My very first impressions after getting to know and playing with sigmoid for about an hour and not knowing if this module comes with a certain required workflow:
- I think that a category of people will like this one; Just one simple slider and not all the complexity and fine-tuning that filmic rgb or the tone curve (in part) offer.
- I find the slider to be very sensitive, even the smallest change possible (+/-0.01) is noticeable on my good, but not professionally good, monitor.
- I get the impression that sigmoid (de)saturates too aggressively when changing the default setting. This can get ugly fast (have a go at the Noctilucent clouds image).
The above comments are based on very basic edits (wb + exposure only) and then comparing sigmoid with the filmic rgb and the tone curve. I do not use the base curve so I skipped checking against that one.
Just from my point of view I would most likely not be using this module. Not because it isn’t any good (which my above “tests” will not really show if that would be the case), but because I like/need the finer control that the other modules offer. People that want quick edits/results might be rather happy with this one, though.
