Guide Print-DLGm (DLGm parameter adjustment)
If you press the SIZE button of the camera, select Guide
Print-DLGm, then execute printing, the guide image
(adjustment simulation) for changing the DLGm
parameters is printed out. The simulation is based on the
picture shown on the camera; you can actually see what
the result of the adjustment looks like.
The DARK parameter is changed
by +3 from the current value. The
dark part increases its darkness.
Picture of the current DARK,
LIGHT, and GAMMA parameter
values
The LIGHT parameter is changed
by –3 from the current value. The
bright part becomes darker.
The DARK parameter is changed
by –3 from the current value. The
dark part decreases its darkness,
and the picture looks like taken in a
bright place.
The values given under each picture are their DLGm
parameter values. For example, the top left picture in the
above figure has the following values: (DARK, LIGHT,
GAMMA) = (+3, 0, 0). To achieve that tone, set the D
parameter to +3.
To make further adjustments based on the top left
picture, set the D parameter to +3, then print the Guide
Print-DLGm again. This time, the center picture is based
on (DARK, LIGHT, GAMMA) = (+3, 0, 0), and the
surrounding pictures are the results of the changes with
reference to the center picture.

The center picture is based on the current values.
Around the center picture, six pictures of different color
adjustments are printed.

Tips on color adjustment
The Guide Print function gives a rough direction of
color adjustment. This function becomes more useful
when you consider the points explained below:
A guide image can be printed in black and white. As a
black and white picture in the UPX-C200 system is
made by overlaying the three color elements of cyan,
magenta, and yellow, the picture may not appear
completely monochrome, but may have some colors.
The balance of these three color elements can be
adjusted with the use of the monochrome guide print.
Complementary colors
A picture consists of data on three colors (R, G, and B).
Colors are converted by changing the balance of these
three colors.
When the R parameter is to be changed, the LCD shows
CYN-RED (cyan and red). Similarly, the LCD shows
MAG-GRN (magenta and green) for the G parameter
and YEL-BLU (yellow and blue) for the B parameter.
These combinations—cyan and red, magenta and green,
and yellow and blue—represent complementary colors.
For instance, increasing RED means decreasing CYN,
and decreasing RED means increasing CYN.
The LIGHT parameter is changed by
+3 from the current value. The bright
part becomes futher brighter.
The GAMMA parameter is changed
by +3 from the current value. The half
tone part becomes darker.

The GAMMA parameter is changed
by –3 from the current value. The half
tone part becomes brighter.
