一周多前在網(wǎng)上搜到的一篇技術(shù)文檔，覺得還不錯。雖然平時用ps時大概也能知道哪種保存方式更合適，但基本停留在經(jīng)驗基礎(chǔ)上，而這篇文章對另存為和另存為網(wǎng)頁格式有詳細的文件數(shù)據(jù)分析，覺得比較有做參考資料的價值，所以決定翻譯一下。翻譯之前覺得很短一篇，不過真正翻時感覺長了五倍都不止，一看全篇英文就犯困，翻翻停停拖了很久才算差不多了。我用英文版ps，很多術(shù)語不清楚中文怎么說，外加英語爛，所以可能翻譯有些問題，望大家指正。--tea00

Photoshop Save As vs Save For Web
One of the more confusing options in Photoshop CS2 arises when it comes time to save your edited image. There are two methods to save your photo: using the Save As dialog box or using the Save For Web dialog box. This article answers the question: what are the differences between save for web and save as, and when should I use Save for Web?
Photoshop offers two options to save your image after editing:
- File -> Save As ...
- File -> Save For Web ...
Both of these menu otpions create an output JPEG file from your working image, but they differ in both the available options, flexibility and representation of JPEG compression quality.
Photoshop另存為和另存為網(wǎng)頁格式
Photoshop cs2中最易混淆的選項之一是在保存編輯過的圖片時，有兩種保存圖片的方式——另存和另存為網(wǎng)頁格式。本篇文章將解答另存和另存為網(wǎng)頁格式有何區(qū)別，以及何時應(yīng)該選擇保存為web格式。
Photoshop提供了兩種保存編輯過的圖片的方式
- 文件->另存為
- 文件->另存為網(wǎng)頁格式
兩種保存方式都可以輸出jpeg格式圖片，但兩種方式在jpeg壓縮質(zhì)量的選項、靈活度和表現(xiàn)上有所區(qū)別。
Quick Choice
If you plan to...【You should use】
Create images for your website, or optimize the file as small as possible【Save For Web 】
Share images with others, and you want viewers knowing shot time/date, etc. 【Save As 】
Share images with others, and you do not want others knowing shot time/date, etc. For example, stock photos, or concerns over privacy 【Save For Web】
Convert your image to a given file size, or you want interactive feedback on quality settings 【Save For Web】
... for all other cases【Save As】
快速選擇
如果你想要…【那么選擇的保存方式是】
創(chuàng)建網(wǎng)頁使用的圖像，或者想盡可能的優(yōu)化圖像文件的體積【另存為網(wǎng)頁格式】
和他人分享圖片，而且你希望別人知道你拍攝照片的時間日期等【另存為】
和他人分享圖片，但你不希望別人知道你拍攝照片的時間日期等，比如用于圖片庫，或是需要保護隱私【另存為網(wǎng)頁格式】
把圖像文件壓縮到指定的大小，或者你想要在設(shè)定圖像質(zhì)量時能有交互的反饋【另存為網(wǎng)頁格式】
其它情況【另存為】
Photoshop Save As
The Save As dialog includes a very large number of output file formats, as it is the standard method by which users will generate their final image files. As this output method is not optimized towards transmission over a low data-rate medium (such as the internet), additional information is encoded into the resulting image at the cost of increased file size. As shown below, this additional data may consume approximately 40KB.
One of the main reason that photographers choose Save As instead of Save for Web when sharing photos is so that the EXIF metadata (which includes camera information and shot details) can be displayed to other interested viewers. Most photo sharing sites (such as pbase) automatically extract this EXIF information, for the benefit of other photographers. However, considering that it also includes the time and date of the original shot, it may have privacy implications.
Photoshop 另存為
另存為是用戶輸出最終圖像文件的標準方式，因此對話框中有輸出多種文件格式的選擇。這種保存方式?jīng)]有為低速數(shù)據(jù)傳輸方式（例如互聯(lián)網(wǎng)）優(yōu)化文件，保存的圖像文件中包含了附加信息，因此文件體積較大。如后面所示，這些附加數(shù)據(jù)的體積可能接近40kb。
攝影者通常選擇另存為而不是另存為網(wǎng)頁格式的一個主要的原因是，在分享照片時，觀看者能夠查看到圖片的Exif信息（包括相機和拍攝信息）。大部分照片分享網(wǎng)站（例如pbase）都能自動提取Exif信息，以方便其它攝影者查看。盡管如此，Exif信息包含著照片拍攝的時間日期信息，所以可能涉及隱私。
16-bit Mode
As Save As does not support for 16-bit images, it may be necessary to convert to 8-bit first, save and then undo the color depth conversion step if you plan to continue working on the file. You can convert to 8 bit RGB by selecting Image -> Mode -> 8-bits/channel. Save for Web automatically converts the color depth for you.
16位模式
由于”另存為”不支持保存16位模式的圖像，所以有必要先轉(zhuǎn)換成8位模式，保存。如果你要繼續(xù)處理圖片的話，就撤銷上一步顏色位深的設(shè)置。把圖像轉(zhuǎn)為8位RGB圖像的方式是菜單上的圖像->模式->8位/通道。另存為網(wǎng)頁格式會自動為你轉(zhuǎn)換顏色位深。
