FAQ

How is this different from brightness?

Brightness shifts every pixel uniformly; highlights are weighted above midtone so shadows stay untouched.

Can it recover blown highlights?

Slight clipping eases back, but pixels already clipped to pure white hold no recoverable data — avoid severe overexposure when shooting.
