A solution to resolution – Part 2 (Image Size explained)
A typical consumer DSLR camera might come with image resolution of 24.3 MP or 24 megapixels. So exactly what does that mean anyway? It means that at the highest quality setting – Camera Raw or the .jpeg “L” large setting – an image file can be produced that contains 24,160,256 pixels. This will, at an input resolution of 300 ppi (Nikon D750 default input resolution) produce an acceptable 11 x 17 inch print at 360 ppi.
