bagliore

Bagliore is an Italian noun that denotes a bright, often transient light. It can refer to a glow, glare, or flash produced by a source such as a flame, a lamp, or the sun when it shines through mist. The term covers a range of intensities from a soft halo to a strong blaze and is used both in literal descriptions and in figurative language, for example to speak of the bagliore of dawn or a distant lighthouse beam.

In everyday Italian, bagliore is often paired with adjectives to convey quality of light, such as dorato (golden), intenso (intense), or tenue (soft). In technical contexts, the word is commonly translated as glare or bloom. In photography and cinematography, bagliore can refer to haloing or lens flare around bright areas, a phenomenon produced by optical elements or sensor saturation. In astronomy and atmospheric science, it is used to describe diffuse light around luminous sources caused by scattering in the atmosphere.

Bagliore also appears in poetry and literature as a metaphor for hope, revelation, or divine illumination, sometimes contrasted with darkness. The word forms bagliori in the plural to describe multiple glows or flashes.
