208 C H A P T E R 7 The Stereo Data Maker (SDM)readily executed. This feature and the excellent remote features (includingsupport for the Ricoh CA1 remote control) are the reasons why the SDM hasso many users in the KAP community. However, recent versions of theCHDK have adopted the SDM remote functions and offer almost the samefunctionality.A specialty of the SDM is the use of the blue LED as a serial interface tohook up external devices, such as motorized camera rigs or robotic pan-orama heads. Finally, a recently introduced feature of the SDM is the sup-port of Digiscoping, i.e., connecting a camera to a telescope.7.4 OperationUsing the camera under the SDM is quite similar to using it under theCHDK. There is an mode which you can enable via the ALT button(chapter 4). Pressing the MENU button in mode leads to the SDMmenu.The various indicators are also organized differently. There is an SDMheader line showing several entries, such as shooting mode, zoom value,and focal distance. You can configure this line under ALT > MENU > Stereo >SDM Header.Many functions are invoked through key shortcuts instead of menuentries. For example, enabling or disabling Overrides is performed by half-pressing the shutter button and pressing FUNC/SET. An indicator at the leftside of the display shows MAN when Overrides are enabled, and OFF whenOverrides are disabled.Here are some more key shortcuts. They are worth remembering be-cause they can make life easy. However, you can always look them up withthe Text File Reader (ALT > MENU > Advanced Menu > Text file reader > Opennew file…). File CHDK/TEXTS/SHORTCUT.TXT lists all of these shortcuts.In Record mode, the following key shortcuts are available:f ALT-MENU: Invokes the SDM menu.f ALT > FUNC/SET: Switches the OSD on/off with a short click on FUNC/SET. A longer press switches the Edge Overlay on/off.Note: This key combination is used in standard CHDK for loading ascript. Under the SDM, you must use the menu function ALT > MENU >Scripting > Load script from file…, instead.f ALT > LEFT: Browses OSD information screens backwards. These screensdisplay vital data for different purposes such as digiscoping or stereoset-up organized in multiple pages.f ALT > RIGHT: Browses OSD information screens forwards.Figure 7-2The SDM main menu looks differentcompared to the CHDK menu becausethe already well-known functions aregrouped differently. |
