Bringing the blur back into focus...
還原模糊為清晰
Isn't it annoying when you take a set of photos, and many of them come back blurred? It's one of the most common problems photographers have, but one of the hardest to correct after the photograph has been taken!
當你拍了很多照片而其中的很多卻是模糊的，這不是很讓你苦惱麼？這對攝影師來說是一個最普遍的問題，但是最困難的是如何修復這些拍攝模糊的照片。
This tutorial will show you how to repair photo blur, and how to avoid it in the future.
這篇教學將向你展示如何修復模糊照片以及在將來如何避免拍出這樣的照片。
The Basic Principle
基本原則
If you've used Photoshop or Photoshop Elements for a while now, you may have noticed two terms that walk hand in hand. 'Blurring' and 'Sharpening'.
如果你現在使用的是Photoshop 或Photoshop Elements，你會注意到兩個項目在一起——「模糊」和「銳利化」。
Basically, sharpening an image is the opposite of blurring it. Photoshop Elements provides many different ways to sharpen an image.
一般說來，銳利化影像是和模糊影像相反的過程。 Photoshop Elements 提供了許多不同的方法來銳利化一張圖片。
To start with there's the 'Sharpen Tool', found near the bottom of your tool palette. This allows you to sharpen just a certain area of a picture, using an appropriate brush shape and size.
你可以在工具列底部找到“銳利化工具”，它可以讓你使用適當的筆刷形狀和大小在一定範圍內銳化一張圖像。
If you're sharpening the whole image, you can use the filters in the 'Sharpen' category under the 'Filter' menu. These include 'Sharpen', 'Sharpen More', and 'Sharpen Edges'.
如果你要銳利化整張影像，你可以使用濾鏡選單中的濾鏡庫中的濾鏡，它們包括「銳利化」、「進一步銳利化」和「銳利化邊緣」。
Additionally to all of that, if you like to correct photos in 'Quick Fix' mode, there is a sharpen slider available in that section for you to use.
另外，如果你想在快速修復模式中修復影像，只有銳利滑桿供你使用。
A 'Quick' Example
快速修復的例子
Shown further down is a portion of a photograph I took which exhibited minor blur. This is a correctable level of blur, and so I opened the photo in Photoshop Elements, and switched into 'Quick Fix' mode, owning the 隨ton shode
下面顯示的是我拍的有輕微模糊的部分照片（此句翻譯不准確，不知道如何翻），這在模糊的修復的範圍內，所以我在Photoshop Elements中打開照片，然後切換至快速修復模式，使用如下圖所示的按鈕：
I always like to see the before and after picture in quick fix mode, and so I changed my view accordingly.
通常，我會觀察在快速模式中處理前和處理後圖片，因此我適時改變我的看法。
To do this, use the drop down box in the bottom left hand corner, and select 'Before and After (Portrait)', as shown below:
要做到這一點，請使用左手邊的下拉式選單，選擇Before and After (Portrait)，如下圖所示：
The 'Sharpen' slider is the furthest one down on the right hand side by default. By dragging it around two thirds of the way along, I was able to reduce the blurring effect on my photo. Shown below is the reduce the blurring effect on my photo. Shown below is the 鑑:
銳利化滑桿在預設的情況下在最右邊，透過拖曳滑桿至2/3處，通常我就能夠減少模糊對我照片的影響，下圖就是銳利化處理前和處理後：
Over-Sharpening
過度銳化
Unfortunately, sharpening is a rather in-exact art, and carries a danger with it. Because of the way it works, it is all-too-easy to 'over-sharpen' an image, causing very unattractive results.
不幸的是，銳化是一個相對不確切的藝術，同時它也帶來一定的危險，因為它的工作方式，很容易對圖像過度銳化，導致相當不好的效果。 This is especially common when using the sharpen tool on a high strength setting. Below is shown an image which demonstrates the effect of over-sharpening:
這在使用高強度設定銳利化工具時尤其常見，下圖顯示了過度銳利化的效果：
To avoid over-sharpening, use the sharpen tools on low intensities, and only where they are needed.
為了避免過度銳利化，使用銳利化工具時設定低強度，而且只在需要地方使用。
Severe Blurring
劇烈的模糊
In cases where images are extremely blurred, it is often impossible to repair them effectively.
如果照片劇烈模糊，那麼通常不會有有效的方式修復。
Below is shown an image, with some close-up sections, which is blurred to the point of no return:
下圖顯示，在相近的區域，模糊並沒有減輕。
There is very little you can do to correct images like this, but there is a lot you can do to avoid them!
對這樣的照片你幾乎不能修復他們，但是你可以避免拍出這樣的照片。
Camera Shake
相機震動
The photo above was taken from a moving vehicle. To avoid blurring, photos should always be taken when the camera is stationary.
上面的照片是在行駛中的車上拍攝的。為避免模糊，拍攝時應保持相機靜止。
If you find (like me!) that your hands shake when you are taking photos, find。
當你發現拍照是你的手在抖動找一些能固定相機的東西，理想的應該是三腳架，但是沒有三腳架可用時，尋找牆壁或其他表面。 If no surface is available, try leaning up again something, or putting your elbows by your side, to steady your arms and reduce camera-shake.
如果沒有合適的表面，可以試著斜靠到某個東西上，或者將你的胳膊肘靠在你的身體上，還或者穩定你的手臂以減少相機抖動。
Shutter Speed
快門速度
Another way to reduce blurring is to increase the shutter speed of your camera. If your camera allows you to manually set the shutter speed, it is useful to remember that on high shutter speeds, urring is usally to remember that on high shutter speeds, urring is usally urring is usally .
另一個避免模糊的方法是提高你相機快門的速度，如果你的相機支援手動設定快門速度，記住提高快門速度可以極大的減少模糊。
Unfortunately the reverse is also true. Using slow shutter speeds, perhaps to compensate for bad light, blur is dramatically increased. Ensure that the camera is perfectly still on low shutter speeds.
不幸的是相反的也是真的（此句翻譯不准確，不知道如何翻），使用慢快門速度，或許能夠彌補光線不足，但是模糊隨之劇烈增大，保證相機是完美的仍是低快門速度。
Bad Light
光線不足
Apart from shutter speed, photos are usually more prone to blurring in bad light anyway. If you are taking photos inside, ensure you use a flash if light is fading. When outside, the best tactic is oncegain a pererafly stillic is on tactic is oncegain a.
除了快門速度照片模糊有時也是因為光線不足導致的，如果你在室內拍攝，如果光線不足確保打開閃光燈，在室外時，最好的策略仍取決於相機（此句翻譯不准確，不知道如何翻） 。
If in Doubt...
迷惑中…
If you are struggling to take a particular image, the only other advice I can offer is to take lots of pictures! On a digital camera there can be a reasonably large variation between repeat shots.

如果你努力想拍出特別的相片，我給你的唯一的建議就是多拍！在數位相機上你可以重複的拍攝，你拍的越多，你得到最好的照片的幾率越大！

As you can see, especially around the text on the sign, the blur has been reduced by sharpening the image.
如你所見，尤其在標誌上的文字部分，影像的模糊被銳化了。
