NOTES ON FOCUSING

Camera Shake; Close-up photography poses

several problems not encountered in general

photography. One of these is sensitivity to

vibration—the magnification of the image is so

high that even slight displacement during
shooting results in a blurred image. Therefore,

the use of a tripod is recommended at all

times, with shutter actuated via cable release.

In this respect, the convenient, 360° rotatable

tripod mounting collar on the PN ring will
prove useful.

Close Working Distances; At high reproduction

ratios encountered during close-up shooting,

depth of field decreases drastically. This con
dition can be partially compensated for by
stopping down the lens. But at very close

working distances, an extremely shallow depth

of field is inevitable. Careful placement of the
camera will be necessary to ensure that the

important surfaces of the subject are in the

same zone of sharpness.
