Kodak EKTAGRAPHIC 270 - How to Avoid Image Cropping; Practicing the Program (before Recording It); Recording the Program on the Tape

How to Avoid Image Cropping
As you plan your slides, keep in mind that the more familiar you are with the
imaging requirements of the EKTAGRAPHIC AudioViewer/Projector (as with any
slide-display device having a built-in screen), the better you can prepare 2 x 2-inch
(135-format) slides that effectively communicate your message. Image legibility and
cropping are of prime importance with these communication devices.
Generally, you can use all of the transparency area of a 126-size slide. Horizontal
and vertical 135-size slides and 127-size super slides are cropped somewhat by these
display devices. About 3/64-inch (1.2 mm) of the long dimension (width) of a 135-size
slide is trimmed off each edge by the built-in screen. However, the narrow dimension
(height) of the slide will be visible.
Super slides lose about 1/4 inch (6.4 mm) of image height and width (3.2 mm at
each edge) when projected on the built-in screen of these machines. (It’s necessary
to crop some area from the larger formats so that images from the smaller formats
will not be too small for viewing.)
If you wish to fill the built-in screen of the AudioViewer/Projector completely,
one method is to use slides with a 30.8 mm square aperture. Slides with apertures of
this size are made by Kodak processing laboratories when KODACHROME
duplicates are ordered from superslides or from square transparencies made on
120- or 620-size film.
When projecting onto an external front screen (using the built-in front-projection
lens), the full picture area of all transparency formats (with the exception of 38 x 38
mm super slides that are vignetted when used with the short focal-length lens) will
be projected without image cropping.
We recommend that you shoot or select slides that have the same-size aperture
and same image orientation (all horizontal or all vertical formats).
All slides used with the AudioViewer/Projector are automatically registered
horizontally and vertically in both front- and rear-screen modes of projection.

Practicing the Program
(Before Recording It)
While reading the script, practice
pressing the slide-forward button (on
the AudioViewer/Projector or on the
optional KODAK AudioViewer/
Projector Remote Control 210/260 or
AudioViewer/ Projector Remote Con-
trol 410/460) to record the slide-
advance pulses (and to advance the
tray simultaneously). You may need
to press the slide-advance button a
second or so “ahead of schedule” so
that the images appear on the screen
exactly when they are supposed to.
(Slide-cycling time for the Audio-
Viewer/Projector is about the same as
for most KODAK EKTAGRAPHIC
III and EKTAGRAPHIC Slide Pro-
jectors—about 1 second.)
Recording the Program on the Tape
Although recording the audio track
and signal track of the program cas-
sette tape at one time (in the same
recording “pass” of the tape) is possi-
ble, it is not recommended. We recom-
mend that you record the program
cassette tape in the following order:
1. Record the audio with the micro-
phone.
2. Rewind the program tape to the
beginning. Disconnect the micro-
phone. Place the tray of slides on
the AudioViewer/Projector.
3. Record the slide-advance pulses
(and program-pause signals with
models 470 and 570AF) while lis-
tening to the audio, reading the
script, and pressing the slide-
advance button (and pause/restart
button) as required.
