Lumiere can produce sophisticated specular blooms, flared highlights and diffused glows combined with total control over every possible variable, all at the artist’s fingertips. Lumiere works on image luminance just like real glows do. The brighter areas of the image are processed into beautiful glows.
Lumiere offers professional-grade masking controls for isolated glows. The artist can specify a hotspot and falloff radius as well as image coordinates for advanced masking operations. Ten different luma conversion algorithms are available based on various industry standardized color spaces. Lumiere provides two highly optimized diffusion algorithms with independent axis control and multi-pass operations. Glow-specific features such as gamma adjustment, saturation control, chromatic aberration, pixel noise capabilities and diffusion color tinting provide unsurpassed features for generating ultra-realistic glow effects.
Lumiere has been developed for the professional digital imaging industry and therefore supports both 8 / 16 bits per channel color modes using 100% multithreaded rendering capabilities. A highly adjustable and resizable preview window instantly provides progress, zoom, image fit, realtime operations and statistical information after each pass.
