Combine highlight glow with a light blur for a soft, luminous surface.
When to use it
Backlit portraits, reflective objects and atmospheric interiors are useful starting points.
How to control it
In Edit → Film Effects → Creative, choose Diffusion. Amount blends the effect; Size changes its spread.
A starting approach
Set Size before Amount. Compare fine edges and skin texture so that the glow supports the image instead of hiding it.
Combine with intention
Choose one main direction first. Compare with the effect reduced or off before adding another treatment. Check the exported photograph as well as the preview.
