wide Zoom mode). Other aspect ratios, such as 5:3, 5:4, and 1:1 (square format), are used in photography as well, particularly in medium format and large format. In still camera photography, the most common aspect ratios are 4:3, 3:2, and more recently found in consumer cameras, 16:9. Other cinema and video aspect ratios exist, but are used infrequently. 7:1), universal for high-definition television and European digital television. 3:1), the universal video format of the 20th century, and 16:9 (1. Two common videographic aspect ratios are 4:3 (1. The most common aspect ratios used today in the presentation of films in cinemas are 1.85:1 and 2.39:1.
