Fig. 7.11: Screen “Photo Channel – Red”.
Use the “Settings” button to define how the
B&W image is generated. You can either select
to use the luminance channel of the picture or
make your own channel mix of Red, Green and
Blue channels. If the total sum (in percentage)
of Red, Green and Blue is not 100%, you can
use softkey 3 (100 %) to normalize this.
7.4.4 Show Histogram
A levels view (or histogram) illustrates how
pixels in an image are distributed by showing
the number of pixels at each color intensity
level. Press softkeys 1, 2, 3 or 4 for the full
color image and for Red, Green, Blue channels
individually. Softkey 5 shows the luminance
channel.

Again by moving the joystick left or right you
can view the channels of the previous or next
pictures.
You can either press the joystick (enter) or the
‘Back” button to leave the “Levels” mode and
go back to standard picture viewing
7.4.5 Rotate Pictures
Sometimes the cameras do not include the
information of the orientation in their EXIF
data. If you want to turn a photo from
“Landscape” to “Portrait” or the other way
round, press softkey 5, “More” in the picture
viewing mode.
Then the softkeys get another function as
shown in fig. 7.13:
Softkey 1, “CCW”:
Rotates the picture counter-clockwise.
Softkey 2, “CW”:
Rotates the picture clockwise.
Press the softkeys and the picture will be
turned by 90°. The GVX will store the photo in
the new, rotated version.

To return to the viewing mode, press softkey 5,
