 +===== 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.
