What is the 4:3 aspect ratio?<\/h2>\n\n\n\n

The 4:3 aspect ratio refers to the ratio of width to height of an image.<\/p>\n\n\n\n

4:3 is a type of aspect ratio which is self-defining, the ratio refers to 4 units high by 3 units wide. <\/p>\n\n\n\n

If we divide 4 by 3, we get 1.33. This number indicates that to have an equivalent aspect ratio, the division should yield a result of 1.33, such as 8:6.<\/p>\n\n\n\n

It is an almost rectangular ratio, which exists and has presence due to the sensors of old film cameras. These cameras were equipped with full frame 35mm sensors, producing this aspect ratio when capturing the image.<\/p>\n\n\n\n

How it emerged <\/h2>\n\n\n\n

The 4:3 aspect ratio emerged with the advent of film cameras and their 35mm sensor.<\/p>\n\n\n\n

It was William Kennedy Dickson<\/a> who, after his attempts in Thomas Edison<\/a>‘s laboratory, designed a sensitive film capable of being projected with a kinetoscope<\/a>.<\/p>\n\n\n\n

This film had dimensions of 2.4cm wide and 1.8cm high, which corresponds with the 4:3 aspect ratio or 1.33:1.<\/p>\n\n\n\n

This design was not marketed until 1909 by the Motion Picture Patent Company, which made the 4:3 aspect ratio the standard for cinema. This standardization within cinema led to it being adopted as a universal format for television years later.<\/p>\n\n\n\n

4:3 Aspect Ratio in Photography<\/h2>\n\n\n\n

The 4:3 aspect ratio in photography<\/a> is one of the most used. It is very important to be aware of the format and aspect ratio when taking a photo. The framing and development (in the case of analog photography) depend directly on these.<\/p>\n\n\n\n

The 4:3 aspect ratio in photography has less dynamic frames<\/a>, this is because this aspect ratio has no dominant horizontality. The dynamism of an image is directly conditioned by the dominance of its horizontal axis.<\/p>\n\n\n\n

Other photographic formats with little or no dominance of the horizontal axis are 5:4, 3:2, and 1:1 (completely square).<\/p>\n\n\n\n

The most used photographic formats with horizontal dominance are 16:9 and 2:1, and the most used vertical formats are 2:3 and 3:4.<\/p>\n\n\n\n
