length are handled exponentially in depth-of-field calculations. Depth-of-field changes
cannot be computed using a linear variable such as the crop factor of the camera.
1.F – Conclusion: Taking Advantage of Depth-of-Field in Your Photography
Depth-of-field can be used creatively to emphasize or deemphasize elements in your
photographs. If you are attempting to achieve overall image sharpness, focusing on the
hyperfocal distance maximizes depth-of-field from the closest possible distance to infinity.
The exclusive variables photographers can use at capture to control depth-of-field are lens
focal length, lens aperture and focusing distance. By changing any one or all of these
variables, you can change the depth-of-field.
The complexity of depth-of-field calculations can make taking advantage of depth-of-field
when shooting difficult. In the past, to figure the correct f/stop to use, determine your focus
point or figure out what depth- of-field you were actually getting you needed to carry around
reams of lens and f/stop tables or make your best guess.
The accompanying ExpoAperture
2 Depth-of-Field Guide eliminates the inconvenience of
carrying around those tables, doing mathematical calculations or guessing incorrectly. The
Guide quickly solves depth-of-field calculations, freeing you to focus on the creative aspects
of your shots.
