In this tutorial we discuss the depth of field (DOF) and deal with such questions as: "How sharp is the image at the DOF limits? Can you trust DOF scales? What aperture should you choose for optimum sharpness when the subject spans a range of distances?"

In this page we discuss lens testing (actually, testing complete photographic systems) using the Koren 2003 lens test chart, which has continuously varying spatial frequency. You can download, print and assemble it yourself. This approach is primarily intended for film images, but Imatest Log frequency analyzes digitized images of the chart described further.

In this page we discuss printers and prints and how to characterize their sharpness and resolution. We deal with the issue of how many pixels per inch are required for a sharp print.
