taustakiirgus

Taustakiirgus is a term used in Estonian graphic design and digital media to describe a background glow effect applied to elements such as images, panels, or typography. The effect creates a soft radiance around or behind content, helping to separate foreground elements from the backdrop and to establish mood or atmosphere.

Etymology and usage: The word is a compound of tausta (background) and kiirgus (glow or radiance). In design discourse it denotes a controlled glow that is usually subtle, warm or cool in hue, and is implemented to enhance depth rather than to illuminate the subject directly.

Applications: In graphic design and branding, taustakiirgus is used behind headlines, logos, or hero images. In photography and film, it refers to background lighting that produces a halo or aura around the subject. In web design, it is recreated with gradients, blur, and glow effects in CSS or image editing software to create separation and atmosphere.

Considerations: Appropriate intensity, color balance, and contrast are essential for readability and accessibility. Overuse can create visual noise or reduce legibility on small screens. Performance should be considered in web contexts, as heavy glow effects may impact rendering.
