What does the Glass Caustics effect change?

Glass Caustics introduces a shaped light or shadow layer with controlled direction and falloff, integrating the overlay with the photograph instead of masking it uniformly. The strength control determines how much of that treatment replaces the unedited appearance.

Which photos work best with Glass Caustics?

Choose Glass Caustics for landscapes that need visible weather, seasonal campaign imagery, or product scenes that need environmental depth when the source has clear detail and balanced exposure. Start with a lighter setting if it contains crowded frames, critical documentary images, or sources whose existing weather and light direction contradict the added layer.
