    This lesson will help you learn and practice  FLASH & DISTANCE.  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 FLASH & DLIDS 。 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 。 审查和学习这些资源也很重要 。 您将有机会在 BUILD 您的 SKILLS 中练习 。 最后, 回答您在此专题结尾处的发现中的问题, 请务必包含您从 Explore Resources 中学到的信息 。


    GET THE BASICS 
    You've learned that your digital camera's flash can provide more light when needed. However, flash has a limitation - distance from your subject. This applies both to being too far away and too close.
    ::获取你所学到的图像, 您的数字相机的闪光可以在需要时提供更多光亮。 但是, 闪光有一定的局限性 —— 距离您的对象。 这既适用于距离太远, 也适用于距离太近 。

    The amount of light from your flash provides drops off quickly as the subject is further from the camera. By about 10-15 feet away, the subject gets little or no light from the flash. Here's a flash photo that shows what happens when the subjects are too far away. Notice that the flash is unable to illuminate the subjects at this distance. It also means that all those people in huge stadiums who shoot flash photos of action far away on the field are getting no benefit from their cameras' flashes. All they're doing is illuminating the backs of the heads of the people in front of them.
    ::您闪光的光量在镜头之外, 闪光的光量会快速下降。 在大约10至15英尺之外, 对象会从闪光中得到很少或没有光。 这是一张闪光照片, 显示对象太远时发生的情况。 请注意闪光无法在此距离照亮对象。 这还意味着所有在远在现场拍摄闪光动作照片的大型体育场里的人, 都无法从相机的闪光中得益。 他们所做的只是照亮前面的人们的头部的背部 。

    use of flash from too far away


    The closer your flash is to the subject the stronger the effect of the flash. If you are too close and the flash is too strong, the subject will be blown out. The highlights on the face, forearm, and hands in this photo are blown out. [Note: The original photo has been edited to create the blown out appearance.]
    ::您的闪光距离越近, 闪光的效果就越强。 如果您太近, 闪光太强烈, 主题就会被吹灭。 照片上的脸、 前臂和手的亮点会被吹灭。 [注意: 原始照片已被编辑, 以创造被吹出的外观 。 ]

    You may be able to compensate for being too far from, or close to, your subject by increasing or decreasing the flash intensity using your digital camera's  +/– flash options  (see previous lesson).
    ::使用数码相机的 + / - 闪光选项(见前一课), 提高或降低闪光强度,

    BUILD YOUR SKILLS    
    To build your flash skills, you're going to shoot two or more sets of three photos.  Choose a dimly-lit situation for each set.  In each set, use your digital camera's flash and shoot from too far away, too close, and in-between positions.
    ::为建立你的闪光技能, 您将拍摄两套或多套三张照片。 选择每套照片的亮度。 在每套照片中, 使用数码相机的闪光, 从太远的地方拍摄, 太近的地方拍摄, 位置之间 。

    Review your flash photos. Select one set of photos that best demonstrates the three distance positions. 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.
    ::重新审视你的闪光照片。 选择一组最能展示三个距离位置的照片。 与老师分享您的照片, 并准备讨论他们如何显示您学到的东西。 将您的照片下载到电脑上, 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

    • What happens to a photo when the subject is too far away from your flash?
      ::当对象离你的闪光太远时 照片会怎么样?
    • What happens to a photo when the subject is too close to your flash?
      ::照片离你的闪光太近会怎么样?
    • For your selected set of photos, describe how the three distance positions affected the photos.
      ::对于您选中的一组照片, 请描述三个距离位置是如何影响照片的 。
