A good cell phone camera with typical pixel size 1.1 μm (Samsung A8) would have about 3 times worse SNR due to shot noise than a 3.7 μm pixel interchangeable lens camera (Panasonic G85) and 5 times worse than a 6 μm full frame camera (Sony A7 III). Taking into consideration the dynamic range makes the difference even more prominent.
The alternative Super series, denoted SnR, nR Plus or nR+, has an aspect ratio of 3∶2 (or as close as possible) and thus provides a better fit for standard 135 film (35 mm) at sizes of 8 inches or above. 5R is twice the size of a 2R print, 6R twice the size of a 4R print and S8R twice the size of 6R. 4D/6D is a newer size for most consumer ...
Find the optimal distance for a given screen. Example: for a 4K UHD screen 140 cm high (112 inches diagonal), the optimal distance is 140 × 1.6 = 224 cm. Find the right screen size. Example: for a 1080 HDTV used at a distance of 250 cm, you need to find a screen whose height is close to 250 / 3.2 = 78 cm (63 inches diagonally).
The size of a screen is usually described by the length of its diagonal, which is the distance between opposite corners, typically measured in inches. It is also sometimes called the physical image size to distinguish it from the "logical image size," which describes a screen's display resolution and is measured in pixels. [1] [2]
Common in large and medium format photography ('6x7' cameras, actual size 56 mm × 70 mm (2.2 in × 2.8 in)), which fits the common print paper size of 8 in × 10 in (20.3 cm × 25.4 cm) without cropping and is still in common use for prints from digital cameras.

The French National Print Office adopted a point of 2 ⁄ 5 mm or 0.400 mm in about 1810 and continues to use this measurement today (though "recalibrated" to 0.398 77 mm). [ 21 ] [ 22 ] [ 23 ] Japanese [ 24 ] and German [ 9 ] [ 16 ] [ 18 ] standardization bodies instead opted for a metric typographic base measure of exactly 1 ⁄ 4 mm or 0.250 ...
