Flat white reflects the light in the room without shiny, gloss reflections from the ceiling.
Since gloss is a specular reflection component of the illumination lights, a camera with a very high dynamic range is required in order to measure the gloss luminosity.
Furthermore, since each tissue scatters light internally, if the tongue surface is dry, the tissue does not generate the gloss caused by the reflection of incident light.
The homogeneous diffuse light, together with the calibration steps, ensures an optimal dynamic range and minimizes shadows and shading effects as well as specular reflection and gloss-related effects.
"The Annotated Classic Fairy Tales" (Norton; $35), edited by Maria Tatar, a professor at Harvard, is the latest in Norton's long line of annotated classics, a form that Martin Gardner invented and perfected, forty years ago, with "The Annotated Alice" and "The Annotated Snark": a familiar text with lots of glosses, explanations, and reflections.
The long-delayed follow-up to her 2003 debut Solo Star, Sol-Angel is savvy R&B with a gloss you can check your reflection in, but it falls short of what she intended: to make the record Dusty Springfield or Minnie Riperton would have made, were they around in 2008.
The brightness of a pigment is due to diffuse reflection while the gloss is due to specular reflection.
The base coating of the coating system is a gloss lacquer with a Cr reflection layer.
Caroline Sullivan of The Guardian called its music "savvy R&B with a gloss you can check your reflection in", but ultimately observed "a lack of both memorable tunes and the steely spined ardour that makes Beyoncé so compelling".
In order to record gloss, we record the specular reflection light with a camera by irradiating light that is strongly directed at the tongue surface.
