Guide Print-DLGm (adjusting DLGm parameters)
Selecting the Guide Print-DLGm layout before printing
enables a color guide to be printed for the DLGm
parameters. Since the picture used for printing is the
picture being played back on the camera, you can
actually adjust the picture quality while looking at the
picture. The picture in the center is printed using the current
color tone adjustment values. Six playback images of
differing color are printed around this picture.
The values below each of the pictures are for the D, L,
and Gm parameters. If, for example, you want to use the
tone on the top left in the figure above, set the D
parameter to +3 because (DARK, LIGHT, GAMMA) =
(+3, 0, 0).
If you want to adjust (DARK, LIGHT, GAMMA) = (+3,
0, 0) further, set the D parameter to +3, and then print
another Guide Print-DLGm. This will give you a
simulation picture for each parameter variation with
(DARK, LIGHT, GAMMA) = (+3, 0, 0) in the center.
Advice on adjusting color tones
The guide print function gives you a rough guide as to
how to adjust the color tone. However, if you understand
the following, you can use this function to its full
potential.
The guide print can also be used for black & white
prints. Black & white pictures printed with this system
are printed by overlaying the three colors cyan, magenta,
and yellow to express gray. Therefore, a perfectly
achromatic picture may not be obtained and colors may
sometimes be visible. A black & white guide print can
be used to adjust the balance of these three colors.
Complementary colors
Pictures are made up of the data of three colors (R data,
G data, and B data). The color tone adjustment function
can be used to change the balance of these three colors.
When the R parameter is changed, the CYN-RED (cyan
and red) indication appears on the LCD. Similarly, the
MAG-GRN (magenta and green) indication appear on
the LCD when the G parameter is changed, and the
YEL-BLU (yellow and blue) indication appear on the
LCD when the B parameter is changed.
The complementary colors cyan and red, magenta and
green, and yellow and blue are related. For example,
increasing red makes cyan lighter and decreasing red
makes cyan deeper.
This is a picture showing the DARK
parameter increased by 3 from the
current state. With focus on the deep
parts, this has become a picture with
more depth than the current one.
This is a picture showing the current
state of the DARK, LIGHT, and
GAMMA parameters.
This is a picture showing the DARK
parameter decreased by 3 from the
current state. The deep parts
become lighter as if the picture was
taken in a bright place.
The current state of each of the
RED, GREEN, and BLUE
parameters is displayed for
reference.
This is a picture showing the LIGHT
parameter increased by 3 from the
current state.
The light parts become lighter than
in the current picture.
This is a picture showing the
GAMMA parameter decreased by 3
from the current state.
The halftones become slightly lighter
than in the current picture.
This is a picture showing the LIGHT
parameter decreased by 3 from the
current state. The light parts
become slightly darker than in the
current picture.
This is a picture showing the
GAMMA parameter increased by 3
from the current state. The halftones
become slightly darker than in the
current picture.
