Taking Pictures
b Viewing 3D pictures by the parallel method and cross
method
As our eyes are positioned about 6 – 7 cm apart, there is a very
slight deviation between what we see with our right eye and
what we see with our left eye.The difference is processed by
our brain to produce a three-dimensional image.This principle is
applied to taking and viewing 3D pictures.
3D pictures can be viewed by the parallel method where the left
and right lines of vision are virtually parallel, as when looking at
a distant scene, or the cross method where the left and right
lines of vision are crossed, as when you cross your eyes. A cer-
tain amount of practice may be necessary to view 3D pictures
without using the viewer.
b How to Assemble the 3D Image Viewer
Assemble the 3D image viewer supplied with the camera as
shown below.
m
Press the OK button.
The screen for taking the first image appears in the left half
of the LCD monitor.
,
Take the first image.
Hold the camera so that the subject
is in the middle of the left half of the
screen and press the shutter release
button.The image is displayed in the
left half of the LCD monitor.The right
half of the screen is for taking the
second image.
.
Move the camera to the right with-
out changing your stance.
⁄0
Take the second image.
Make sure that the subject is in the
middle of the right half of the screen
and press the shutter release button.
To cancel the 3D image mode change to another Capture
mode.
A clear three-dimensional effect will not be achieved if the two
images are taken in widely different positions (heights) or are
not straight.When taking a person, you are recommended to
ask your model to stay as still as possible and to take the
second picture as quickly as you can. It is easier to take the
pictures if you use a tripod or appropriate base.
As a guide, the camera should be moved about 1/40 of the
distance between the camera and the subject. For example, if
the subject is 3m away, the distance the camera should be
moved will be 3m÷40=7.5cm.
However, as the way people see three-dimensional images
differs from person to person, there is no need to be too con-
cerned. Refer to the table below for a simple guide to how far
to move the camera.
