在美國看著7月4日的國慶煙火，一直是一個長期存在的家庭傳統。但是，如果想用智慧型手機攝影功能的自動拍攝裝置，來捕捉演火在空中美麗暫影是困難的。所以，你如果想要留下煙火照片，可以試試以下這些簡單的技巧。
1、使用三腳架
當你拍煙火時，夜晚光線不足，所以手機的鏡頭需要保持快門的長時間曝光。手持容易振動，導致影像模糊，因此使用三腳架，可以確保有影像清晰。Joby’s GripTight Gorillapod三腳架，可以環繞樹木和電線桿或在地面上站起來，是個不錯的選擇，適合大多數智慧型手機。價格：$ 29.95在joby.com或亞馬遜有賣。
2、使用「風景 」模式
相機通常會自動找尋可聚焦的畫面。但在面對黑暗無光亮的天空時，相機就不知道該怎麼辦了。然而，在「風景」模式下，把你的相機預置聚焦到無窮大和縮小鏡頭開口(增加景深)，保持近及遠的重點對象。
當你自行操作一般相機，你會想查看看「煙火」模式。而大多數的傻瓜相機會有“SCN”或“Scene場景”的按鈕，否則，你可以在“Menu選單”按鈕中找到「煙火」模式。當你把你的相機設定在“Scene場景”模式中，可用的模式列表會出現在屏幕上，請選擇一個看起來像噴射的煙火和或叫「煙火」選擇鍵，你可以查詢我們的數位相機購買指南(http://www.techlicious.com/guide/digital-camera-buying-guide-2013/)。
3、關閉閃光燈
讓你的智慧型手機的相機模式知道只需要一種光源拍照。這是很重要的，因為這樣相機才會保持快門打開足夠長的時間來捕捉煙火。
4、調低ISO值
高的ISO值會照亮所有像片畫面的環境細節，反而無法凸顯煙火。雖然，煙火本身相當明亮，但是，為了避免曝光過度和細節噪音太多，請將你的相機ISO值，從「Auto自動」更改為ISO 100或甚至更低。 ISO值設置通常在「Menu主選單」中可找到，需要把你的相機在程序模式下更改設置。

Watching the July 4th fireworks has been a long-standing familytradition. But, capturing the beautiful aerial displays can be hard if youstick with the auto settings on your smartphone. So, try these simple tricksfor fireworks photos you’ll want to keep.
1. Use a tripod
When you take picture of fireworks, your phone’s camera needs tohold the shutter open long enough to “see” the fireworks. The longer theshutter is open, the more susceptible your photo is to motion blur. So use atripod to make sure there’s no movement. Joby’s GripTight Gorillapod, which canwrap around trees and poles or stand up on the ground, is a great option thatfits most smartphones. Price: $29.95 on joby.comor Amazon
2. Use the “landscape” mode
Your camera automatically tries to find an object on which tofocus. And when presented with a black featureless sky, the camera doesn’t knowwhat to do. By putting your camera in “landscape” mode, you’ll be presettingthe focus to infinity and narrowing the lens opening, which keeps both near andfar objects in focus.
If you have access to a camera, you’ll want to look for“fireworks” mode. Most point-and-shoot cameras have a button or dial with “SCN”or “Scene” on it. Otherwise you’ll find it under the “menu” button. When youput your camera in scene mode, a list of the available modes will pop up onscreen. Select the one that looks like a spray of fireworks and/or says“fireworks.” Check out our picks in our DigitalCamera Buying Guide.
3. Turn off the flash
Turning your flash off will let your phone’s camera know thatit only has available light to take a picture. This isimportant because the camera will then keep the shutter open long enoughto capture the fireworks. The flash button is usually a separate button on themain camera app screen.
4. Turn down the ISO
High ISO will crank up the sensitivity of the camera so it can seedetails in the dark. However, the fireworks themselves are quite bright. So, toavoid overexposure and reduce film noise, take your camera out of Auto ISO andchange the setting to ISO 100 or even lower. The ISO setting is usually foundunder the main menu. You may have to put your camera in program mode to changethis setting.
