单反相机照片不见了
Smartphone cameras have come far,but they’re still no competition for a DSLR. The biggest problem isn’t actually the sensor, though—it’s the lens.
智能手机相机已经走得很远了，但它们仍然不是DSLR的竞争者。 最大的问题实际上不是传感器，而是镜头。
Most smartphones have something equivalent to a 35mm lens on a DSLR. If you take a photo in the same spot with a smartphone and a DSLR with a 35mm lens on, the pictures will look quite similar. The thing is that DSLRs can use dozens of different lenses.
大多数智能手机在DSLR上都具有相当于35mm镜头的功能。 如果您使用智能手机和装有35mm镜头的DSLR在同一地点拍摄照片，则照片看起来会非常相似。 问题是数码单反相机可以使用许多不同的镜头。
The look most people want to recreate with their smartphone is that of a lens with a wide aperture, like an 85mm f/1.8. The new iPhone 7 can do this in-camera with Portrait Mode, but for everyone else, we need to turn to Photoshop.
大多数人希望使用智能手机重现的外观是具有85mm f / 1.8的大光圈镜头。 新的iPhone 7可以在肖像模式下在相机内完成此操作，但是对于其他所有人，我们需要转向Photoshop。
现实生活中的影响 (The Effect in Real Life)
Before diving into Photoshop, let’s look at the effect we’re going to recreate in real life. Below is a photo I took of my brother Freddie with a 85mm f/1.8 on a Canon 5DIII.
在进入Photoshop之前，让我们看一下我们将在现实生活中重现的效果。 下面是我用85mm f / 1.8拍摄的我的兄弟房地美在佳能5DIII上拍摄的照片。
Freddie’s face and eyes are in focus, but the background is totally out of focus. Even his shoulders and the back of his hair is a little bit blurred. This is the kind of look we’re going for.
弗雷迪(Freddie)的脸和眼睛清晰可见，但背景完全不清晰。 甚至他的肩膀和头发的背面也有点模糊。 这就是我们想要的外观。
第一步：选择一张照片 (Step One: Select a Photo)
This effect works best with a well exposed headshot. Other subjects are much trickier to work with, and no amount of time in Photoshop can save a bad, overexposed image.
爆头曝光良好时，此效果最佳。 其他主题很难处理，在Photoshop中没有任何时间可以保存不好的，曝光过度的图像。
I’m using this simple selfie. It’s far from perfect, but it’s the kind of picture that this effect will work great on. The image of me is nice, but the background is just too busy.
我正在使用这个简单的自拍照 。 它远非完美，但是这种效果可以很好地发挥作用。 我的形象很好，但是背景太忙了。
Open the photo you want to use in Photoshop and let’s get started.
在Photoshop中打开要使用的照片，让我们开始吧。
第二步：应用效果 (Step Two: Apply the Effect)
Select the Background layer and go to Layer > Duplicate Layer, or pressControl+J on your keyboard (Command+J on a Mac).
选择背景图层，然后转到图层>复制图层，或在键盘上按Control + J(在Mac上为Command + J)。
Next, go to Filter > Blur Gallery > Iris Blur. This is the Photoshop filter that emulates the effects of a wide aperture lens.
接下来，转到“滤镜”>“模糊库”>“虹膜模糊”。 这是模仿宽光圈镜头效果的Photoshop滤镜。
There’s a lot going on here, so let’s break it down:
这里有很多事情，所以让我们分解一下：
Click and drag on the inner circle to move the centre point of the blur around.单击并拖动内圆，以移动模糊的中心点。 Click and drag on the outer ring to change the amount of blur that’s being applied.单击并拖动外圈以更改要应用的模糊量。 Click and drag on the large control handles to adjust the transition area of the blur.单击并拖动较大的控制手柄以调整模糊的过渡区域。 Click and drag on the small control handles on the solid ring to adjust the rotation and size of the un-blurred area.单击并拖动实心环上的小控制手柄，以调整未模糊区域的旋转和大小。 Click and drag anywhere else on the solid ring to adjust the size of the un-blurred area.单击并拖动实心环上的其他任何位置，以调整未模糊区域的大小。 Click and drag on the diamond on the solid ring to adjust how square or rounded the shape of the un-blurred area is.单击并拖动实心环上的菱形，以调整未模糊区域的形状的正方形或圆形。 Click anywhere outside the current area to add a new pin.单击当前区域之外的任何位置以添加新的图钉。
We want the effect to be centred on the subjects face, so start by moving the pin to roughly their nose.
我们希望效果以被摄对象的脸为中心，因此首先将图钉大致移动到他们的鼻子上。
Next, adjust the size of the un-blurred area so it covers just the subjects head. You’ll probably need to rotate it to get the best fit.
接下来，调整未模糊区域的大小，使其仅覆盖对象的头部。 您可能需要旋转它才能获得最佳配合。
This is starting to look okay.
这开始看起来还不错。
Now, we need to adjust the transition area so the falloff looks more natural. Move the large handles so they sit roughly on the subject’s chin, temples and hair. You’ll probably have to tweak some of the other variables, including the roundness, to get a good fit.
现在，我们需要调整过渡区域，以使衰减看起来更自然。 移动大手柄，使其大致坐在对象的下巴，太阳穴和头发上。 您可能需要调整其他一些变量，包括圆度，以达到理想的效果。
You can see my attempt below.
您可以在下面查看我的尝试。
To finish, adjust the blur until the effect looks good. I’ve gone with a value of 10px, but you should go with what works for your image.
要完成此操作，请调整模糊，直到效果良好为止。 我的值是10px，但是您应该选择适合您的图像的值。
And here’s my finished effect.
这是我完成的效果。
You can see how much more I stand out against the background with this before and after GIF. By keeping the effect subtle, it looks natural:
您可以看到在GIF前后，我在背景下脱颖而出还有多少。 通过保持效果微妙，它看起来很自然：
A smartphone will never compete with a DSLR, but with Photoshop, we can do a reasonable job of faking it. The edited version is a much stronger image than the original.
智能手机永远不会与DSLR竞争，但有了Photoshop，我们可以做得很合理。 编辑后的版本比原始版本具有更强的图像。
