    WHAT IS A JPEG?
    JPEG stands for Joint Photographic Experts Group and is the most common format for digital photos. A JPEG can display millions of colors, so it's perfect for photos. There are other image formats that also display millions of colors, but JPEGs are compressed to create smaller image files while still looking good. Compression allows you to save more photos in less space. You'll learn more about compression - good and bad - later in this chapter. File format extensions most commonly associated with JPEG photos are .jpeg and .jpg .
    ::JPEG是什么? JPEG 代表联合摄影专家组, 是数字照片最常见的格式。 JPEG 能够显示数百万种颜色, 因而对照片来说是完美的。 还有其他图像格式也显示数百万种颜色, 但 JPEG 压缩后可以创建更小的图像文件, 同时看起来还不错 。 压缩允许您在更小的空间里保存更多照片 。 您可以在本章稍后了解更多压缩( 好的和坏的) 。 通常与 JPEG 照片相关的文件格式扩展是 .jpeg 和.jpg 。

    BATTERY
    Digital cameras require batteries to function. Most use rechargeable batteries. However, some use rechargeable battery packs or regular replaceable batteries.
    ::数字照相机需要电池才能正常运转,大多数使用可充电电池,但有些使用可充电电池包或常规可替换电池。

    MEMORY CARD
    Most digital cameras store images on a removable memory card. Common digital camera memory card formats include SD (Secure Digital), MS (Memory Stick), xD (Extended Digital), and CF (Compact Flash). Memory cards come in different capacities, measured from small to large: MB (megabytes) to GB (gigabytes). The larger the capacity, the more images the card will store.
    ::MEMORY CARD 多数数字相机将图像存储在可移动的记忆卡上。 常见的数字相机存储卡格式包括SD( 安全数字 ) 、 MS( 记忆棒 ) 、 xD( 扩展数字 ) 和 CF( 复合闪电 ) 。 记忆卡以不同的能力出现, 从小到大测量: MB( 兆字节) 到 GB( igigabytes ) 。 容量越大, 该卡将存储的图像就越多 。

    There's more to it though. Memory cards are also rated by speed. Unfortunately, there are several rating scales - megabytes per second (MBPS), the "x" suffix following a speed number, and class rating - but the easiest to understand, and most commonly used, is class rating. A class 10 card has a minimum data transfer rate of 10 MBPS while a class 2 card has a minimum data transfer rate of 2 MBPS. Don't worry about what MBPS actually means, just know that 10 is a lot faster than 2. This is important. If you are shooting large, high quality photos or high definition video, as many up-to-date digital cameras can do, you should go for a higher class with more speed. Check your digital camera's user manual for memory card speed requirements. You'll also learn more about image size and quality in the third lesson in this chapter, Resolution and Compression.
    ::更多的是。 记忆卡也被按速度定级。 不幸的是, 有几个评分尺度 - 每秒有兆字节( MBPS ) , 速度数后有“ x” 后缀, 级级评分, 但最容易理解和最常用的是等级评分。 10级卡的最低数据传输速率是10 MBPS, 而2级卡的最低数据传输速率是2 MBPS 。 不要担心 MBPS 实际意味着什么, 只要知道 10 远快于 2 。 这很重要。 如果您拍摄大、 高品质的照片或高定义的视频, 您应该像许多最新的数码相机一样, 以更快的速度进入更高的级别。 检查您的数码相机用户手册, 以便了解记忆卡速度要求 。 您还可以在本章、 分辨率 和 压缩第三课中学习更多图像大小和质量 。

    CLEANING YOUR CAMERA LENS
    If your camera lens is dirty, it’s like shooting photos through a dirty window. So, before you start, be sure your camera lens is clean. However, DON’T start wiping off the dirt, as this can scratch the lens and give you worse images than just having a dirty lens. Also, DON’T spray the lens with compressed air, as this can force dirt and dust inside the lens housing.
    ::如果你的相机镜头是肮脏的,它就像在肮脏的窗口里拍摄照片一样。所以,在开始之前,请确保相机镜头是干净的。 但是,不要开始擦掉泥土,因为这可以刮掉镜头,给你的图像比有肮脏的镜头还要糟糕。 另外,不要用压缩的空气向镜头喷射镜头,因为这可以迫使镜头内有泥土和尘土。

    How do you clean a camera lens? [1] Carefully, blow away any grit or dust, or brush it away with a camel’s hair brush made for camera lenses. [2] Gently wipe the lens surface with a clean, soft, lint-free cloth, like a microfiber cloth for cleaning eyeglasses. [3] If needed, use a little lens cleaning fluid (or, in a pinch, water) applied to the cloth. [4] Consider buying a lens-cleaning tool that has a brush on one end and a lens pen on the other end (about $8).
    ::如何清洁照相机镜头？[1]小心地吹走任何沙砾或灰尘，或者用相机镜头用的骆驼毛刷把它们刷掉。[2]用干净、柔软、无绒的布轻轻地擦拭镜片表面，就像清洁眼镜的超细纤维布一样。[3]如果需要，使用少量的镜片清洗液（或者，在必要的时候，水）涂抹在布上。考虑买一个一端是刷子，另一端是镜头笔的镜片清洁工具（大约8美元）。

    PHOTO PREVIEW, PLAYBACK & DELETE
    Digital cameras have LCD (liquid crystal display) screens. The LCD screens are used for previewing images as you shoot. Another use for the LCD screens – and one advantage of digital photography – is that after shooting a photo, you can see it right away instead of taking in film for processing and waiting for the photos to be developed. Your digital camera has a button to switch between camera and playback mode. Often the button is marked with a triangle icon, like the Play button on a DVD or BlueRay player. Locate your camera's playback button.
    ::PHOTO PREVIEW, PLATOBACK & DELETE 数字相机有液晶显示屏。 LCD 屏幕在拍摄时用于预览图像。 LCD 屏幕的另一个用途 — — 也是数字摄影的一个优点 — — 是在拍摄照片之后,你可以马上看到它,而不是拍摄胶片,以便处理和等待照片的开发。你的数码相机有一个按钮可以在相机和播放回放模式之间切换。这个按钮通常用三角图标标记,如DVD 或 BlueRay 播放器上的播放按钮。定位您的相机的回放按钮。

    In playback mode, you'll be able to delete photos. Your camera has a delete button that usually has an icon of a trash can on it. Locate your camera's delete button.
    ::在播放模式下, 您可以删除照片 。 您的相机有一个删除按钮, 通常有垃圾桶的图标 。 定位相机的删除按钮 。

    One more thing before you start shooting photos... Most digital cameras have an auto-focus mode for ease of use. When you shoot a photo, try pressing the shutter button halfway to allow the camera to automatically focus the image. Once the image is focused, press the shutter button the rest of the way to shoot the photo.
    ::在你开始拍摄照片之前,还有一件事... 大多数数码相机都有自动聚焦模式,以便于使用。 当你拍摄照片时, 尝试按下百叶窗按钮, 以使相机能够自动聚焦图像。 一旦图像被聚焦, 按下百叶窗按钮, 其余的按钮拍摄照片 。

    Now, shoot some photos. Don’t worry about the elements of good photo composition. You’ll learn about these in the chapters to come. For now, just get to know your digital camera and have some fun.
    ::现在,拍摄一些照片。 别担心好照片成份的元素。 你会在即将到来的章节中了解这些内容。 目前,你只要了解你的数码相机并玩得开心。

    After you shoot some photos, switch to playback mode and view your photos. Select a photo you don’t want, and delete it.
    ::在拍摄一些照片后, 切换到播放模式并查看您的照片。 请选择您不想拍摄的照片, 然后删除它 。

    SHARE YOUR PHOTOS
    Photos are stored as JPG images on your digital camera’s memory card, but there will be times when you will want to share photos with other people - like your teacher. There are several ways to share your photos.
    ::将您的照片作为 JPG 图像存储在数码相机的记忆卡上, 但有时您会想与其他人分享照片, 比如您的老师。 分享您的照片有几种方式。

    One way to share your photos is by downloading them to a computer and copying them to a portable flash drive. When you download photos from your camera to a computer, you are actually copying them from one location to another. The original remains on the memory card, and a copy is created on your computer.
    ::分享照片的一种方式是将照片下载到计算机中,然后复制到便携式闪存驱动器中。当您将照片从相机下载到计算机中时,您实际上正在将照片从一个地方复制到另一个地方。存储卡上的原始遗迹,并在您的计算机上创建了副本。

    Some digital cameras connect directly to a computer with a USB cable. Others are placed in a camera dock that stays connected to the computer with a USB cable. More often, though, you’ll use a memory card reader. A memory card reader is a small device which connects to the computer with a USB cable. The card reader has slots which fit one or more types of memory cards. When you insert a memory card in the card reader slot, the computer can access the files on the memory card. The card appears as another drive on the computer desktop (Macintosh) or My Computer/Computer (Windows). Double click on the drive icon to open it. The image files will be in a folder called DCIM. When you open this folder, you can copy image files onto your computer just as you would copy any other files. This is great for backing up important images or organizing them into collections.
    ::一些数字相机直接连接到带有USB电缆的计算机。 其它的则放在一个与USB电缆的计算机连接的相机码头。 不过, 更经常地, 您会使用存储卡阅读器。 记忆卡阅读器是一个小设备, 与USB电缆连接到计算机。 读卡器有适合一种或多种记忆卡的空格。 当您在读卡机的空格中插入存储卡时, 计算机可以访问存储卡上的文件。 该卡作为另一个驱动器出现在计算机桌面( Macinthosh) 或 My Cicopic/Computer (Windows) 上。 双击驱动器图标以打开它。 图像文件将放在一个名为 DCIM 的文件夹中。 当您打开此文件夹时, 您可以将图像文件复制到您的计算机中。 这对支持重要图像或将它们组织成收藏很有帮助 。

    SD card in a card reader

    Many computers now come with built-in memory card readers, so you don't have to connect an external one.
    ::许多电脑现在都有内置的记忆卡阅读器, 所以你不必连接外部的电脑。

    Some digital cameras come with software for downloading and organizing images. There are also programs available like iPhoto (Mac) or Picasa (Mac and Win).
    ::有些数码相机带有下载和组织图像的软件。 还有iPhoto(Mac)或Picasa(Mac和Win)等程序。

    Another way to share your photos is through social media. Smart phones, and even some new digital cameras, connect to the Internet via WiFi. With these devices, you can upload photos directly to social media sites like Facebook or Google+. 
    ::分享照片的另一种方式是通过社交媒体。智能手机,甚至一些新的数码相机,通过WiFi接入互联网。有了这些设备,你可以直接将照片上传到Facebook或Google+等社交媒体网站。

    However you download or share your photos, as you go through this course, you'll need to be able to show them to your teacher. You'll also need to use them in the course final project - Your Digital Portfolio.
    ::无论你下载或分享你的照片, 当你经过这个课程时, 您需要能够展示给老师。 您也需要在课程的最后项目中使用这些照片—— 您的数字组合 。
