Setting working parameters

Press your particular <ALT> button
At the bottom of the screen you will see <ALT> against a blue background to indicate 'alternative menu mode' and 'Default script' or some other script name.
Press [Menu] to display the alternative configuration (CNF) menu (shown above) and disable the normal functions of the camera buttons.
Select 'Stereo' menu.

• SDM Header
  The information displayed at the top of the screen can be standard (FAST/DIRECT mode, focal-length, synch flash status,synch delay value), compact (textless focal-length and synch delay,synch flash status) or no header.
  
• Show SDM Configuratin
  
  
  
  
  To quickly see the current status of SDM, select 'Show SDM Configuration'.
  

• Synch Zoom
  Synchronised-zoom using the USB remote may be enabled or disabled.
  

• Zoom time-out
  If synchronised zoom is enabled, you may set a time for zoom-mode to be exited if remote-switch not pressed.
  
• Synchronisation
  
  
  
  'Synchronisation' opens the submenu that allows you to use the USB connection as a 'remote release' and to synchronise multiple cameras.
  If synch is enabled, the shooting sequence is paused until the remote switch is released.
  This applies to both Direct mode and running scripts in <ALT> mode.
  Synch delay is automatically enabled and its value set by SDM when using flash in Direct mode.
  You may set your own value to obtain a time-delay, for example.
  A synch coarse value of 50 provides a delay of 5 seconds after releasing the switch.
  The camera will take a photo after 10 seconds regardless of the delay set.
  When synch is enabled, 'Synch' will be displayed at the top of the screen together with the delay value.
  If no delay value is displayed, that means it is disabled.
  To speed the entering of large delay values, increase 'synch delay step-size' to a suitable value.
  Although not recommended, different models of camera have been synched by carrying-out synch tests and applying a delay to one of the cameras.
  SPM takes care of any image-size mis-match.
  It is possible to use synchronised flash with this setup by choosing menu option "Add user and flash delays".
  The automatically-calculated delay value for the chosen shutter-speed will be added to the delay required to synch the different cameras.
  
  
  

• Disable Deviation Guideline
  When an overlay grid is displayed on the right camera, a deviation guideline is adso normally displayed.
  Use this option to disable display of the guideline.

• Playback mode
  On some cameras you can take a pair of images by shifting a single camera and view in playback mode in stereo.
  Although intended for showing the registration-accuracy of the pair you can view as monochrome or colour anaglyph with red/cyan glasses.
  This is obviously more effective on larger screens.
  You could also use this feature to quickly demonstrate the concept of stereo imaging to interested individuals.
  You may also view the centre of the images side-by-side.

• Twin Camera position (Left or Right)

• Camera orientation (Vertical or Horizontal)

• Camera rotated (to the Left or Right)

• Camera spacing
  Spacing for twin-rigs or camera-shift for a single camera.
  Lower limit is 1mm.

• Deviation factor
  Image-width divided by this number is the maximum deviation that you will accept for eventual stereo-viewing.
  Lower limit is '10', default is 25.

• Nearest-subject factor
  Camera separation times this factor is how far away nearest subject should be.
  Lower limit is '15'.
  '30' for general use, as small as '15' for close-ups.

• Data step-size
  To make manual setting of distance quicker on cameras that do not have a zoom lever, choose from 1,10,100,1000 or 10000mm steps.

  
  On cameras with a zoom lever, increment value is displayed top-left and may be increased or decreased with the lever.
  

• Set focused distance
  Set the focused distance using steps of the above-set size.
  This is also used as the manually-entered near distance on some displays.

• Far-distance manual value.
  Manually enter a value rather than using cameras autofocus value.

• Focus mode
  In <ALT> mode, if you press the DISPLAY button when the camera is in manual-focus mode, the focus will move to infinity, hyperfocal distance or the manually-set distance.
  Choose from INF, HYP or MAN here. The mode will be displayed on the screen.

• Save XML file
  Save shooting data, including some not displayed on screen, as an XML file.
  'XML' is displayed on the screen.
  A sample style sheet is provided to display the image and associated data.

• Save XML with JPG
  If the XML files are saved with the JPG images and the file 'stereo_data.xsl' is also located in the same folder as the images, by double-clicking the XML file while the card is still in the reader your image will be displayed together with all of the stereo data.
  Otherwise, the files are saved in folder 'DCIM/SDM'.
