Depth of field - Wikipedia

A macro photograph showing the defocused effect of a shallow depth of field on a tilted page of text This photo was taken with an aperture of f/22, creating a mostly in-focus background. The same scene as above with an aperture of f/1.8. Notice how much blurrier the background appears in this photo. The depth of field (DOF) is the distance between the nearest and the furthest objects that are in a

『When the 35 mm lens above is set to f/11 and focused at approximately 1.3 m, the DOF (a “zone” of acceptable sharpness) extends from 1 m to 2 m.』

" For a given subject magnification, increasing the f-number (decreasing the aperture diameter) increases the DOF; decreasing f-number decreases DOF."
