5.1 Choosing a Developer File
The MegaVision Camera Back System is designed to allow a quick and easy
transition to digital imaging for the professional photographer.
This manual explains how to start and work with PhotoShoot and the cam-
era back. It is not a replacement of the MegaVisions User Guide. It is just
a summary explanation of the most important features in the software
and a useful tool in learning.
INSTALL THE HARDWARE

3. LAUNCH SOFTWARE
Set camera to T3 (Setup menu > Camera > T3 Camera)
4. SET UP THE RANGE
The default colors may be changed for commercial photography require-
ments. If your version of software has the Commercial settings in the
installer, do the following:
A: Select Setup > Range.
B: Click on LOAD. Use the search box to find your PhotoShoot 3.1 folder.
Look for a file named "Commercial.range". Select by double-clicking. If
your version of software does not have the Commercial file, you may make
your own, or use the following settings as a starting point:
1-0% = Red (255,0,0) -- WARNING will not print
5-2% = Yellow (255,255,0) -- WARNING may not print
10-6% = Light Green (0,245,0) -- Target white value

functions such as Retouch, Crop, Tone Control, Neutral Balance, Sharpen
and Convert (described below) are made to the image data held in memory
and not to an image file held on the hard drive. You must save the changes
to disk to update the changes to your file.
Cropping boxes can be created, placed, moved, stretched or compressed.
Cropping can only be performed on a captured image or opened image,
Saved crop boxes can be applied to subsequesnt images if the "save crop/

This feature is used to compensate for slight imbalances in color tempera-
ture of the lighting and also to correct for some effects of gross lens flare.
With an RGB image and the Neutral Balance Function window open, neu-
tral reflectances in the image can be selected and rendered neutral.
The neutral function is implemented by selecting a number of points in
the image that need to be neutral. The software then performs an averag-
ing of the RGB readings at those points and installs the average as the
value to be applied. The average value may also be edited to obtain exact
The established values can be saved in a MegaVision "Neutral" file, and
recalled again for later use. A neutral file defined in this manner can also
be used when applying a Batch of corrections and adjustments to a folder
of image files.
This function is used to modify an RGB image. After clicking on the Tone
button a graph appears in the Multipurpose window above a row of five
check boxes labeled Shadow, 3/4, Mid, 1/4 and Highlight. The Tone curves
shape may be altered extensively (even inverted) by the use of the control
buttons and boxes below the graph or by using the mouse to click on the
curve and change its shape by dragging. The large and small + and - but-
tons permit coarse or fine movement of steps of 10 or 1 respectively. When
a satisfactory Tone curve is generated, click Apply to to modify the dis-
played image. Clicking the Save button will allow the data to be saved in a
MegaVision "Tone" file for subsequent application to individual images or
in batch processing. A selection tool has been added to allow the user to
define an area in which the tone funcitons will only be applied to.
MegaSharp sharpening is used to create visual effects in the image so that
the observer feels that the reproduction has a realistic appearance. Sharp-
ening should be applied at the reproduction's target size and resolution.
We strongly recommend viewing the area of interest at 1:1 using the Zoom
key-combinations. This allows you to more accurately see the effect of
Sharpening. The appropriate starting points for a typical Sharpening setup
Blur Treshold 0
Sharpening Treshold 3-20
Kernel Size 2-10
You can make and save your own settings. There are 10 different settings
available. We suggest you name any custom sharpening by entering its
values (for example: 0/4/200/3) as its name. After entering the
MegaSharp values, highlight the name of the file at the top of the dialog,
enter the sharpen name and choose OK.
MegaVision can provide a CMYK conversion file or files that are based on
data supplied by the user. The custom CMYK conversion curve information
can be obtained by contacting CDS or Customer Support at MegaVision or
by contacting your local sales representative. Calibrate RGB can be ap-
plied to your image if you wish, the program is used to provide the most
accurate color rendition possible. check the selection box at the top left
to activate. Settings should be discussed with your technical representa-
tive or refer to the omplete manual for further informaiton.
In this procedure, functions like Crop, Neutral, Tone, Sharpen and Convert
can be selected to make a programmed script of functions to be applied to
a picture. Thereafter, clicking just one button will automatically apply the
chosen functions to selected images - resident in a folder or selected in
the PhotoShoot RAM buffer.

Check the box labeled Meter. The Multipurpose Window displays a histo-
gram plot of the luminance values of all the pixels in the scene versus fre-
quency of occurrence. After capture with the Meter checked, the image will
be displayed with Color Coded Light Metering, which displays important
exposure information relating to highlight, shadow, and any other user-
defined print parameter.
Note that a thin green outline box with small solid squares at the centers
of each side and the four corners is seen when the Meter is activated. This

4.2 Setup Menu
Setup >Camera model
The PhotoShoot software allows capture from the triple-shot T3 digi-
tal camera back, and the single-shot S2 and S3 digital camera backs.
The appropriate camera is selected here.
Two rulings of overlay grids are available to verify vertical and hori-
zontal relationships within the image area. Coarse = 64 pixels be-
tween gridlines; Fine = 32 pixels.
The Black correction files are managed here; captured, saved to disk
and loaded. Setup>Black>Capture generates a new Black correct
file; Setup>Black>Previous opens a File dialog box so that a previ-
ously saved Black correction file may be loaded. The Enable option
allows the dark coorection function to be enabled/disabled.

OK allows the continuation of the Setup Balance process; Cancel
Setup >Balance Lighting
The last of the three balance entries on the drop-down menu will
be implemented in a future Software revision. Its purpose is to pro-
vide a generic Setup Balance for the various light sources listed in
case the user fails to create a Setup Balance file during the session
and no white reference area is available in the scene.
Setup >Preferences - Camera
For PhotoShoot to operate, a valid Parameter file must be assigned
in Preferences- Camera. If the software has been installed success-
fully from the CD provided with the camera back, these files will be
correctly assigned from files in folder Data Files in the PhotoShoot
The Parameter file contains camera back specific data and the names
of gain and black correct files. It also holds initial values for white
balance. If a new black correct file is created or new balance values
are acquired, PhotoShoot writes these values to the Parameter file
so that they are available for subsequent captures.
The Parameter file name is derived from the camera-back serial num-
ber. Verify that these match, otherwise correct captures will not be

4.4 View Menu
View > Red/Green/Blue/Luminance Separation,Original
The Red (Command/1), Green (Command/2) and Blue (Command/
3) separations are the channel components of the RGB image. The
Luminance value displayed (below the R,G and B) is information
about the density of a reflectance without regard to its color (very
much like the traditional spotmeter whose readings of color
reflectances contain only exposure information). These channels
may be printed if required. The Original image (Command/0) is the
combined RGB displayed simultaneously.
4.5 Image Menu
This selection converts a color RGB image to grayscale. This image
corresponds closely to a B&W image captured on panchromatic film.
When a grayscale image is currently loaded, this selection produces
an RGB image with all channels (R,G,B) the same, producing an
image not very different in appearance from the original grayscale
image. The separations may be manipulated to add color to the im-
age. This selection is typically used to tint grayscale images when
printing to a color output device.
This function produces an RGB image is much the same fashion as
the RGB Color, except that the separations contain the range colors
currently selected in Setup>Range.

5.1 CHOOSING DEVELOPER FILES
New Naming Structure
MegaVision has changed the S2 and S3 Developer names. While the devel-
oper names have changed, the developers are the same. Developer file
names have been changed to reflect a standard "filmspeak" nomencla-
ture (which should be understandable to all photographers) including a
numbered appendage that will reflect the density range (contrast) and
deviation from the CCD's optimum exposure index (a software ISO change).
Naming includes a concatenation of the names the individual atributes
making up a developer. All developer files have a MV prefix. An example of
a Developer name is: MVN 2505.
Color renderings will fall into two broad categories; MVN and MVS. MVN
will denote neutral, color correct renderings throughout the camera's
entire color gamut. MVS denotes a skintone rendering; skintones will ren-
der warmer in a fashion consistent with the portrait emulsions we often
choose for pleasing fleshtones. Additional lower case letters have been
added to indicate specific color adjustments for each color category (for
instance MVNs indicates a neutral rendering with extra saturation).
MVN This is the neutral rendering (the old Slik). Following the Eastman
nomenclature of EPN (Eastman Professional, Neutral), MVN stands for
MegaVision Neutral; this is our most color correct, neutral rendering.
Additional saturation will add the lower case "s" becoming MVNs (MVNs+
for extra extra saturation). For those shooters with both cameras, S2 or
S3 should precede the Developer name to denote the intended camera
MVS This is the MV Skin rendering (now known as Ivory). Following the
Eastman nomenclature of VPS (Vericolor Professional, Short), MVS stands
for MegaVision Skin; this is our default skintone rendering. Additional
warming will add the "w" to indicate additional warming becoming MVSw.
Each Developer name includes the density range (contrast) where the larger
the number, the more tones the rendering contains (softer contrast).
Lower numbers have fewer tones indicating greater contrast.
Tone Tune (TT) Files
Due to the usability of the S3 remaps in the S2 camera back , the same TT
files will be used for both cameras (except for old renderings we need to
keep for those shooters who need to continue to shoot old renderings).
Hence, TT 2505 will work for S2 and S3, MVS or MVN.
Color Tune (CT) Files
Color Tune files will reflect the familial naming structure of Skin and Slik,
becoming CT S2 MVS or CT S3 MVN.
Files and Folders
Currently , the PhotoShoot installer places the camera Parameter file in a
folder called "Data Files" in the folder containing the PhotoShoot applica-
tion. The installer creates the following folders: "Developers", "Color Tune"
and "Tone Tune", in the "Data Files" folder.
A parameter file describes your specific camera back. Tone Tune and Color
Tune files make up the building blocks of a Developer file. Completed Devel-
oper Files are saved to the "Developers" folder for selection and subsequent
use. You can choose any of the pre-made Developer files if you don't want to
make your own custom files. If you do want to make your own custom files,
they can be made using the "Create" button in the "Camera" dialog box.
