WebApr 28, 2024 · Assuming accurate meta data (EXIF) is present, it would be possible to determine possible camera model resolutions. Without metadata it's a statistical guess from common available possibilities. What you refer to as "True Resolution" is a difficult concept. To start with, digital cameras don't have pixels in the first place, they have sensors. WebThe higher the resolution, the smaller the detail that can be resolved from an object. It is influenced by pixel size, magnification, camera optics and the Nyquist limit. Camera resolution can be determined by the equation: Camera Resolution = ( Pixel Size Magnification) * 2.3. Where 2.3 compensates for the Nyquist limit.

WebSep 25, 2024 · The Rayleigh Criterion supplies the maximum theoretical resolving power in lines per millimeter. Resolving Power = 1392 ÷ f-number. The value 1392 is about the center of the photographic pictorial range of colors. f/1.4 = 994 lines per mm. f/2 = 696 lines per mm. f/2.8 =487 lines per mm.
