* <font color='Indigo'>'''*-D0.0.jpeg'''</font> - disparity = 0, images are undistorted to a common polynom
* <font color='OrangeRed'>'''*.corr-xml'''</font> - ImageJ plugin's settings file?
* <font color='Maroon'>'''*-DSI_COMBO.tiff'''</font> - Disparity Space Image - tiff stack

* <font color='DarkGoldenrod'>'''*.obj, *.mtl, *.png'''</font> - OBJ format model with textures
* <font color='ForestGreen'>'''ml/*.tiff'''</font> - TIFF stack of pre-processed images for ML

* *.kml, rating.txt, thumb.jpeg - files, related to the online viewer only

==Stacked TIFF==

* The source files are processed using a plugin for ImageJ, the output file for each set is a tiff stack
* There are a few ways to view the stack:
** just open with ImageJ Oleg
