Add the following line to .config/darktable/luarc to enable this lightable module:
|
|
require "exportLut"
|
|
|
|
Given a haldCLUT identity file this script generates haldCLUTS from all the user's
|
|
styles and exports them to a location of their choosing.
|
|
|
|
Warning: during export if a naming collision occurs the older file is automatically
|
|
overwritten silently.
