  • 光线方向

    This lesson will help you learn and practice  DIRECTION OF LIGHT.  In GET THE BASICS, you'll get explanations and photos to build understanding. In EXPLORE, you'll find additional online resources to learn more. It's important to review and learn from these resources also! You'll have opportunities to practice in BUILD YOUR SKILLS. Finally, answer the questions in RECORD YOUR FINDINGS at the end of this topic, be sure to include information you learned from the Explore resources.
    ::这将帮助您学习和练习光源方向。 在获取 BASICS 中, 您将得到解释和照片来建立理解。 在 Explore 中, 您会找到更多的在线资源来学习更多。 还要从这些资源中学习 。 您将有机会在 BUILD 您的 SKILLS 中练习 。 最后, 请回答您在此专题结尾处记录您发现的问题, 请务必包含您从 Explore 资源中学到的信息 。


    GET THE BASICS
    You've learned that light is essential to photos. Too little light... your photos will be dark or black. Too much light... they could be blown out white. So just make sure that there's enough light, right? No, there’s actually a lot more to it!
    ::获得你所学会的光是照片必不可少的。 太小的光... 你的照片是黑或黑的。 太多的光... 它们会被吹出白色。 所以只要确保有足够的光, 对不对? 不, 实际上还有更多。

    Let's start with your eyes. Your eyes are offset from each other, so each eye sees things from a slightly different angle. When your brain combines the signals from both eyes, the result is seeing the world as 3-dimensional (3D) - not just vertically and horizontally in one plane (remember planes from geometry?) but closer and further away as well. This is called depth.
    ::让我们从你们的眼睛开始。你们的眼睛互相抵消, 所以每只眼睛都从一个稍微不同的角度观察事物。 当你们的大脑将两只眼睛的信号结合起来时, 其结果就是将世界看成三维(3D)-- 不只是垂直和水平在一个平面上( 记得几何的平面吗? ) , 而是更近更远。 这叫做深度 。

    An photo, on the other hand, is 2-dimensional (2D). It is all in one plane, so there is no depth. So, how can you make your photos look 3D? You've already learned about how a larger aperture setting creates a narrower depth of field. Your subject can be in focus while the foreground and background is out of focus. This is one way to create a 3D look.
    ::另一方面,照片是 2 维 (2D) 。 它全部在一个平面上, 所以没有深度 。 因此, 您如何使您的照片看起来 3D ? 您已经学会了更大的孔径设置如何创造更窄的字段深度 。 您的话题可以在前景和背景脱离焦点时焦点集中 。 这是创建 3D 外观的一种方法 。

    Another way is by controlling the direction of light. When light hits something solid, a shadow is created by blocking the light. Shadows give the appearance of 3D. Here's a photo with light coming from the front of the subject. There are few or no shadows, so the photo looks 2D.
    ::另一种方法是控制光线的方向。 当光线击中固体的东西时, 屏蔽光线会形成一个阴影。 阴影会显示 3D 的外观。 这里有一张照片, 光线来自主题的前面。 光线很少或没有, 所以照片看起来是 2D 。

    What if the light comes from the left of the subject, creating shadows on the right? This photo looks 3D! The difference is the direction of light.
    ::如果光线来自主题的左侧, 在右边创造阴影呢? 这张照片看起来是 3D! 区别是光的方向 。

    portrait with light from the left


    Light from the right of the subject creates shadows on the left. Again, giving a 3D appearance.
    ::主题右侧的光线在左侧创造阴影。再次显示三维外观。

    Light from overhead can also create shadows and 3D.
    ::上面的光也能创造阴影和3D。

    When you were little, did you ever hold a flashlight under your chin to try and look scary? Well, you were using light from below the subject to create shadows and 3D.
    ::当你小的时候,你有没有用手电筒 在下巴下巴下手电筒 来吓唬人?

    a scary look with light from below


    You can see that the direction of light in photos is extremely important. It can create shadows, a 3D appearance, and even affect the mood of the photo.
    ::你可以看到照片中的光线方向是极为重要的。它可以创造阴影,3D外观,甚至影响照片的情绪。


    EXPLORE 
    Learn more about the direction of light at The direction (position) of light from Kodak. [Don't worry about the references to using a flash. That will be addressed in the next chapter.]     :

    ::Explore从Kodak了解更多关于光的方向(位置)的灯光方向(位置)的更多信息。 [不用担心使用闪光的引用。 这将在下一章中讨论 :

    Now play with an interactive direction of light tool at Light Direction from PhotoMatters:

    ::现在在光线方向使用一个互动的灯光工具,


    BUILD YOUR SKILLS 
    To build your direction of light skills, you're going to shoot examples of subjects with light from the front, left, right, overhead, and below - two photos for each direction.
    ::为建立光学技能的方向, 你将拍摄从前、左、右、上到下各取两张图片, 从前、右、右、上到下各取两张。

    Review your direction of light photos. Select ONE photo for EACH direction of light - front, left, right, overhead, and below.  Share your photos with your teacher, and be prepared to discuss how they show what you’ve learned.  Download your photos to a computer to keep them for the portfolio you’ll create in the end-of-course final project.
    ::重温光照的方向。 选择一张照片, 用于灯光的每个方向- 前、 左、 右、 右、 上下。 与老师分享您的照片, 并准备讨论他们如何展示您学到的东西。 下载您的照片到电脑上, 以保存您在期末最终工程中创建的投资组合 。


    RECORD YOUR FINDINGS
    ::记录你的调查结果

    • When it comes to depth, how are photos different from seeing things with your own eyes?
      ::在深度方面, 照片与用自己的眼睛看事物有何不同?
    • How does the direction of light affect photos?
      ::光线的方向如何影响照片?
    • Describe how the direction of light in each of your selected photos creates a 3D appearance.
      ::描述您所选照片中的光线方向如何产生 3D 外观 。
