 +===== How to save a Depth Map Image =====
 +
 +Normally the depth map that is computed internally by DMap is used only to construct the DMap output image and is not retained after the output image is constructed.
 +
 +However, you can optionally save the depth map by setting a couple of parameters __before__ you run a DMap operation, and then the DMap operation exports the depth map as a side effect.
 +
 +To make the settings, go to Options > Preferences > DMap Settings, then scroll down the panel so that you can see the checkbox labeled "Save depth map".  Click the box to put a checkmark in it.  Then specify a folder to contain the depth map, either by typing its full path such as C:\ImageFiles\ZSDepthMaps or by using the Choose button and then navigating to the desired folder.  
 +
 +It looks like this:
 +{{:stacker:docs:tutorials:tutorial003:savedepthmapcontrols.jpg}}
 +
 +With this setting made, click OK to close the Preferences dialog.
 +
 +Every time you run DMap after making this setting, the corresponding depth map will be saved as an image file in the specified folder.  The file name is same as the output image, with "_depthmap" added to it.  The file format is 16-bit TIFF, nominally RGB but with all components equal to the same value.  The pixel values range from 0 to 65535, corresponding to image numbers from 1 to N in the list of "Input Files" after stacking.  (Photoshop will show these pixel values as 0 to 255, following its 8-bit convention.)  To stop saving depth maps, just un-check the option.
 +
 +Note that "Save depth map" is a Pro-only option, which means that it requires Prosumer or Professional Edition to be used beyond a 30-day trial period.  There will be a popup message reminding you of this, the first time that you select the option.
