Good question :)
darktable (mostly) uses an unbounded color workflow, which means that L
values outside their normal definition range, i.e. above 100, are
handled like any other values.
The threshold parameter tells the module above which L value a pixel
should be subject to color reconstruction. Due to the unbounded nature
of the pixelpipe there is no reason to set this to 100 as a hard upper
limit. In real life you will probably find few cases with threshold
values above 100.

Hi all,
I've been questioned over something I said in ep022 of my video series,
regarding the threshold slider in the Colour reconstruction module.
Can anyone educate me on why the slider can be set to values higher than
100%?
Thanks in advance.
Cheers,
Bruce Williams
