Most people have the basics of throwing a movie night down: you get a movie, you get snacks, you get comfortable, and boom, you’re done. When it comes to throwing a movie party in the backyard, however, things get a little trickier. Read on as we show you how to do it stress free.
大多数人都有丢下电影之夜的基本知识：看电影，吃零食，舒适，繁荣就完成了。 但是，当涉及到在后院举行电影派对时，事情会变得有些棘手。 请继续阅读，我们会向您展示如何做到无压力。
Sure, you can watch your movie indoors. There will be no bugs, no waiting for dusk, and likely zero prep work, but there also won’t be that magic of projector light, the glow of the screen against the twilight sky, or the sheer excitement kids (and adults alike for that matter) get when watching a movie outside in the fresh air.
当然，您可以在室内观看电影。 不会有虫子，没有等待黄昏，也没有可能进行零准备工作，但也不会有投影仪灯光的魔力，暮光之城的屏幕发光或纯粹的兴奋孩子们(大人都喜欢问题)在新鲜空气中看电影时得到。
That said, hosting an outdoor movie night is significantly more challenging (at least the first time you do so) than simply popping in a DVD for the kids and leaving them in the living room. Further, there’s a bit more that goes into a successful movie night than your average article implies. As veterans of backyard movie madness, we’re more than happy to walk you through the details big and small to help ensure you have the perfect movie night experience.
也就是说，举办一场户外电影之夜(至少是第一次这样做)要比仅仅为孩子们弹出DVD并留在客厅里更具挑战性。 此外，成功的电影之夜还有比您的平均文章所暗示的要多的东西。 作为后院电影疯狂的退伍军人，我们非常乐意向您介绍各种细节，以确保您拥有完美的电影之夜体验。
投影机 (The Projector)
You could host a movie night outside by hauling a big screen HDTV out the back door and setting it up on the patio, but we’ll be frank with you: it simply doesn’t have the same magic feeling. Sure it’s novel and a nice change of pace (and the kids might be entertained by the new viewing arrangement) but to really capture the essence of backyard movie magic, to reclaim the spirit of the drive-in movie theater and the open air, you need that bright-shining-point-of-light-in-the-darkness effect that only a project can provide.
您可以通过从后门拉大屏幕高清电视并将其安装在露台上来在外面举办电影之夜，但是我们会坦率地说：这简直就是不一样的魔幻感觉。 当然，它是新颖的，而且步调也很好(新的观看安排可能会让孩子们开心)，但要真正抓住后院电影魔术的精髓，重拾露天电影院和露天的精神，需要只有项目才能提供的那种在黑暗中明亮发光的效果。
Although projectors are certainly pricey investments, there’s good news: you don’t need a top of the line projector for your backyard movie night. Although you can spend $1000+ on a projector (or haul your nice indoor projector from your movie room outside) you don’t need to spend that much. You can grab a smaller, cheaper one on Amazon, or–if you’re really thrifty–find an old one on Craigslist. (Spring is a good time to search for used models, as many offices and schools are clearing theirs out.)
尽管放映机无疑是一笔昂贵的投资，但有一个好消息：您无需在后院电影之夜使用顶级的放映机。 尽管您可以花1000美元以上购买一台投影机(或从外面的电影室拖曳漂亮的室内投影机)，但您并不需要花费那么多。 您可以在亚马逊上买到一个更小，更便宜的产品，或者，如果您真的很节俭，可以在Craigslist上找到一个旧的产品。 (Spring是寻找二手模型的好时机，因为许多办公室和学校都在清理它们。)
When considering a projector for use in the backyard, you should consider the following factors.
考虑在后院使用投影机时，应考虑以下因素。
流明 (Lumens)
The lumen rating of a projector is indicative of how much light is can output. The more light a projector can put out, the sooner you can start your movie, and the better it can cut through ambient light (like light from street lamps, light from the tiki torches on your patio, etc.)
投影仪的流明等级指示可以输出多少光。 投影机发出的光越多，您越早开始播放电影，越能穿透周围的光(例如路灯发出的光，露台上的提基火炬发出的光等)。
At minimum, you want at least 2,000 lumens. Every step up from there is a huge boost and as you creep closer to 3,000+ lumens you really increase the power of the projector and it becomes possible to start the movie shortly after sunset instead of waiting another 30-40 minutes for it to get much darker.
至少需要至少2000流明。 从那里迈出的每一步都有巨大的提升，并且当您逐渐接近3,000+流明时，您确实增加了投影机的功能，并且有可能在日落之后不久开始播放电影，而无需等待30-40分钟来获得更多更暗。
多种输入 (Diverse Inputs)
It’s no fun if the thing you want to plug into the project can’t be plugged into the projector because it lacks the correct ports. You can always correct for those kind of problems by hooking up a full blown audio-visual receiver to the setup but that adds expense, bulk, and complexity.
如果您要插入项目的东西由于缺少正确的端口而无法插入投影机，这没什么好玩的。 您始终可以通过将功能完备的视听接收机连接到设备上来纠正此类问题，但这会增加费用，体积和复杂性。
It’s oft overlooked, but when you’re looking for a project make sure it has the kind of connection input on it that works with the device you want to use (e.g. your laptop, a Blu-ray player, etc.). If they don’t match (say, a new laptop with HDMI and your old projector with VGA), make sure you get an adapter so everything can fit together.
它经常被忽略，但是当您寻找项目时，请确保其上具有与您要使用的设备(例如，笔记本电脑，蓝光播放器等)兼容的连接输入。 如果它们不匹配(例如，一台带有HDMI的新笔记本电脑和一台带VGA的旧投影仪)，请确保您有一个适配器，以便所有部件都能放在一起。
梯形失真校正和镜头移位 (Keystone and Lens Shift)
Lower-end projectors have electronic keystoning (you can adjust the image thrown by the projector to make up for the angle of the projector in relationship to the screen) and more expensive cinema-style projectors have physical controls which allow you to shift the actual lens to correct for image distortion.
低端投影仪具有电子梯形失真(您可以调整投影仪投射的图像以补偿投影仪相对于屏幕的角度)，而价格更高的电影院式投影仪具有物理控件，可让您移动实际镜头校正图像失真。
These features are very important for outdoor projection as you’ll likely be putting the projector on a card table or the like wherever you can fit in your outdoor setup and you’ll need to immediately and on the fly adjust the image to fit the projection surface.
这些功能对于室外投影非常重要，因为您可能会将投影机放在户外安装中适合的任何地方，并且需要立即快速调整图像以适合投影表面。
最大尺寸和投掷距离 (Maximum Size & Throw Distance)
One of the most fun aspects of outdoor movie viewing is that you can go big without much expense. An HDTV with a 144″ diagonal could cost you $100,000 but a projection setup at the same size and resolution could run you less than a $1000.
户外电影观看中最有趣的方面之一就是您可以花很多钱就可以变大。 带有144英寸对角线的HDTV可能要花费您$ 100,000，但以相同尺寸和分辨率进行投影设置可能要花费不到$ 1000。
The first consideration, and one to keep in mind when making or buying a screen, is how big of an image your projector and project and how far away it needs to be to accomplish that. The specifics of those factors (maximum screen size and the required “throw distance”) are a function of the particular model and how it’s bulb and lens are arranged. To that end, we recommend studying your space and then consulting the manufacturer specifications. If you want to project a 200″ image, for example, but the projector you plan on using needs 30 feet between the projector and the screen to accomplish that, then you’d better make sure you’ve got the backyard that will house such an arrangement.
首先要考虑的问题是制作或购买屏幕时要牢记的一点，即投影机和投影机要投影多大的图像以及完成该操作需要多远。 这些因素的细节(最大屏幕尺寸和所需的“投射距离”)取决于特定型 以及灯泡和镜头的布置方式。 为此，我们建议您研究您的空间，然后咨询制造商规格。 例如，如果您要投影200英寸的图像，但是您计划使用的投影仪需要在投影仪和屏幕之间30英尺的距离才能完成此操作，那么最好确保您拥有可容纳此类投影仪的后院一项安排。
Unlike indoor installations, it’s pretty easy to move the pieces of an outdoor projection setup around (we’ve adjusted the spacing of our projector and screen by just picking them up and scooting them around more than a few times), but it’s still handy to use a calculator to figure things out ahead of time. To that end, we recommend the throw distance calculator over at Projector Central. You can see, in the screenshot above, how we used it to calculate the optimum distance to get the maximum size. You can also use the calculator to figure out the perfect spacing for the size screen you’ll be using.
与室内安装不同，很容易移动室外投影设置的各个部分(我们已经将投影机和屏幕的间距进行了调整，只需捡起它们并在其周围进行多次滑动即可)，但仍然很方便使用计算器提前解决问题。 为此，我们建议在Projector Central投影距离计算器。 您可以在上面的屏幕截图中看到我们如何使用它来计算最佳距离以获得最大尺寸。 您也可以使用计算器找出将要使用的尺寸屏幕的理想间距。
解析度 (Resolution)
Most people would expect to see resolution at the top of the list–after all, resolution is super important to picture quality, rightThe reality is that resolution isn’t as important as you think. In your houseSure. On an HDTV you’re sitting relatively close toSure. But in these cases, you’re using your projector or HDTV under optimum conditions, where the quality of the image is going to attract close scrutiny.
大多数人希望将分辨率放在列表的首位，毕竟分辨率对于图像质量至关重要。 现实情况是，分辨率并不像您想象的那么重要。 在你的房子当然。 在高清电视上，您所坐的位置相对较近当然。 但是在这些情况下，您是在最佳条件下使用投影机或HDTV，在这种情况下，图像质量将受到严格审查。
During a backyard movie night, however, you aren’t viewing a movie under optimum viewing conditions. You’re viewing the movie under optimum fun conditions. The last light of sunset will impart a haze. There will be ambient light of a greater or lesser degree that may or may not pollute the purity of the projected image. The screen might have wrinkles in it. There might be kids running around casting shadows everywhere.
但是，在后院电影之夜，您无法在最佳观看条件下观看电影。 您正在最佳娱乐条件下观看电影。 夕阳的最后一缕会散发出薄雾。 将存在或多或少程度的环境光，该环境光可能会或可能不会污染投影图像的纯度。 屏幕上可能有皱纹。 可能到处都有孩子到处乱投阴影。
Under those kind of conditions, it matters more than the image is bright and crisp (because you have lots of lumens and have adjusted the focus/keystone/shift correctly) than it is the highest resolution available.
在这种情况下，重要的是图像的亮度和清晰度(因为您有很多流明并且已正确调整了焦点/梯形失真/偏移)，而不是最高分辨率。
If you have a 1080p projector with good light output then by all means use it. But don’t write off a business-class projector that only has VGA or XVGA resolution just because it isn’t capable of “HD” output. Even a business projector is still capable of outputting at a higher rate than old broadcast TV and DVDs and it still looks nice.
如果您的1080p投影机具有良好的光输出，则一定要使用它。 但是不要因为没有“高清”输出能力而只注销具有VGA或XVGA分辨率的商务级投影仪。 即使是商务投影仪，仍然能够以比旧的广播电视和DVD高的速率输出，并且看起来仍然不错。
长宽比 (Aspect Ratio)
Again, like resolution, aspect ratio is something to consider but not mission critical. Ideally, your projector will output at a ratio of 16:9, which is the widescreen format favored by the vast majority of movie releases. This way, your output matches up perfectly with a 16:9 screen and there is no light bleed or masking required.
同样，像分辨率一样，长宽比是要考虑的，但不是关键任务。 理想情况下，投影机将以16：9的比例输出，这是绝大多数电影发行都喜欢的宽屏格式。 这样，您的输出就可以与16：9屏幕完美匹配，并且不需要漏光或遮罩。
Your cinema-class projector will do this, no questions asked, because that’s what it was build to do: show movies. Your business class projector likely will not do native wide screen projection but it will provide a digital mask for 16:9 projection. The trade off is that you’ll have “light bleed” at the top and the bottom of the screen because the business-class projector will mask the area simply by projecting black and not actually physically masking the space off.
毫无疑问，您的电影级投影机将执行此操作，因为这就是它的构建目的：显示电影。 您的商务舱投影仪可能不会进行原生的宽屏投影，但会为16：9投影提供数字遮罩。 权衡取舍的是，您将在屏幕的顶部和底部出现“光斑”，因为商务级投影仪将仅通过投射黑色来遮盖该区域，而实际上并未实际遮盖该空间。
While that’s less than ideal, it’s also not a deal breaker. Most people won’t even notice the light bleed, especially if you’re using a widescreen sized screen and the light bleed just falls into the darkness behind the screen.
尽管这不理想，但这也不是交易突破。 大多数人甚至都不会注意到光的渗出，特别是如果您使用的是宽屏尺寸的屏幕，而光渗入只是掉在屏幕后面的黑暗中。
差异重要吗(Do the Differences Matterspan style=”font-weight: bold;”>)
With all those factors in mind, let’s look at some real world examples to show you how certain factors matter (or don’t).
考虑到所有这些因素，让我们看一些真实的例子，向您展示某些因素的重要性(或无关紧要)。
We’ve hosted many outdoor movie nights over the years and just leading up to writing this article we conducted a wide range of tests and scrutinized the results. We conducted these tests using two very different digital projectors: the Epson HC600 and the Epson HC3000. In their respective tiers, they’re both great projectors, but they’re certainly different.
The HC600 ($360) is one of Epson’s entry-level cinema projectors. It’s bright (3000 lumens) but it has a low resolution (only 800×600), and it offers no manual lens shift (but has digital keystoning). Although the HC600 is a perfectly solid (and very bright) projector in its price range, it has more in common with projectors you’d find in board rooms and classrooms than high-end home theaters.
HC600(360美元)是爱普生的入门级电影放映机之一。 它明亮(3000流明)，但分辨率低(仅800×600)，并且不提供手动镜头移位(但具有数字梯形失真)。 尽管HC600在其价格范围内是一款非常坚固(非常明亮)的投影仪，但与高端家庭影院相比，它与会议室和教室中的投影仪有更多的共同点。
The HC3000 ($1150) is a cinema-class projector designed for home theater use. It’s still pretty bright (2300 lumens) and we had no problems with a dim image while using it, it has true 1080 resolution in native 16:9 projection, and has very smooth and easy to use manual lens shift adjustment knobs.
HC3000(1150美元)是专为家庭影院使用而设计的电影级投影仪。 它仍然非常明亮(2300流明)，使用它时我们对暗淡的图像没有任何问题，它在原始的16：9投影中具有真正的1080分辨率，并且具有非常平滑且易于使用的手动镜头移位调节旋钮。
As you can imagine, the HC3000 projector did, in fact, look better. If you focused even a modest amount of scrutiny on the images in comparison the Cinema 3000 unit was the clear winner (and at a cost three times higher, it should be).
可以想象，HC3000投影仪实际上看起来更好。 相比之下，如果您仅对图像进行少量检查，Cinema 3000无疑是赢家(而且成本应该高出三倍)。
While a discriminating adult who is really analyzing image quality will definitely see the difference, not one kid during our backyard movie night spree was like “Wait a minute! Who switched out the 1080p projector for a mere VGA projectorI want my money back!” As long as the projector was bright, the image was properly focused, and the movie was rolling, they were all completely enraptured by the magic of the screen.
虽然确实会分析图像质量的有区别的成年人肯定会看到差异，但是在我们后院电影之夜狂欢中没有一个孩子会像“等一下！ 谁将1080p投影仪换成了纯粹的VGA投影仪我想要回我的钱！” 只要放映机是明亮的，图像就可以正确聚焦，电影就可以滚动，它们全都被屏幕的魔力迷住了。
If you can afford the HC3000, it’s a beautiful projector that provides a beautiful image (and you’ll certainly want to put a projector mount in your house and use it all the time). If you can’t afford a $1,000+ projector, don’t write off hosting a movie night. Projectors like the HC600 are more affordable, and if a new projector is totally outside of your budget you can almost always find used business-class projectors on Craigslist as companies, schools, and other institutions churn through their stock. If you’re willing to spend $50-100 on a replacement bulb, you can almost always find a business-class projector dirt cheap.
如果您买得起HC3000，则它是一台可以提供美丽图像的漂亮投影机(并且您肯定会希望将投影机支架放到家里并一直使用)。 如果您买不起一台1,000美元以上的投影机，请不要取消举办电影之夜的费用。 像HC600这类的投影仪价格更便宜，而且如果一台新的投影仪完全超出您的预算，您几乎总是可以在Craigslist上找到二手的商务级投影仪，因为公司，学校和其他机构都在竭尽所能。 如果您愿意在更换灯泡上花费50-100美元，则几乎总是可以找到便宜的商务级投影机。
In short: by all means get a nice cinema-class projector for your backyard movie (and home) experience if you can, but don’t let a high price tag stand in your way as there are very economical options available.
简而言之：如果可以的话，一定要为您的后院电影(和家庭)体验提供一台不错的电影院级放映机，但不要因为高昂的价格选择而阻碍高昂的价格。
媒体播放器 (The Media Player)
What will play your moviesA disc-based system like a DVD or Blu-ray playerYour laptopA dedicated media player like an Apple TV or Amazon Fire TVThe media player you select is, paradoxically, almost entirely unimportant and really important for two different reasons.
什么会播放您的电影DVD或Blu-ray播放器等基于光盘的系统您的笔记本电脑专用的媒体播放器，例如Apple TV或Amazon Fire TV矛盾的是，您选择的媒体播放器几乎完全不重要，并且由于两个不同的原因而非常重要。
On one hand, it’s almost unimportant as long as it plays what you want: once the movie is running smoothly, nobody is going to care if it’s fed into the projector from a disc, a flash drive, or streamed from your home network as long as it looks nice.
一方面，只要能播放所需的内容就几乎不重要：一旦电影运行顺利，就不会有人在乎电影是从光盘，闪存驱动器馈入投影机，还是从家庭 络流式传输。看起来不错
On the other hand, the media player you select (because of the available video inputs/outputs) can either make setting up your outdoor theater easier or harder (often adding a significant amount of complexity to wiring up your sound system).
另一方面，您选择的媒体播放器(由于可用的视频输入/输出)可以使室外影院的安装更加容易或困难(通常会增加连接音响系统的复杂性)。
If you plan on using media you have stored locally–purchased on iTunes, ripped from your DVD collection, streamed what Netflix, or whatever–a laptop is a great choice, as you can play a diverse range of stuff on it, it typically has an HDMI and/or VGA output for the projector, and it has a headphone jack ready to pipe into somewhere.
如果计划使用本地存储的媒体(在iTunes上购买，从DVD收藏中抓取，流式处理Netflix或其他内容)，则笔记本电脑是个不错的选择，因为您可以在笔记本电脑上播放各种内容，投影仪的HDMI和/或VGA输出，并且具有准备好插入某处的耳机插Kong。
Further, you can run all sorts of apps like Kodi Media Center and VLC, you can easily do slideshows or pull up YouTube videos, and so on. While we do like the geek cred aspect of setting up a little Raspberry Pi media box and using that, you really can’t beat a laptop for diversity (and it has a built-in screen for the projector operator to use which other options, like an Apple TV, do not).
此外，您可以运行各种应用程序，例如Kodi Media Center和VLC，还可以轻松地进行幻灯片放映或提取YouTube视频，等等。 尽管我们确实喜欢设置一个小小的Raspberry Pi媒体盒并使用它的怪胎，但您确实无法击败笔记本电脑的多样性(它具有内置屏幕，供投影仪操作员使用其他选项，就像Apple TV一样)。
音响系统 (The Sound System)
“The sound systemWhat about the screen!” you say. Don’t worry, we’ll get to the screen. The reality is that the projector and the screen aren’t as finicky and complicated as the sound system. The projector comes down to “go big, go bright”, and you’d be amazed at the variety of things we can project on (we once hosted a Super Smash Bros. tournament that was projected onto a white garage door and it worked out just fine).
“音响系统屏幕呢！” 你说。 不用担心，我们将进入屏幕。 现实情况是，投影仪和屏幕并不像音响系统那样复杂而复杂。 投影仪降为“变大，变亮”，您会为我们可以进行的各种投影感到惊讶(我们曾经举办过一次《 Super Smash Bros.》比赛，投影到了一个白色的车库门上，结果正好)。
The sound system, on the other hand, requires a little more planning. While it’s easy enough to take a Blu-ray player and plug it into the HDMI port on a projector, where’s the soundThis is the element of the evening you need to spend the most time thinking about and planning for because, logistically, it’s the most complex. If the projection is a teensy bit washed out or the screen a little wrinkled, nobody will likely notice or care. If the sound system is too weak, muffled, or hard to understand, the audience will lose interest quickly.
另一方面，声音系统需要更多的计划。 将蓝光播放器轻松插入投影仪的HDMI端口虽然很容易，但是声音在哪里呢这是晚上您需要花费大量时间进行思考和计划的元素，因为从逻辑上讲，这是最复杂的。 如果投影被一点点冲洗掉或屏幕有点起皱，则没人会注意到或关心它。 如果声音系统太弱，低沉或难以理解，听众会很快失去兴趣。
Over the years we’ve experimented with many, many, different ways to run sound for our outdoor movie nights that range from hauling an entire AV receiver outside, running cable, and setting up 5.1 surround sound in the yard (which is no small undertaking, requires lots of wire, and we were worried about kids tripping on a wire or trashing a speaker the whole time) to using a single but powerful all-in-one speaker.
多年来，我们已经尝试了很多很多，不同的方法来为我们的户外电影之夜，从院子里拖整个AV接收器之外，运行线，并设置了5.1环绕声(这是个不小的任务范围运行声音，需要大量的电线，我们担心孩子们经常绊在电线上或浪费扬声器)以使用单个但功能强大的多合一扬声器。
Although we can attest to having watts upon watts of power setup with a dedicated subwoofer being awesome, we’re going to defer to the mindset we highlighted in the projector section: you aren’t going for perfect audio fidelity here, you’re going for the good-enough-for-fun fidelity. The less wiring, the less fussing, and the less worrying about the setup you have to do the better.
尽管我们可以用超重的低音炮来证明功率设置上有瓦特，但我们还是要遵循在投影仪部分突出显示的思维定式：在这里您并不需要完美的音频保真度，为了获得足够的乐趣。 接线越少，烦恼就越少，而您对设置的担心就越少，那就越好。
To that end, our current favorite arrangement is one that we find extremely convenient: we use a beefy Bluetooth speaker and pipe the sound wirelessly to the audience. If you’re a long-time reader you might recall the beefy tabletop Bluetooth speaker we used as a demo unit in our article The HTG Guide to Portable Bluetooth Speakers, the Nyne Bass. We pair the Nyne, which has a huge amount of sound and rich bass for its size, with a Bluetooth transmitter (the Avantree Priva, which we recommended in the article How to Add Bluetooth Headphones to Your HDTV) hooked to the headphone jack on our laptop.
为此，我们目前最喜欢的一种安排是我们发现非常方便的一种安排：我们使用功能强大的蓝牙扬声器，并将声音无线传递给听众。 如果您是一位长期阅读者，您可能会想起我们在《 HTG便携式蓝牙扬声器指南： Nyne Bass 》一文中用作演示单元的功能强大的台式蓝牙扬声器。 我们将Nyne(具有巨大的声音和丰富的低音)与挂钩在我们耳机插Kong上的Bluetooth发送器( Avantree Priva ，我们在文章“如何向HDTV添加Bluetooth耳机”中推荐的)配对。笔记本电脑。
Now, again, we recommend using what you have on hand to avoid a huge bill for your movie night. We happened to have a nice Bluetooth speaker and a transmitter on hand. If we didn’t have those items on hand, we would have used other things we had on hand (like a 20 foot phono-jack cable to the auxiliary input jack on an old boombox we keep out in our workshop). A $4 cable plus a $10 yard sale boombox could work just as well for you.
现在，再次，我们建议您使用手头上的东西，以避免在电影之夜花费巨额账单。 我们碰巧手边有一个漂亮的蓝牙扬声器和一个发射器。 如果手头没有这些物品，那我们将使用我们手头上的其他东西(例如，一条20英尺的耳机插Kong电缆连接到我们存放在车间中的旧音箱上的辅助输入插Kong)。 一条4美元的电缆加上一个10美元的院子里的音箱，可能对您同样有效。
屏幕 (The Screen)
It might seem strange to many readers that we’ve put the screen this far down in the list of considerations, but honestly compared to the logistics of selecting a projector, setting up some sort of media player, and getting the sound system linked in, the screen is truly (we promise!) almost an afterthought.
对于许多读者来说，我们将屏幕放到考虑的范围之内可能看起来很奇怪，但是老实说，与选择投影仪，安装某种媒体播放器和连接音响系统的后勤工作相比，屏幕确实(我们保证！)几乎是事后才想到的。
Outdoor projection is extremely forgiving when it comes to screen quality, as the brightness of the projector, the potential light pollution from street lamps and the like, as well as just the general excitement and activity of the evening generally smooth over any sort of imperfections (if they are even noticed at all).
当涉及到屏幕质量时，户外投影是非常宽容的，因为投影机的亮度，路灯等的潜在光污染以及夜晚的一般兴奋和活动通常会因各种瑕疵而变得平滑( (甚至根本没有注意到它们)。
When it comes to selecting an outdoor projection screen, your three questions should be, in this order: what is my budgethow big do I want itdo I want rear or front projectionAlthough we haven’t delved into it before this point, rear projection is a really handy tool to have in your backyard movie night toolkit.
在选择室外投影屏时，您应该按以下顺序回答三个问题：我的预算是多少我要多大我想要背面投影还是正面投影尽管在此之前我们还没有深入研究过，但是背投是您后院电影之夜工具包中非常方便的工具。
Traditionally, you project the image from the back of the audience onto the screen (just like in a regular movie theater). Movie theaters do it that way because it’s space efficient. The audience sits in the throw distance so no space is wasted behind the screen accommodating the long throw of a large projector. In your backyard, however, it’s often very handy to do a rear projection because no children or guests will get in the way of the light and you can hide the projector, cords, and even speakers all behind the screen out of the way and out of sight.
传统上，您将图像从观众的后方投射到屏幕上(就像在常规电影院中一样)。 电影院之所以这样做，是因为它节省了空间。 观众坐在投掷距离内，因此屏幕后面不会浪费任何空间，以适应大型投影机的长投掷。 但是，在您的后院，进行背投通常非常方便，因为没有孩子或客人会挡住光线，并且您可以将投影仪，电源线甚至扬声器全部隐藏在屏幕后面视线。
With all that in mind, let’s take a look at some common screen solutions.
考虑到所有这些，让我们看一些常见的屏幕解决方案。
床单和遮光布 (Bed Sheets & Blackout Cloth)
On the very cheapest side of things, you can get by with a bed sheet. Truly, you can! Iron a bed sheet to get it as wrinkle free as possible, and then secure the sheet in such a fashion that the sheet is kept fairly immobile and under a slight bit of tension. To do so you can do a few different things. Over the years (and before we invested in a real projection screen) we used white sheets without a problem and would secure them either by tying the corners to twine and stretching the fabric pretty tight between supports (like between the wall of the garage and a big tree in the yard) or–and this was a preferred method–we’d clip the top of the sheet to something sturdy like the garage gutters or a swing set and then clip the bottom of the sheet to a broom handle to provide weight and tension. It might not look super professional, but when the lights are out, nobody cares.
在最便宜的方面，您可以带床单。 确实可以！ 熨烫床单以使其尽可能没有皱纹，然后以这样的方式固定床单，使床单保持相当的固定性并承受一点张力。 为此，您可以做一些不同的事情。 多年来(在我们投资购买真正的投影屏之前)，我们使用白色板材没有问题，并且可以通过绑紧角落进行缠绕并在支撑物之间牢固拉紧织物(例如在车库的墙壁和地板之间)来固定它们。院子里的一棵大树)或-这是一种首选方法-我们将床单的顶部剪到坚固的东西上，例如车库排水沟或Swing，然后将床单的底部剪到扫帚手柄上以提供重量和紧张。 它看起来可能不是超级专业，但是当灯光熄灭时，没有人在乎。
If you want to keep things cheap but not splurge too much, we highly recommend going to your local fabric store and getting some blackout cloth. It’s a cotton/vinyl blend that is intended to be stitched to the back of curtains to, as the name implies, black out a room. The cloth itself, however, is a nice uniform white color and very sturdy. Two yards worth of blackout cloth is cheap and makes a great projector screen. In fact, when we built a home theater in our basement and didn’t want to splurge on a professional screen, we made a giant 200″ screen out of nothing but a pinewood frame with blackout cloth stretched over it. Five years later it still works great.
如果您想保持便宜，但又不想花太多钱，我们强烈建议您去当地的布料店买些遮光布。 它是一种棉/乙烯基混纺，旨在缝合到窗帘的背面，顾名思义，将房间涂成黑色。 布料本身是均匀的白色，非常结实。 两码的遮光布价格便宜，并且可以制作出不错的投影仪屏幕。 实际上，当我们在地下室建立家庭影院并且不想在专业银幕上挥霍时，我们只用一块松木框架加一块遮光布制作了一块200英寸的巨型银幕。 五年后，它仍然运行良好。
The big upside of using plain old thin white sheets is they are cheap and you can do front or rear projection. The downside is light cotton isn’t the best screen around. The upside of using blackout cloth is that it is remarkably well suited for projection, it’s relatively cheap, it’s very sturdy, and as long as you clip it to something sturdy it resists the wind very well. The downside is you can’t do rear projection.
使用普通的老式薄白纸的最大好处是价格便宜，您可以进行正投影或背投影。 不利的一面是，轻质棉并不是最好的屏幕。 使用遮光布的好处是，它非常适合投影，它相对便宜，非常坚固，而且只要将其夹在坚固的东西上，它就能很好地抵抗风。 缺点是您不能进行背投。
旧的室内投影幕 (Old Indoor Projection Screens)
While your HD projector might be brand new and definitely 21st century, analog projectors have been around forever and projection screen technology has changed very little. If you keep an eye on Craigslist, you can find old and new projector screens for dirt cheap. (As of this article there is a widescreen format roll-down projector screen on our local Craigslist for a mere $40!)
The tradeoff here is that often times the screens you find are 4:3 ratio instead of 16:9, and you’ll need to figure out some way to safely hang up the screen (or to weight down the stand if it came with one so it doesn’t blow over). The upside is you can find them super cheap and the screen is designed for projection and will have benefits like a semi-reflective coating to make the picture brighter. Rear projection roll-down screens are incredibly rare so if you go this route know that you’ll be doing front projection.
这里的权衡是，您通常会发现屏幕的比例是4：3而不是16：9，并且您需要找出一些方法来安全地挂起屏幕(或者在支架附带一个支架的情况下减轻其重量)因此不会爆炸)。 好处是您可以发现它们非常便宜，并且屏幕是专为投影而设计的，并且具有半反射涂层的优点，可以使图像更明亮。 背投下拉式屏幕极为罕见，因此，如果您走这条路线，将知道您将进行前投。
户外投影幕 (Outdoor Projection Screens)
Here’s where you’re getting into the making-an-investment territory. If you’re serious about throwing a top-notch outdoor movie night (and you plan on doing it with some frequency), it’s absolutely worth getting a nice outdoor movie screen.
这是您进入投资领域的地方。 如果您真的想举办一流的户外电影之夜(并且打算以一定的频率这样做)，那么绝对值得拥有一个不错的户外电影屏幕。
