--[[About this plugin
This plugin will add the new export module "fusion to DRI or DFF image".
----REQUIRED SOFTWARE----
align_image_stack
enfuse ver. 4.2 or greater
exiftool
----USAGE----
Install: (see here for more detail: https://github.com/darktable-org/lua-scripts )
1) Copy this file in to your "lua/contrib" folder where all other scripts reside.
2) Require this file in your luarc file, as with any other dt plug-in
On the initial startup go to darktable settings > lua options and set your executable paths and other preferences, then restart darktable
DRI = Dynamic Range Increase (Blend multiple bracket images into a single LDR file)
DFF = Depth From Focus ("Focus Stacking" - Blend multiple images with different focus into a single image)
Select multiple images that are either bracketed, or focus-shifted, set your desired operating parameters, and press the export button. A new image will be created. The image will
be auto imported into darktable if you have that option enabled. Additional tags or style can be applied on auto import as well, if you desire.
image align options:
See align_image_stack documentation for further explanation of how it specifically works and the options provided (http://hugin.sourceforge.net/docs/manual/Align_image_stack.html)
image fustion options:
See enfuse documentation for further explanation of how it specifically works and the options provided (https://wiki.panotools.org/Enfuse)
If you have a specific set of parameters you frequently like to use, you can save them to a preset. There are 3 presets available for DRI, and 3 for DFF.
target file:
Select your file destination path, or check the "save to source image location" option.
Unless "Create unique filename" is check, it will overwrite existing files
Set any tags or style you desire to be added to the new image (only available if the auto-import option is enabled). You can also change the defaults for this under settings > lua options
format options:
Same as other export modules
global options:
Same as other export modules
----KNOWN ISSUES----
Cannot handle spaces in image paths on windows machienes
Pops up multiple CMD windows on windows machienes
