At macroshooting necessary promotion of an objective pays off under tables depending on the demanded scale. Shooting of small objects is full-scale possible, if an objective will put forward on a double focal length.

In normal position, at navodke on ' infinity ', the main plane of an objective is removed from a film precisely on focal length size, therefore and the set of lengthening rings should be same. Such shooting concerns special kinds for here it is required settlement to define by svetosilu an objective and depth of sharpness. Both that, and another strongly decreases with scale increase, for example, shooting on the scale of 1: 1 demands endurance increase in 4 times. To direct at sharpness it is more convenient not rotation of a ring of focusing, and by moving of all device along an optical axis.

For shooting with increase that is when the subject image more than he, often recommend to overturn an objective and to establish its forward lens to a film. If the objective symmetric or is specially calculated for macroshootings, it to do it is not necessary.

To receive the sharp image, very short endurances as speed of moving of the image concerning a photographic material increases proportionally to shooting scale are necessary.
