STEREO BASE
Changing stereo base volume
| Although I will come to wish for avarice
to come out gradually and to take a
picture
of various photographic subjects if
a stereo
photograph is begun, a stereo base
afflicts
the head there. Since the realist who
can
generally receive is designed with
the stereo
base near man's eyes, although he has
turned
to the snap and the stereograph of
a close-range
view, correspond to that from which
a size
is remarkably different, and it does
not
become precocious, for example, in
the case
of small photographic subjects, such
as an
insect, what have a big stereo base,
such
as several mm and fireworks, is set
to 1m
or more. It seems that there is no
other
way but to make himself when it becomes
such
a camera. |
Macro photography
| When it is going to make a macro stereo camera, if surely becoming obstructive dares say in the size of a camera, it will be the diameter of a lens. When thinking simply, and two lenses are put in order and a stereo camera is made, it is impossible to make a stereo base below in the diameter. Then, if it says whether a stereo base can make the infinite camera near 0mm, there is no such thing. Although there are some methods, three actually made kinds are introduced. |

| If it is this which is the easiest method only by shifting horizontally like a photograph (refer to the "legible stereograph" to stop for shifting with a stock (under construction)), it is dependent on selection of a lens and a small thing is also O.K. (the world of a microscope is another). Although stereographs, such as scenery, are also possible if it shifts greatly, it cannot respond to what moves. It is because a time difference appears in the 1st photograph and the 2nd photograph. |
A surface mirror is used

weak point
|
| A photograph 1 is the principle which is seen from width and which divides an image into two with a one-way mirror. A penetration and reflection use 50% of mirror. Although it thinks that it turns out that a photograph 2 is seen, a stereo base can be changed by moving the camera of B horizontally. When it is this method, a photographic subject with motions, such as an insect which can start a stereo base from 0mm and is alive, is also O.K. Although it is visible to a wonderful system, there is a fault too. Since it is quite expensive even if it finds it, it is hard to come out of a hand, and that acquisition of a powerful half mirror (thing with which 50% of penetrations, 50% of reflection, and the color do not stick and with which coating is solid) is difficult, and in case it is photography, the quantity of 50% or more of light loses the biggest problem. And since an exposure multiple also starts for macro photography, a stroboscope is needed. (Refer to HighSpeed Flash) |

| Photograph 3 | Photograph 4 |
| Photographs 3 and 4 should notice a half mirror about a motion of the lens which it just saw from the front, and a next camera body. This gap becomes a stereo base. |
