How do you calculate image resolution

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.
