Preset Opacity

[Dan The Photo Man]

Hello!  I am new to Lightroom and curious how to reduce the opacity of a Preset once applied?  If I don't like a Preset at full-stregnth, I asume there is a way to fade it back until I like the look?  And just to be clear, I am using Lightroom and not Lightroom Classic.

No. No way. Presets are fixed in their settings- Apply a Preset and the Develop sliders (and other develop settings: Tone Curve, Split Toning, etc) assume the settings defined in the Preset.

You might see some provided Presets with various settings eg. Vignette: Light, Medium, Heavy.

You can apply a Preset, adjust the sliders (and other) settings, then Save your 'weaker' (or 'stronger') version of the Preset.

(Some Profiles OTOH, can have and 'Amount' slider that adjusts the Profile effects.)
