The basic way to work would be to generate a test strip with intervals one F-stop apart. Viewing a 10' x 8' (25cm x 20cm) photograph at this distance would fulfil these requirements. The F-Stop Printing Calculator assumes you need to establish 1/4 stop increments (+ or up to 3/4) of the base time you have entered and, either generate a new time, or an increment of an F-stop if you are burning in, or making a more precise test strip. The calculator above assumes that the resulting photograph will be viewed as an image with a diagonal measurement of about 30cm (12 inches) viewed from a distance of 25cm (10 inches). The most common formats are included.Īssumptions for the calculations of DOF are subjective. This calculator is designed specifically for roll films that were used in Art Deco and vintage cameras. This is useful for landscape photography to get as much foreground in focus as possible and still keep elements at infinity in focus. When you focus at the hyperfocal distance the in-focus field will stretch from half the hyperfocal distance to infinity. If you focus at infinity, the in-focus field will stretch from the hyperfocal distance to infinity. The distance at which you should focus to produce the greatest depth

Higher f-numbers (small aperture) are used more in landscape photography. This is frequently used for nature photography and portraiture because background blur can be aesthetically pleasing and puts the viewer's focus on the main subject in the foreground. The depth of field increases with f-number which means that photographs taken with a low f-number (large aperture) will tend to have subjects at one distance in focus, with the rest of the image (nearer and farther elements) out of focus.
