    In the case of large format, 4 x 5 inch films can record approximately 298.7 million pixels, and 1,200 million pixels in the case of 8 x 10 inch film. However, as with a digital system, poor optical quality of lenses will decrease the resolving potential of a film emulsion. [7] [8] [9]

  5. Pixel aspect ratio - Wikipedia

    en.wikipedia.org/wiki/Pixel_aspect_ratio

    The aspect ratio of the pixels themselves is known as the pixel aspect ratio (PAR) – for square pixels this is 1:1 – and these are related by the identity: SAR × PAR = DAR. Rearranging (solving for PAR) yields: PAR = DAR / SAR. For example: A 640 × 480 VGA image has a SAR of 640/480 = 4:3, and if displayed on a 4:3 display (DAR = 4:3) has ...
