One of the most common problems photographers face is nailing focus. It’s always annoying when you think you’ve taken a good image on location and then go home to find your subject is slightly blurry. Here’s how to make sure your photos are always in focus.

摄影师面临的最常见问题之一是聚焦。 当您认为自己在位置上拍摄了不错的图像然后回家发现您的拍摄对象有点模糊时，总是很烦人。 这是确保照片始终清晰对焦的方法。

Focus is super important for photography. It’s a big part of taking sharp images and also a way to guide the viewer’s eyes. Humans are automatically drawn to the sharp areas of an image. If you miss focus, something will look subtly wrong, like in this shot of mine.

聚焦对于摄影来说非常重要。 这是拍摄清晰图像的重要部分，也是引导观众眼睛的一种方式。 人体会被自动吸引到图像的锐利区域。 如果您错过焦点，那么看起来有些微妙的错误，例如我的这张照片。

I messed up and focused on the guy’s hands. I love this shot otherwise but, sadly, since the focus is off, all I can do with it is use it as an example of my failings! Let’s make sure the same thing doesn’t happen to you.

我搞砸了，集中在那个家伙的手上。 否则我会喜欢这张照片，但可悲的是，由于焦点已关闭，因此我所能做的就是用它作为失败的例子！ 让我们确保您不会发生同一件事。

选择正确的光圈 (Select the Correct Aperture)

Focus and depth of field are related. The greater the depth of field, the more of your image will appear in focus. This means that aperture is a big part of focus—or really, a big part of how easy it is to focus.

焦点和景深有关。 景深越大，图像中出现的焦点越多。 这意味着光圈是对焦的重要部分，或者实际上是对焦容易程度的很大部分。

Photojournalists and street photographers have a maxim: “f/8 and be there.” In other words, at f/8 with a normal lens, as long as you don’t focus on the background or the extreme foreground, everything in your shot will be in focus.

摄影记者和街头摄影师的座右铭是：“ f / 8并在那里。” 换句话说，在使用普通镜头的 f / 8下，只要您不聚焦于背景或极端前景，拍摄中的所有内容都将清晰对焦。

Conversely, if you’re using a long lens and a wide aperture like f/1.8, the depth of field could be just a few centimeters. We looked at this in full in my article on how to focus with wide aperture lenses.

相反，如果您使用长镜头和f / 1.8之类的宽光圈，则景深可能只有几厘米。 我们在有关如何使用大光圈镜头进行对焦的文章中对此进行了全面研究。

If you want your image to be in focus, you need to select the correct right aperture for the job. Unless you need to use a wide aperture for creative or exposure reasons, you should pick something between f/8 and f/16. It makes things infinitely easier. If you need to use a wide aperture, go right ahead, just know that you’ll need to work that bit harder to keep your images sharp.

如果要使图像清晰，则需要为作业选择正确的右光圈 。 除非出于创意或曝光原因需要使用大光圈，否则应选择介于f / 8和f / 16之间的值。 它使事情变得无限轻松。 如果您需要使用较大的光圈，请继续前进，只是知道您需要付出更多努力才能保持图像清晰。

决定使用手动还是自动对焦 (Decide Whether To Use Manual Or Autofocus)

There are advantages to both manual and autofocus, especially when you take control of autofocus as we advocate here at How-To Geek. In general, you should default to autofocus unless:

手动对焦和自动对焦都具有优势，尤其是当您控制自动对焦时，正如我们在How-To Geek所倡导的那样。 通常，除非出现以下情况，否则应默认为自动对焦。

• You’re shooting using a tripod and want to focus at a specific distance rather than on a specific point.您正在使用三脚架拍摄，并且希望将焦点对准特定的距离而不是特定的点。

• You’re taking photos of the stars.

  您正在为星星拍照 。

• It’s too dark for your camera’s autofocus to reliably find focus.相机的自动对焦太暗，无法可靠地找到焦点。

• You’re shooting a set up action photo and want to pre-focus on the point where everything is going to happen.

  您正在拍摄一张准备好的动作照片，并希望将焦点预先对准一切将要发生的地方。

• You’re focussing through something like a field of grass, a tree, curtains, or anything else that will throw of autofocus.您正在聚焦于草地，树木，窗帘或其他任何会引起自动聚焦的事物。
• Autofocus has failed.自动对焦失败。

I love manual focus and use it a lot for landscapes, but it’s just too slow to use most of the time.

我喜欢手动对焦并将其用于风景，但大多数情况下使用它太慢了。

如果您手动对焦... (If You’re Focussing Manually…)

If you’ve decided to focus manually, we’ve got an article that walks you through the right way to do it. The main takeaway is to use your camera’s Live View screen and zoom in to 10x (or however far you can zoom in). This way, you’ll be able to make sure the smallest details are in sharp focus.

如果您决定手动进行对焦，我们将为您提供一篇指导您完成正确方法的文章。 主要的收获是使用相机的实时显示屏幕，并放大到10倍(或者您可以放大多远)。 这样，您将能够确保最小的细节成为焦点。

如果您正在使用自动对焦… (If You’re Using Autofocus…)

If you’re using autofocus, you have a few more decisions to make. You need to decide which autofocus point, or combination of autofocus points, and what autofocus mode to use.

如果您使用的是自动对焦，则还需要做出其他一些决定。 您需要确定要使用的自动对焦点或自动对焦点组合，以及要使用的自动对焦模式。

Your camera will give you the option to use a single autofocus point, a group of them, or the whole autofocus sensor to find focus. In general, a small group of autofocus points will give you the best balance as you can place it over your subject and let the camera do the rest, without fear of it finding focus on something random in the background.

您的相机将为您提供选择使用单个自动对焦点，一组自动对焦点还是使用整个自动对焦传感器来寻找焦点。 通常，一小撮自动对焦点会为您提供最佳的平衡，因为您可以将其放在对象上并让相机完成其余的工作，而不必担心它会发现背景中的随机物体。

You should use a single autofocus point if you’re shooting with a wide aperture lens and need a very specific thing to be in focus, such as your subject’s eye or a small bird in a tree.

如果使用大光圈镜头拍摄，并且需要非常具体的物体进行对焦，例如对象的眼睛或树上的小鸟，则应使用单个自动对焦点。

You should use the whole autofocus sensor when you need to be flexible, like when you’re doing street photography. If you’re not sure where your next subject is going to be, it’s okay to let the camera decide on a different focus point for every shot. This is especially effective when you’re using an aperture of f/8.

当您需要灵活操作时，例如在进行街拍时，应使用整个自动对焦传感器。 如果您不确定下一个对象将在哪里，可以让相机为每次拍摄决定一个不同的对焦点。 当您使用f / 8的光圈时，此功能特别有效。

You also have to decide what autofocus mode to use. The three options are:

您还必须决定要使用哪种自动对焦模式 。 这三个选项是：

• Single autofocus (One-shot AF or AF-S), which finds focus then stays locked.单次自动对焦(单次自动对焦或AF-S)，可找到对焦，然后保持锁定状态。
• Continuous autofocus (AI Servo or AF-C), which keeps trying to find focus.连续自动对焦(AI伺服或AF-C)，一直试图寻找焦点。
• Hybrid autofocus (AI Focus or AF-A), which acts like single autofocus until your subject moves and then acts like continuous autofocus.混合自动对焦(AI对焦或AF-A)，其作用类似于单次自动对焦，直到被摄对象移动，然后再进行连续自动对焦。

I recommend you use continuous mode and back button autofocus, but that’s an advanced trick. If you’re just starting, hybrid mode is the simplest and most flexible to use. If you know you’re shooting subjects that are always moving, switch to continuous. If you’re shooting landscapes or other subjects that aren’t going anywhere quickly, you can switch to single.

我建议您使用连续模式和后退按钮自动对焦 ，但这是一个高级技巧。 如果您只是开始，则混合模式是最简单，最灵活的使用方式。 如果您知道拍摄的对象一直在移动，请切换为连续拍摄。 如果您拍摄的风景或其他无法快速移动的物体，则可以切换到单张拍摄。

Sometimes when you’re using autofocus, your subject won’t fall exactly under the autofocus point or group you want to use. If this happens, use single focus mode, place the subject directly under the autofocus point you’re using, half-press the shutter button to focus on your subject, then keep the shutter button half-pressed to keep focus locked, recompose your image, and full press the shutter button to take the photo.

有时，当您使用自动对焦时，您的主题不会完全落在您要使用的自动对焦点或组之下。 如果发生这种情况，请使用单焦点模式，将被摄对象直接放在您使用的自动对焦点下，半按快门按钮以对被摄对象聚焦，然后半按快门按钮以保持聚焦锁定，重新构图，然后完全按下快门按钮拍照。

拍摄后检查 (Check After You Shoot)

Focus is one of the few things you really can’t fix at home. It doesn’t matter if you just missed focus by a few centimeters, you probably won’t be able to do much with a blurry image. This means you have to get the photo right on location.

专注是您真正无法在家中解决的少数事情之一。 如果您只错过了几厘米的焦点，那就没关系，您可能无法对模糊的图像做很多事情。 这意味着您必须正确放置照片 。

Every few minutes, take the time to go back over the photos you’ve shot using your camera’s screen. If there are any photos where you were using a wide aperture or might have missed focus for some other reason, zoom in to 10x and check; the screen is too small to know for sure without zooming in. If the photo’s not sharp, you can always take the photo again. If it is, then you know you’re safe.

每隔几分钟，请花时间返回使用相机屏幕拍摄的照片。 如果有任何照片使用大光圈或由于其他原因而错过了对焦，请放大10倍并检查； 屏幕太小，无法放大而无法确定。如果照片不清晰，可以随时重新拍摄照片。 如果是这样，那么您就知道自己很安全。

Being able to get focus reliably is an important skill for photographers to master. Even in tricky situations, you need to be able to come home with the photos you wanted to take.

能够可靠地对焦是摄影师掌握的一项重要技能。 即使在棘手的情况下，您也需要能够将想要拍摄的照片带回家。
