Darktable - reduce effect or reduce blend opacity?
1

Although I use darktable, I expect my question may apply to many other programs that have blending modes.  When I use a module, e.g. dehaze, darktable applies a default value. If I want to reduce the effect, I can reduce the effect slider - or, I can turn on the uniform blending and reduce the opacity.  Both methods work and seem to give similar results, but I'm not sure if there are any technical advantages or one method over the other.  On darktable youtube videos, I see both methods used.
