What does the Harsh Flash effect change?

Harsh Flash reshapes directional light, brightness falloff, and highlight placement across the photo, then blends the relit result with the original exposure. The strength control determines how much of that treatment replaces the unedited appearance.

Which photos work best with Harsh Flash?

Choose Harsh Flash for architecture with deep directional shadows, backlit portraits, or landscapes with a wide exposure range when the source has clear detail and balanced exposure. Start with a lighter setting if it contains heavily clipped highlights, crushed source files, or flat illustrations that contain little recoverable tonal information.
