I would love to give my photos a dreamy effect like this. I can see there's some clarity reduction; what, in terms of highlights, shadows, lights, and darks, would the lighting look like? For instance,
highlights up, lights down, shadows up, darks down
or
highlights up, lights down, shadows down, darks up.
Additionally, would there be a contrast reduction or exposure boost, too? Or would these above changes alone achieve this effect?
