DIGITAL CAMERA FLEXIBLE DEPTH OF FIELD CALCULATOR – Cambridge in Colour, Sean T. McHugh
VERY EXTENSIVE.

Available in English, French/Français, German/Deutsch, Italian/Italiano, Portuguese/Português & Russian.

Flexible Depth of Field Calculator

• • • • “…is more flexible than that in the depth of field tutorial because

• • • • it adjusts for parameters such as viewing distance, print size

• • • • and eyesight–thereby providing more control over what

• • • • is “acceptably sharp” (maximum tolerable circle of confusion)…”

• • • • “…As the viewing distance increases, our eyes become less able

• • • • to perceive fine detail in the print, and so the depth of field

• • • • increases (max. CoC increases). Conversely, our eyes can perceive

• • • • finer detail as the print size increases, and so the depth of

• • • • field decreases. A photo intended for close viewing at a

• • • • large print size (such as in a gallery) will likely have a
