Pirelli also uses a technique that illuminates the tyre with three different light sources: diffuse light, and left and right grazing light
. A line scan camera, operating at one frame every 60ms, then captures three images under the different lighting conditions, to identify very small defects, such as small cuts.
'Grazing Light,' which opens this week at Leon Gallery in Makati, follows through the highly successful exhibit 'Afflictions of Glory.' Mounted last year also at Leon to mark the Philippine-American artist's birth centenary (1916-2016), 'Afflictions' was the first ever major show of Ossorio's work in the land of his birth.
'Grazing Light' will somehow build on Ossorio's conflicted obsessiveness, but with emphasis on his unique but very intense artistic techniques, such as his wax-resist painting method and his modern reinvention of medieval fresco technique as illustrated in his Victorias chapel mural.
As an indication, the quantities are for the contract period of the order of 200 grazing light
Ordinarily, you'd slew your telescope to a spot illuminated by the grazing light
of a rising or setting Sun, so that even small bumps cast long shadows on the lunar landscape.
Even illumination is recommended for planar areas, while grazing light is more suitable for textured walls.
In contrast, grazing light is better suited to accentuate spatial textures, such as masonry joints or rough cut stone.
Use uplights, downlights and spotlights to highlight plants and to create moon shadows on the ground, or a grazing light
to emphasise the texture of a wall or fence.
A grazing light
on a textured brick wall may be desirable, but the same light on an average gypsum board wall could be a disaster.
up a brick wall emphasises its texture.
When the curved walls of the circular antechamber slide open, visitors enter a spaceship-type black and white effects gallery where direct ambient light and grazing light
is demonstrated on eight different textured and smooth wall surfaces.
Halogen track lighting utilizing 50-W PAR 30 lamps provides grazing light
on the ceiling-suspended wood-slat scrim curtain, creating a dramatic backdrop for the reception desk.
