俯瞰美国河流水系照片

              (中国四川 夏中华)

  河流水系(其结构:即源地、注入、流程、流域、支流及分布,以及落差等)是地壳运动后造物主的杰作,是由源头流向侵蚀基准面与山谷流水以及地下水汇集而形成,其形状受山脉走向制约,常见有树枝状、向心状、放射状、平行状、网状等。其描述含:河流长度、流向、流域面积、 支流数量及其形态、河网形态、宽窄、弯曲等。它的存在一直如同双面娇娃一般;安睡时,大都美得令人窒息,怒吼之时,那令人恐惧的破坏力绝对让人感到敬畏。

  那么如何去表现对这让人敬畏而又神奇大自然景象呢?用画面摄像还是用色彩和光影去摄影?我一直在思索!这次美国之旅感恩天时、地利、人和,给我带来颇丰的收获!

  下面这组壮美的河流水系自然奇景就是我在美国8000米高度上空所捕捉到的;动态、非平衡状态的河流水系受山脉影响,呈金黄色,放射状向下游河谷延伸、分流,造就出了独一无二又形态奇特、各异、简约干净的河流水系,水系上又折射衬映出蓝天里藏着的几朵白云,在阳光照耀下,在柔和的色彩下透露出一份祥和与宁静也仿佛一切的精灵都闪动着欢乐的双眼,高擎手臂飞舞呼唤着人间珍惜、保护,期盼着人类在母亲的怀抱中和谐共存!

  然而这些本不发光的河流水系又为何又呈现出光彩夺目耀眼的金黄色呢?是谁给它涂上了颜色呢?是摄影师的后期制作?这是太阳光变的戏法。

  我们知道太阳光是由多色光红、橙、黄、绿、蓝、靛、紫组成的,物体呈现色是由反射的色光所决定的,各种物体对光线的吸收和反射率各不相同,红色是67%,黄色是65%,绿色是47%,青色是36%,而其中红色和黄色对光线反射较强,易产生视感。当光这种电磁波沿着光程为极值的路径从一种介质射向另一种介质的交界面时,若介质吸收某种波长的光能较显较强,则不易被反射,反之则一部分光返回原来介质中,使光的传播方向发生了改变而形成反射,这就是说,当我们能够看到一些本不发光的物体如河流水系,在明净清澈被日光照耀时,被水吸收最少的红、绿光和黄光(反射了以550nm为中心波长)发生了光路变化,并以混合和叠的形式通过漫反射触发我们眼睛中的红色、绿色、黄色感光细胞,所以,在我们的眼睛看来河流水系就成了金黄色(黄色光 = 红色光+绿色光)殊不知这是眼睛欺骗了我们(因为我们的眼睛中只有红绿蓝三种感知颜色的感光细胞,而没有黄色感光细胞,如果红色和绿色都同时被激发,我们才会看到是黄色),它未如实反映情况的缘故,眼睛是可以被欺骗的,所以,只要在光学条件符合的前提下,当我们飞机位置在反射角刚好等于太阳光入射角时就能看到了那光彩夺目、金色耀眼有着诗人描绘不出的令人陶醉、向往、迷恋的意境美。

  这是一首保护完好纯自然河流水系的瑰丽颂歌,或是当今世界独一无二的照片,凝固了摄影者夏中华的思想和情感, 喻了自然默默的慷慨,隐喻了自然智慧丝毫不逊色于人类和令人敬畏的一面。同时也旨在惑你的灵魂而不是魅惑的你的眼睛,更希望读者能从摄影师的镜头中感到那份来自自然的魅力,而摄影师只是这魅力的传递者!因为他认为;奇妙的图片是好奇心的开始,观形、探究河流水系、水文特征是人类保护河流水系自然生态系统和科学利用水能蕴藏、河流航运价值等的前提。

Overlooking the river system in the United States

(zhong-hua xia) in sichuan province of China

River system, the structure, namely, source, injection, process, river, a tributary and distribution, as well as the head, etc.) is the masterpiece of crustal movement after the creator, is by the source water and groundwater flow to the base level of erosion and valley together and form, its shape, subject to the limit of the mountains toward, common have branches, to the heart, radial, parallel structure, mesh, etc. Described including: the length of the river, flows to, the basin area, branch number and its morphology, river morphology, size, bending, etc. It has been like double joon; Sleep, most beautiful suffocating, roar, the frightening damage absolutely let a person feel fear.

How can we show the awesome and amazing nature picture? Use a picture camera or a color and light to photography? I have been thinking! This trip to the United States gratitude, geographical and human conditions at present, bring me a lot of harvest!

The river system of a group of grandeur, natural wonders is in the United States I captured over 8000 meters high; Dynamic, non-equilibrium state of river water system influenced by mountains, golden brown, with radial to the downstream valley, shunt, have produced a unique and exotic, different forms, simple clean river system, on the drainage and refraction through out of hiding a few white clouds in the blue sky, in the sunshine, under the subdued color reveals a peaceful and quiet, also as if all the elves of flashing eyes of joy, flying high with arm Shouting to cherish and protect, looking forward to the human in harmony in the mother's arms!

(picture)

But these were not illuminated and why river system and present a brilliant brilliant golden color? Who give it a color? Post-production is a photographer? This is the sun of tricks.

We know that the sun is by the polychromatic light red, orange, yellow, green, blue, indigo, and purple, object rendering color is determined by the reflected light, various objects on the light reflectance and absorption of each are not identical, red is 67%, yellow is 65%, green 47%, blue is 36%, and the red and yellow to light reflection is stronger, is easy to produce visual sense. When the extremum of the electromagnetic waves along the optical path of light path from one medium into another medium interface, if the medium to absorb certain wavelengths of light is strong, is not easy to be reflected, the opposite part of the light to return to the original medium, make the direction of propagation of light has changed to form a reflection, that is to say, when we can see some of this light objects such as river system, was when the sun shines in clear clear, red, green and yellow light is absorbed by water at least (reflection for the center with 550 nm wavelength) optical path changes have taken place, and in the form of mixing and composite by diffuse trigger our photoreceptors in the eye red, green, yellow, and so, in our eyes seems river system became a golden (yellow light = red light and green light) but it's eyes deceived us (because our eyes have only red, green and blue three color perception of photoreceptor cells, without yellow photoreceptor cells, if the red and green were stimulated at the same time, we would see is yellow), it does not truthfully report the situation, the eye can be deceived, so, as long as meet under the premise of the condition of optical when we aircraft position in the Angle of reflection is equal to the sun when the incident Angle just can see the bright, golden bright has the poet paints out intoxicating, yearning, obsessed with beauty of artistic conception.

This is a well-preserved rosy carols for the pure natural river system, or the world's unique pictures, it set the photographer zhong-hua xia thoughts and emotions, great yu silently generous nature, metaphor natural wisdom not inferior to human being and a formidable side. Also aims to charm your soul rather than the charm in your eyes, more hope readers can feel that from the photographer's lens from natural charm, and the photographer is the charm of the relay. Because he thinks; Wonderful pictures is the beginning of curiosity, view, explore the river system, hydrological characteristics is human protection of river system natural ecological system and scientific use of water is the premise of value, river shipping, etc.
