---------------------------------------------------------------


* * GETTING STARTED * *

First of all, copy PROview II and it's associated files
to your hard drive. PROview II may be located in a
subdirectory of it's own and used anywhere on the system,
provided that it is included in your path statement and your
autoexec.bat file contains the following:

SET PROVIEW=[path where PROview II is located]
(be sure PROVIEW is capitalized)

**Special considerations:
Because PROview II makes huge demands on memory, for
optimum usage, make sure that you have extended/expanded
memory available on your system. By available, it is meant
that you have previously loaded a memory manager such as
HIMEM.SYS on your system. This makes available to the
running software all of the memory on your system. For large
images, this will surely be used as conventional memory
simply does not have enough available.

OPERATION:
PROview II is easy to operate and use. The Graphical
user interface provides all of the necessary controls to the
user in a style that anyone can learn easily. All you do is
point and shoot and away you go!




There are two ways in which to invoke PROview II. One
way is to simply type

'C7PROV' and press enter

at the system prompt and PROview will begin to operate.
This method causes PROview II to search your system for one
of the supported video cards. All detection is done
automatically and requires no intervention by the user. If
one of the supported video cards is not found on your system,
the default VGA 320 x 200 x 256 VGA mode is utilized. This
mode, however, is not supported in a lot of areas in PROview
II because of it's low resolution, and therefore full use of
PROview will not be attainable.
If your system has one of the supported video cards,
then PROview II will inform you of the type card found and
list out all of the available videomodes by providing
resolution buttons on the main menu screen. Each button may
be activated with the mouse pointer and a click of the left
mouse button. A videomode is 'active' when the button is
pushed 'in'.
The second method of starting PROview II is to cause
PROview II to disregard the supported video card search and
simply look for a video card that supports the VESA standard.

ALL RIGHTS RESERVED (BBS) (919) 556-0159




PROview II v3.13 Users Manual Page 6
---------------------------------------------------------------


If the VESA standard is not found, the PROview II will
default to the 320 x 200 x 256 VGA mode regardless of whether
or not your system has one of the supported video cards.
This method allows you the possibility of getting the
most out of PROview II in the event you do not have a
supported board and your video card DOES support VESA.
To FORCE VESA mode, start PROview II by entering the
following command at the DOS prompt:

C7PROV /V and press enter

If VESA is found on your system, it will be enabled and put
to use.

In summary ....
To start PROview II with an automatic video card search
C7PROV and press enter...
To start PROview II and force VESA detection
C7PROV /V and press enter




Once the intro screen has painted, the user is presented
with a menuing system that will take them on their way.
Because of the easiness in the software, we are sure that
most will find it very easy to use with little instruction.
PROview II is composed of basically a menu screen and
several types of viewing or editing screens. The menu screen
is where you control PROview II and make it do what you want
it to do. The menu is made up of various 'pushbuttons' that
enable a certain function or process. The process related to
a particular pushbutton is defined by its label displayed
right on the face of the button.
Activating a 'pushbutton' is done by simply pointing to
the button and pressing the LEFT mouse button. The button
will acknowledge this by being 'pushed in' showing that it is
active. Some of the buttons may also be activated by
pressing the RIGHT mouse button. This causes a secondary
action to occur that is related to that button, as in the
button 'SHOW'. By pointing the mouse pointer to the SHOW
pushbutton and pressing the LEFT button, you are telling
PROview II that you want a slide show of all of the images
that have been TAGGED in the file list window. If no files
have been tagged (indicated by a RED filename ) then PROview
II will inform you that you must tag the files first in order
to perform this function.
By pointing to the SHOW button and pressing the RIGHT
mouse button, you are telling PROview II to SHOW ALL of the
files in the current directory.

PROview II v3.13 Users Manual Page 7
---------------------------------------------------------------


The following describes the pushbuttons of the main menu
screen and what there functions are:

File Filter Buttons.....
These buttons are located across the top of the file
list window and serve to filter 'IN' the different
image file formats. Each button if 'active' will
cause PROview II to include that image type in the
file list window. If the button is 'inactive'
(pushed out), then that respect file type will NOT
be included in the file list window.

Load.....
The 'load' button will load the currently selected
file (hi-lighted) in the file list window into
memory. This button will not cause the image to be
displayed when activated.

Save.....
The 'Save' button will take the current active image
and save it to any of the other type of supported
image file formats currently supported (ie. GIF,
CX,TIFF, or TGA). To choose the type of format to
save the image as, simply include the formats
extension in the filename. For instance, to save
the current image as a GIF file, enter the desired
filename, such as 'image1.GIF', and PROview II will
know that you want to save the image as a GIF
formatted image and proceed to do so. If you are
save an image as a TGA, PROview II will first
convert the image to a 24-bit RGB image and offer
you a selection of the type of compression to use,
if any.

View......
The 'View' button causes the current image to be
viewed in the current videomode as selected by the
video resolution buttons. To return to the menu
screen, simply press the LEFT mouse button while
viewing. If you are viewing an image whose
dimensions are LARGER than the screen dimensions of
the current resolution button selected, you may
still view the entire image by scrolling the image
using the following keys:
LEFT arrow
RIGHT arrow
DOWN arrow
UP arrow
HOME
END
Using these keys will allow you to completely
navigate around the image very quickly.

---------------------------------------------------------------


Print.....
One of PROview II great qualities is the ability to
produce high quality hard copy to a laser jet
printer. Several options are available that allow
the user to customize the final output. Selecting
the 'Print' button causes the printer setup menu to
appear. The menu contains the following structure:

Width...
Height... Both fields represent the
size of the printed image in
inches. To maintain the correct
aspect ratio, the height
automatically tracks the width.
To alter the aspect ratio, adjust
the WIDTH to the desired dimension
then follow with an adjustment to
the height dimension.
To change a dimension in
either of the fields, first make
that field active by pointing to
the desired field and clicking the
LEFT mouse button. The RED dot to
the right of the field will change
to green, indicating it is active.
By pressing either of the 'up' or
'dn' arrow buttons the dimension
will change accordingly.
DPI.....
PROview II allows the user to select
any of the 4 printer resolutions of
75, 100, 150 or 300 DPI. Simply
point to the desired setting and
click the mouse button to make it
active.

BORDER....
You may optionally include a border
around the printed image or none at
all by making the appropriate
selection of None, Fine, Medium, or
Thick.

There are two methods of printing, by DITHER or Error
Diffusion. The dither technique has 6 choices, each of which
will produce a different looking hardcopy. Error diffusion
is a technique where 256 shades of gray are simulated in the
print out. This method generally produces the best looking
hard copy, but does take the longest time to complete.
To enhance an image for printing, select the Brighten
image for Printing selection. This helps to bring out more
detail in an otherwise 'flat' image. The default for this
setting is ON.

---------------------------------------------------------------


DEL....
The 'Del' button is used when you desire to get rid
of any files that are currently shown in the file
list window. Selecting this button will delete, at
user permission, the current hi-lighted filename in
the list. If you wish to delete a filename that is
not hi-lighted, simply point to the filename in the
list and press the RIGHT mouse button. The filename
will be shown in RED to indicate that it has been
selected.

QUIT....
The 'Quit' button does exactly that! PROview II is
terminated and the DOS prompt is returned. Be
careful, in that any image currently in memory will
be lost when this is selected. Use the SAVE button
to save the image in memory to a disk file first if
you are concerned about losing it.

VIDEO RESOLUTION.....
To the right of the screen is a series of buttons
that are labeled with their respective screen
resolutions if activated. These buttons will vary
from video board type, and may be different from one
system to another. If the button is selected, then
THAT video resolution will be used when in Edit
Mode, doing thumbnails, or viewing the current
image.

SIZE To FIT....
The 'Size to fit' button will cause any image being
displayed in either the VIEW or SHOW modes to fit
the current video resolution selected, whether it be
larger or smaller that the actual screen dimensions.
For instance, to view a 1024 x 768 x 256 image in
it's entirety on a screen resolution of 320 x 200
x256, then select this function and the image will
be reduced down to fit the screen. This also works
in reverse, of course.

Build Thumbnail....
This function allows the user to collect together
many image files, in reductions of 2 to 9, color or
black and white, to one screen area for collective
viewing. You may also, optionally save the new
image thumbnail to a GIF formatted file for latter
viewing. Images used in the thumbnail begin at the
first file or first TAGGED file in the file list
window. The first file loaded also governs the
color matching of the remaining images to the
screen, meaning if the first image is a black &
white, then all of the other images will turn out
black & white whether they are color or not.

---------------------------------------------------------------


EDIT MODE.....
Activating this mode allows you to make alterations
to or create special effects to the current image in
memory. Partial image captures may be performed, as
well as resizing of the entire image. In addition,
the user may make numerous alterations, such as
brightening, posterizing, sharpening, blurring, etc.
in an easy to use Pull down menu system all driven
by mouse. This mode is supported for all SVGA modes
only. 320 x 200 x 256 is not supported.
The following list and briefly describes the
available functions:
G-sharpen ....
This performs a 'gentle' sharpening
of the entire image causing minor
details to be increased.
H-sharpen ....
This preforms a 'Heavy' sharpening
of the entire image and sharply
increases detail and noise in the
image.
Blur ...
Performs a 'smoothing' of the pixel
in the image, causing a blurred
effect.
T-Blur ...
Threshold blurring only blurs edges
that are above a value as determined
by the user at time of selection.
The higher the number the MORE
blurring occurs.
H-Linearization ...
This function reassigns brightness
levels of the image so that the
integral of the resulting histogram
increases linearly with brightness
level. This produces best results
on dark images where detail in the
darker areas of the image are
brought out.
H-Brightening ...
This function brightens an image by
reassigning brightness levels so
that the integral of the resulting
histogram increases quadratically
with brightness levels. This
generally improves contrast, but
detail may be lost.
Brighten ...
This function allows you to raise
or lower the value of each pixel in
the image by an amount entered.

ALL RIGHTS RESERVED (BBS) (919) 556-0159




PROview II v3.13 Users Manual Page 11
---------------------------------------------------------------


H-Equalization ...
This function reassigns brightness
levels of the image so that every
brightness level has an equivalent
number of pixels resulting in a flat
histogram. This works best on
images with poor contrast. The
process may take a little while to
finish. To let the user know that
the system has not hung up, a beep
will occur every so often.
Divide ....
This function will allow you to
divide the image by a user enter
value. This will darken the image
and also reduce its color
resolution.
Multiply ...
This function increases each pixel
in the image by multiplying the
level with the value entered by the
user.
Posturizing ...
This function creates a special
effect by reducing the level of
color resolution in the image.
Pixelizing ...
This will assign brightness levels
in a local region of user defined
size, to the average causing a
mosaic appearance in the image.
Contrast ...
This function increases the contrast
the current image by an amount
entered by the user.

EFFECTS ....
In Metal ...
In Concrete ...
In Granite ...
In Cast Iron ..
Charcoal rendering ...
Oil Painting
These functions produce an embossed or
otherwise different look in the image with
effects similar to their descriptions.
Different images cause different results.
Experiment and have fun!
TRANSFORMING ...
Flip ...
Flip causes the image to be turned
upside down. Flipping an already
flipped image, of coarse, brings it
back to it's original form.

PROview II v3.13 Users Manual Page 12
---------------------------------------------------------------


Mirror ...
This function simply swaps the left
side of the image for the right.
Resize ...
This function is powerful in that it
will allow you to easily resize the
image to any size up to the limits
of the current videomode selected.
A box will from that moves with the
movement of the mouse. Create a box
of the desired NEW size you want and
press the LEFT mouse button. The
image will be resize to the
dimensions of the formed box.
Convolve ...
This function will allow the user to
convolve the active image with a
user defined matrix for special
custom effects.
CAPTURE ...
To capture any portion of the
viewable image, use this function.
Position the mouse pointer to one
corner of the area that you want to
capture and press the LEFT mouse
button. Form a box around the area
to capture and press the LEFT button
again. The image is captured and
redisplayed. If you 'accept' the
captured image data, then it will
become the current image and the
rest is discarded.
3D-IMG ...
To create three dimensional image
slides from LEFT-EYE and RIGHT-EYE
frame image files. Two slides type
are available, Red/Green or Stereo.
Quit ...
This function returns you to the
main menu screen without losing the
current image or any of it's
changes.

SCROLLING the image ....
You may easily move the current image if it is larger
that the viewing screen, by utilizing the scroll bar buttons
located at the left and bottom above the palette window. The
letters within each button indicate it's function. For
instance 'U' means move the image closer to it's origin and
'D' means move the image closer to it's ending coordinate.
Pressing the LEFT button in the scroll button will cause a
very slow and gradual movement and pressing the RIGHT button
will advance or retreat the image at great speed. Holding
the button down will repeat the precess over and over until

an image boundary is reached. To quickly get to the
beginning or end of an image simply press either the 'E'nd
and/or 'H'ome scroll buttons.

PALETTE viewing ...
To give a glimpse of the color scheme used in a image,
the palette is displayed at the bottom. A future version
will allow manipulation of the colors in the palette.


* * Video Digitizing * *

PROview II has built in support for the popular frame
grabber produced by Digital Vision, ie. ComputerEyes Pro.
With this frame grabbing capability, you can now grab video
images and without exiting the software, go directly to
viewing, and/ editing of the captured image. Version 2.00 is
released with added support for the ComputerEyes frame
grabber board which gives you control of the board in a very
similar manner as you are accustomed to in the software that
accompanies the grabber board itself.
To utilize the ComputerEyes frame grabbing capability,
be sure that your hardware has been properly setup and is
functioning as outlined in the Digital Vision user's manual.
First, select the 'Eyes Setup' button, and verify that the
software will operate as you desire. Please note that
PROview II only supports the 320 x 200 x 256 VGA mode when
running under VESA compatibility. After checking and making
the necessary settings for the grabber board, exit the setup
routine, by pressing the 'Quit/Save' button. The present
configuration will be saved to a config file in the current
directory for later use during a frame grabbing session. If
the config file cannot be found, the PROview II will use it's
system defaults.

---------------------------------------------------------------


PREVIEW Mode ....
To enter the 'Preview Mode' and grab a video image,
select the 'ComputerEyes Pro" button. A live video image
displayed in real time will be displayed. You may make the
necessary adjustments in much the same way that you have been
accustomed to. When you are satisfied with your settings,
press the 'enter' key to grab the image. In a few seconds,
the captured image will gradually be painted to the screen as
the video data is digitized. Upon completion, a short
'bleep' will be heard, signaling to you that the image
capture has been completed. To 'Accept' the captured image,
simply press...
'Enter'

and the main menu screen will return. If you wish to capture
the video image 'again', simply press ...

'ESC'

and you will be returned to the preview mode where additional
adjustments may be made and a new capture re-initiated.

Once the image has been captured, you may utilize any of
the PROview II functions to change or alter the image just as
you can with any image that has been loaded in from disk.
Note that any image previously loaded in PROview II prior to
capturing any image, will be lost and overwritten by the
captured image.

---------------------------------------------------------------


CONVOLUTION....
A new menu item for the 'TRANSFORM' edit menu pull down
called 'CONVOLVE' has been added. Convolving an image with a
matrix can create many useful and spectacular results and is
used quite frequently in current image processing techniques
today. Selecting 'Convolve' will cause a scroll window and
matrix select menu to appear. The scroll window will contain
a portion of the current active image for preview purposes in
testing the current matrix. The user may scroll the image
with the window to any location on the current active image
by use of the vertical and horizontal scroll buttons. The
matrix menu contains a 3X3 matrix containing 9 elements and a
divisor all of which may be user set. In addition, user
buttons for 'Preview', 'Apply', 'Open', 'Save', and 'Quit'
are provided for control and application of the matrix upon
the current active image. Beneath the matrix elements are
two buttons marked with '+' and '-' for use in changing the
contents of the selected matrix element.
Five standard matrix filters are supplied with the
software. Additional custom matrix filters may also be
created by selectively changing the desired element in the
matrix using the '+' & '-' pushbuttons and selecting 'SAVE'.
To test the current matrix on the image, click on the
'Preview' pushbutton and the convolution is applied to the
image in the scroll window. To restore the image to it's
original state, click on one of the scroll buttons
momentarily. To 'Apply' the current matrix to a particular
area of the current image, first scroll the image so it is
viewable in the scroll window, then click the 'Preview'
pushbutton. To accept the current matrix and 'Apply' it to
the entire image, click on the 'Apply' pushbutton. The
current matrix will be applied to the image and you will be
returned to the editing screen where you may either 'Accept'
or 'Undo' the image.
Matrix elements may be changed by clicking 'on' the
desired element in the matrix. A selected matrix element
will appear 'white' in color. To increase the value of the
element, click on the pushbutton marked '+'. To 'decrease'
the value of the value in the element, click on the
pushbutton marked '-'. All elements in the matrix may be
varied from -128 to 128.
Custom matrix' may be saved to disk by selecting the
'Save' push button. You will be prompted to provide a name
for the file. All matrix filter files end in the extension
'MTX' and will automatically be added to the end of the name
you enter, so leave off the extension in the filename.
Entering a 'blank' at the prompt will terminate the save
function.

clicking on either of the scroll buttons in the box.
Selecting 'YES' will load the selected matrix filter,
selecting 'NO' will abort the process and return you to the
matrix menu.
Example: To HEAVILY BLUR an image, one could do this by
choosing a pixel in the image and summing all adjacent pixels
in it's neighborhood and dividing the result by the number of
pixel samples (9). The result would then replace the value of
the original pixel sampled ( the center pixel). Repeating
this process over the entire image would result in a blurred
image.

The following matrix will produce this same effect......
1 1 1
1 1 1
1 1 1
9 (divisor)

....... and quite quickly!

THREE-DIMENSIONAL IMAGE SLIDES ...

New in v3.00 is the ability to produce true 3D images in
full 256 color. The result is fantastic and truly realistic!
What is needed is the proper video digitizing equipment and
either a stereo viewer or a pair of the popular RED/BLUE
stereo viewer glasses. PROview II will produce images
tailored for viewing in either of these methods and the one
you choose will probably depend on what viewer you have
available.

Stereoscopic ...

First, to view the 'stereo' 3D images you will need what
is called a 'stereoscope'. A stereoscope is an instrument
(don't be scared by this word as you can easily construct one
yourself) that contains a pair of lens mounted in a frame
constructed of rigid material. The lens (approx. 2-1/4"
dia.) are mounted on a flat over pre-cut holes of diameter
slightly smaller that the lens itself, spaced at
approximately 2-3/4" to 3" from center of each other so as to
form what looks like a rather strange pair of glasses that
you can look thru. The lens should be a plano convex type
with the 'convex'(curved) side facing away from the viewer's
eyes when used. The one constructed in our tests, used lens
obtained from an inexpensive magnifier found in a popular
drug store. The lens were made of plastic and were placed
back to back (plano-side to plano-side) to form a 'condenser
lens' for the purpose of magnifying. Separating the two lens
provided the necessary lens for the stereoscope we
constructed.
Note: Some magnifiers contain a single condenser lens and
these will not work.
The center thickness of the lens should be approximately
1/16". This will allow the user to view an image 9" or so
from the viewing plate. To further along in the description
of the stereoscope, there should be a rigid divider 9" long
and the same width as the lens plate, placed vertically
between the two lens mounted on the lens plate, opposite the
side the user would look thru. This can be permanently
mounted to the lens plate. The purpose of this plate is to
restrict the vision of each eye so that each eye will see
ONLY what is directly in front of it and not any of the image
that the other eye is seeing. The stereo slide is placed at
the end of the 9" divider with the divider resting in the
center of the left and right image. When the image is viewed
thru the lens, the image will appear in three dimension.
With this sort of instrument, the user's eyes see two
different images and the mind mixes them together to form
one, or a composition of both which tricks the user in to
seeing an image with 3 dimensions, that is, an image that has
'depth', 'width', and 'height'.

PROview II will take two previously captured images of
the same size, and resize them to appropriate dimensions in
the current screen resolution, match the image palettes to
form one, and place them side by side to from a stereo slide
which may be viewed in 3 dimension with a suitable
stereoscope. The slide may also be printed (adjust to 6"
width for optimum) and viewed in three dimension on paper
with the same type of viewer. This process is effective for
both black & white and color images.

Red/Green stereo ...

Another method of producing a stereo image is thru the
use of double imaging and the use of RED & GREEN filters.
By taking two captured images, at slightly different
perspectives, passing the left perspective image thru a RED
filter, leaving only varying degrees of red, and passing the
right perspective image thru a GREEN filter, and merging the
two images into one image of both colors we can view the
complete original image in full 3 dimension with the use of
RED/BLUE stereo glasses. The RED lens should cover the LEFT
eye to get the proper depth perception. The glasses perform
a similar function as the stereoscope, in that the RED filter
allows the left eye to see only the left image perspective
(RED) and the BLUE filter allows the green image perspective
to be seen. Your mind puts the images back together with the
illusion of three dimension and color because RED and GREEN
are opposite each other in the color spectrum.


CAPTURING LEFT & RIGHT FRAME IMAGES FOR THREE DIMENSION....

In order to utilize the 3D capabilities of PROview II
and begin producing your own stereoscopic slides, you will
first need to produce two images that contain a different
view perspective. The best way to do this is to have
suitable video capture equipment, such as the ComputerEyes
PRO frame grabber board, and a video input source. Our
examples were produced using an RCA camcorder aimed at the
subject from a tri-pod mounting. You may also use the Cannon
rc-250 xapshot camera. It works well also, but with less
video resolution. The key to generating a three dimensional
image is to try and capture what EACH human eye would see.
What the lens of the camera sees in one shot is what one
human eye would see at the same instant. By positioning the
camera in front of an object and digitizing that video scene,
we have what can be called a ONE EYE perspective. If we move
the camera from it's current position to the right by about
1/4" and then digitize the same object again we now have yet
another ONE EYE perspective, but this one is different from
the first one in that it was captured at a different
perspective. This difference can be called LEFT -RIGHT
perspective, which is what each eye would see independently
when viewing the same object. The scenes in each image look

almost identical, but they are truly different and when
combined together, will form a three dimensional rendering
of the original scene. This is the process you will need to
carry out to produce each 3d image in PROview II.

e.g.: 1> Aim the camera at the object and capture it.
Refer to this image as the LEFT-EYE frame and
save it to disk with a name that identifies
what it is, such as 'L-scene.gif'.
2> Shift the position of the camera to the RIGHT
about 1/4" and capture this image. Refer to
this image as the RIGHT-EYE frame and save it
to disk with a filename that identifies what
it is, such as 'R-scene.gif'.

Producing the three dimensional slide....

Once you have created both your LEFT and RIGHT frame
images and saved them to disk as 'GIF' files, enter into
'Edit Mode' in PROview II and select the menu item '3D-img'.
A dropdown menu will appear containing 'RED/GREEN' and
'STEREO'. After selecting the type of slide you want to
produce, a file list box will appear containing a list of all
available 'GIF' image files found in the current directory.
A prompt will inform you to 'Select the LEFT-EYE frame->'
where you will find the LEFT-EYE frame you captured, such as
'L-scene.gif'. Once the left image has been selected,
PROview II will prompt you to select the RIGHT-EYE frame.
After both images have been selected, the message 'Working'
will appear on the screen and in a few moments your finished
slide will be presented to the screen.
If you selected RED/GREEN, PROview II will allow you to
enter in custom FILTER values for the generation of the
slide. At this time, you will notice a prompt asking for a
new value to use for the RED filter. The default value for
this color is 100 (maximum). You may enter any value from 1
to 100 creating varying results in the final slide
generation. By simply pressing , PROview II will
assign the value to the default. The same procedure will be
repeated fro each of the colores (RED, GREEN and BLUE).
Upon completion, this resultant slide becomes the 'active
image' and you may continue with other image processing, etc.
as you would normally. To view the slide, simply display it
on the monitor and with the appropriate stereoscopic viewer,
sit back and enjoy the a whole new way of viewing computer
graphic images on your system's monitor.

HINTS:
1> When producing the LEFT & RIGHT image frames, the more
separation each image has from the other, the MORE 3
dimensional effect your finished slide will contain,
however, producing too much separation, will cause a
'double-image' effect when the slide is viewed, thus a
loss of the three dimensional effect all together. If

this occurs, reshoot the images using less distance
between each scene.
2> Capture images that are not moving, as movement between
frames can cause distortion in slides.
3> STEREO slides can be printed to a laser printer and still
retain their ability to be viewed in three dimension.
Optimum slide width should be set to about 6" in order to
view the image in 3D with a stereoscope similar to the one
mentioned in this manual. RED/GREEN slides, however, will
loose ALL of their three dimensional characteristics when
printed because of the lose of color.
4> When viewing the RED/GREEN slide, always place the RED
lens of your viewing glasses over the LEFT eye and the
BLUE lens over the RIGHT eye. Failure to do this will
result in a loss of the 3D effect and a very 'bad' looking
image!
5> Viewing a RED/GREEN slide with a pair of glasses
a RED and GREEN lens will cause your RED/GREEN slide to be
seen in BLACK & WHITE.
6> While viewing the RED/GREEN slide, adjusting the monitors
brightness and contrast controls will sometimes improve
the viewing quality.

7> Anybody for a REAL 3D game? hmmmmm...
