  Focusing book
Focusing, the technique described in the pages of this book, is uniquely suited to our turbulent times when so many old forms are crumbling and old roles are vanishing.
Focusing is a key to personal momentum and unfolding, a dynamic process that can guide us through the tricky mazeways of a new world.
Focusing grew out of the observation by Gendlin and his co-workers that many people were not being helped by traditional therapy.

 THE FLAW IN ALL AUTO-FOCUSING CAMERAS
In fact, they all have a built-in, unavoidable error that makes accurate focusing impossible in all photographs except those in which the most important subject-point is in a flat area that is parallel to the camera, and in the center of the picture.
If the lens is focused so that the focal-plane is exactly on the pupil of that eye, the whole picture will take on a quality called "plasticity" (the effect of three-dimensionality on a two-dimensional surface), the apparent depth-of-field will be greater, and there will be less impression of graininess.
All manual focusing systems that are located in the center of the ground-glass suffer from this same built-in error because of the inability to focus and frame the picture simultaneously.

 Focusing Tips
Focusing through the camera using the focusing screen is probably the most common way novice astrophotographers focus their shots.
It is important that this focusing screen provide both a surface for the light to be focused upon while at the same time be clear enough for the image to be seen in the viewfinder which is on the other side of the screen.
Knife edge focusing is used by all the top astrophotographers in the world because it consistently achieves an unquestionable precision of focus without relying on one's ability to focus one's eye well in near total darkness, and does not rely on the questionable focus achieved looking through ground glass.

 What is Focusing?
Focusing is a kind of inward bodily attention that a few people have naturally, but which most people don't yet know.
Focusing was named and developed by Dr. Eugene T. Gendlin, Ph.D. at the University of Chicago out of a philosophical background as well as a clinical and psychological research.
The Focusing Institute was founded in 1986 as a non-profit organization whose purpose is to help make Focusing available to the public and to the International scholarly community through teaching, research and written materials.

It is necessary to critically focus the viewing magnifier on the pattern on the front of the focusing screen first so as to hold the attention of the observers eye to that focal plane.
It is assumed in this discussion that the reflex viewing focusing screen is parfocal with the actual film plane so that the front surface of the focusing screen represents the focal plane of the actual image that falls, during exposure, on the film plane.
To give the best possible focus and brightest image the focusing screen is of the type that has a clear central spot and a cross hair engraved on the bottom of the screen exactly in the focal position of the film.

 APPLICATION OF RF CROSSED LENSES FOR BEAM FOCUSING IN LINAC
The focusing strength in the structures decreases with enhancement of particle energy a fact that results in increase of transit time of the focusing period with a distance along the linac.
Note, that the focusing properties of the FODO period weakly depend on a configuration of the drift tubes and are mainly determined by fields of the crossed lenses.
It is possible to reduce a number of the crossed lenses in the focusing period and, consequently, to increase acceleration rate in main part of the linac through decrease of RF defocusing by change from autophasing to sign-alternating phasing.

 Focusing questions & answers
Focusing is a close cousin of the person-centred approach begun by Carl Rogers with whom Gendlin was a colleague for many years.

 Focusing Screens
Interchangeable screens are useful because the astrophotographer will often wish to replace the original screen with a brighter one for focusing and framing for astrophotography.
Most focusing screens are composed of two main parts, a plastic fresnel or fine matte screen, and a glass top section that is curved.
Despite the darkness from what appears to be vignetting on the screen, you can still focus accurately in the center of the screen with a wide angle lens, and none of this apparent vignetting shows up on the film.

 Focusing by Knife Edge
This ensures that the camera is focused where the film's emulsion will be when it curls backward off the inner rails because of the film's natural curl from being wound up in the cassette, and presses back against the pressure plate.
The knife edge focuser is made of a piece of film and a piece of glass scavenged from a Gepe glass slide mount.
If you have a scope with severe mirror slop and flop, you will have to investigate solutions for these problems or knife edge focusing may not work perfectly because the focus can change after using the knife edge when the scope is moved back to the object.

Because of the difficulty of sighting directly through the focuser for knife edge focusing, Mark told me that once he calibrated it against the camera back, he only used it to verify that he was achieving good focus with his normal ground glass focusing.

 Focusing System
Cameras with automatic focusing systems usually measure the distance to the center of a finder's view.
The guiding principle for establishing rules of this automatic focusing system is that the likelihood of an object being at medium distance (typically 10 meters) is high, and becomes very low as distance increases (say, more than 40 meters).
For professional photographers it may be inappropriate to provide strictly automatic camera focusing using the three distance measures method.
