Background technology
Optical filter is plastics or sheet glass adds special dye and makes, and Red lightscreening plate can only allow HONGGUANG pass through, and so on. The absorbance of sheet glass is originally few with differential air, all colored lights such as through, so being transparent, but after having contaminated dyestuff, molecule structure change, refractive index also changes, to some coloured light by just changing. Such as beam of white light passes through blue color filter, and injection is a branch of blue light, and green glow, HONGGUANG are few, most of is ended by optical filter.
The effect of optical filter is very big. It is widely used in photographic circle. Landscape paintings of some photographies great masters' shooting, why is main scape always so prominent, is how to accomplish? this has just used optical filter. Such as you want to start auction a Hemerocallis citrina Baroni with camera, and background is blue sky, greenery, if according to usual bat, cannot highlight " Hemerocallis citrina Baroni " this theme, because the image of Hemerocallis citrina Baroni is prominent not. But, if putting a yellow filter before camera lens, stopping the blue light that green glow that a part of greenery scatter, blue sky scatter, and allowing the gold-tinted that Hemerocallis citrina Baroni scatters pass through in a large number, so, Hemerocallis citrina Baroni just seems fairly obvious, highlights " Hemerocallis citrina Baroni " this theme.
