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. Web22 sep. 2016 · You need to know these key points: Image resolution determines the size at which you can produce high-quality prints. A general guideline is to aim for 300 pixels per linear inch (ppi). For onscreen photos, you need very few pixels. Resolution affects the display size of digital photos, but does not affect picture quality.
