to get a completely clean screen is to switch off the CHDK OSD com-
pletely (see above).
f
Center Menu . Displays the CHDK menus in the center of the screen if
switched on. If switched off, the CHDK menus are aligned to the top of
the screen.
f
Auto select 1st entry @ menu . When switched on, the first item of a
freshly opened menu is selected automatically. If switched off, no item
will be selected.
f
Enable Symbols . Determines whether symbols should be shown at the
beginning of each menu item. I find the information value of these
symbols rather limited and I can read the menu easier without the
symbols.
f
For the User Menu entries, please see section 4.2.5.
f Show State Displays . Determines whether the settings made in the
submenus Extra Photo Operations (section 4.3.1) and Custom Curves
(section 4.3.8) should be displayed on screen.
f
Show temperature . Determines if and when temperature should be dis-
played on screen ( Off , Optical , CCD , Battery , All ). This can be useful
when operating in a very hot or cold climate. (The optical temperature
is the temperature of the lens elements and is the closest one to the
environment temperature.) The temperature reading is in degrees
Celsius if the following menu entry
in Fahrenheit is not switched on.
f
OSD Layout Editor . This entry allows you to modify the layout of the OSD
information items on the screen. For this purpose, the CHDK organizes
the information items into groups: histogram, DOF calculator, exposure
status display, remaining RAW images, miscellaneous values (focal
length and other values), battery symbol, memory card symbol, vertical
memory usage bar, horizontal memory usage bar, battery text, memory
usage text, clock, temperature, remaining video time, EV correction
factor photo, and EV display video. By pressing the
FUNC/SET key repeat-
edly, you can select between these groups in the given sequence. The
selected group is shown with a green frame. To modify the position of
the selected group on the screen, simply press the
LEFT , RIGHT , UP, and
DOWN buttons. You can leave the editor with the MENU button.

DISP button.
