    This lesson will help you learn and practice  FLASH MODES.  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 模型。 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 。 同样重要的是要审查并学习这些资源 ! 您将有机会在 BUILLD 中练习。 最后, 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
    In the previous chapter, you learned a lot about light. There be times when you want to shoot a photo and there won't be enough light. You'll need some extra light. That’s the purpose of your digital camera’s flash.  When you use flash, your camera supplies a brief burst of light timed with the digital camera shutter .
    ::在上一章中,你学到了很多光学知识。有时你想拍摄一张照片,但光线不够。你需要一些额外的光线。这是你数字相机闪光的目的。当你使用闪光时,你的相机提供一阵光亮,与数码相机的闭门连接。

    Knowing the flash settings for your digital camera is important. The most common setting is toggling between Off, On, and Auto Flash modes. Icons for these settings may vary, but they generally look something like these:
    ::了解数字相机的闪光设置很重要。 最常见的设置是在 Off、 On 和 Auto Flash 模式之间切换。 这些设置的图标可能不同, 但通常看起来类似 :

    Off, On, Auto Flash icons


    Sometimes using your digital camera's low light setting produces a better photo than using the flash. In that case, you would set flash to Off, so it wouldn't flash. Other times, you may need just a little boost and can set the flash to On, so it will flash regardless of other settings. If you're not sure, leave your flash set to Auto and the camera will decide if flash is needed for your photo.
    ::有时使用数码相机的低灯光设置, 产生比使用闪光更好的照片。 在这种情况下, 您会设置闪光点, 这样它就不会闪亮。 有时, 您可能需要稍加推动, 并且可以将闪光点亮到 On 上, 这样它就会闪亮, 不论其它设置。 如果您不确定, 将闪光点留给 Auto , 相机将决定照片是否需要闪光点 。

    In addition, many digital cameras have +/– options that adjust the flash intensity. See if yours has a +/– flash option. If it does, you can increase the flash intensity with the + and decrease flash intensity with the –. 
    ::此外,许多数字相机都有调整闪光强度的 + / — — 选项。 看看您是否有 + / — 闪光选项。 如果有,您可以通过 + 来增加闪光强度,也可以通过 - 来降低闪光强度。

    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, shoot with each of the three main flash modes - Off, On, and Auto Flash.
    ::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, 使用三种主要闪光模式- 关闭、 打开和自动闪光 。

    Review your flash photos. Select one set of photos that best demonstrates the three settings .  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.
    ::查看您的闪光照片。 选择一组最能展示这三种设置的照片。 与您的老师分享您的照片, 并准备讨论他们如何展示您学到的东西。 将您的照片下载到计算机上, 以保存您在期末最终工程中创建的投资组合 。
