Prompt

Apply Bloom to make the brightest highlights radiate soft, luminous halos into neighboring areas. Spread warm whites and existing highlight colors gently beyond their edges, with smooth falloff and additive brightness. Keep shadows comparatively crisp and avoid uniform fog. Preserve the original subject and composition.

Paste it into LetzAI with your own image to apply the effect ↗

Identify

Bright parts of the image radiate into their surroundings.

Principle

A threshold image1 is softened and additively mixed2.

Try it out

Change the highlight threshold.

Classification

Schematic visualization, not neural inference.

02 Cone Nebula (NGC 2264) Star-Forming Pillar of Gas and DustBright stars in the nebula exhibit a soft glow that extends into dark regions. This demonstrates the additive blending of a blurred highlight threshold into the base image.NASA, H. Ford (JHU), G. Illingworth (UCSC/LO), M.Clampin (STScI), G.

05 Solar eclipse taken from Artemis II - April 2026A bright light source appears behind a dark celestial body. The intensity of the light overflows its edges, creating a soft glow that bleeds into the dark silhouette, demonstrating the characteristic light bleeding of digital bloom.NASA · Public domain · Wikimedia Commons
