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 ...
35 mm film is scanned for release on DVD at 1080 or 2000 lines as of 2005. The actual resolution of 35 mm original camera negatives is the subject of much debate. Measured resolutions of negative film have ranged from 25–200 LP/mm, which equates to a range of 325 lines for 2-perf, to (theoretically) over 2300 lines for 4-perf shot on T-Max 100.
For example, the Nikon D3 and D700 cameras' nominally full-frame sensors actually measure 36 × 23.9 mm, slightly smaller than a 36 × 24 mm frame of 35 mm film. As another example, the Pentax K200D 's sensor (made by Sony ) measures 23.5 × 15.7 mm, while the contemporaneous K20D 's sensor (made by Samsung ) measures 23.4 × 15.6 mm.
The digital publishing industry primarily uses pixels per inch but sometimes pixels per centimeter is used, or a conversion factor is given. [ 21 ] [ 22 ] [ 23 ] The PNG image file format only allows the meter as the unit for pixel density.

Comparison of screen sizes by width, height, diagonal, area, and aspect ratio. On 2D displays, such as computer monitors and TVs, display size or viewable image size (VIS) refers to the physical size of the area where pictures and videos are displayed.
This example shows an image with a portion greatly enlarged so that individual pixels, rendered as small squares, can easily be seen. In digital imaging, a pixel (abbreviated px), pel, [1] or picture element [2] is the smallest addressable element in a raster image, or the smallest addressable element in a dot matrix display device.
In photography, exposure is the amount of light per unit area reaching a frame of photographic film or the surface of an electronic image sensor.It is determined by shutter speed, lens f-number, and scene luminance.
