We found that the best pictures have a very shallow depth of field, meaning that the subject is in crisp focus while the rest of the picture is blurry, like this

我们发现，最佳相片通常都是景深很浅的，也就是说相片的主体焦点很清晰，但背景却有点模糊的那种，比如下面这张

Portrait mode chooses a large aperture (a small 'f' number) which will make the depth of field (the amount of your shot in focus) smaller.

人像模式用一个大光圈(f值小)，而让景深(清晰对焦的那部分)变小。

The f-stop, otherwise known as the aperture, determines your depth of field (the area in focus) and how much light can pass through the lens to reach the sensor.

f制光圈(或称光圈)决定相机的景深(对焦区域)以及有多少光能通过镜头到达传感器。

You set the aperture, which dictates how much light comes into the camera-do you want a nice, shallow depth-of-the-field, or everything in focus?

你设置光圈(用于指定有多少光进入照相机镜头)——你想照一幅漂亮、浅景深或广角的照片吗？

FocusBlur: Makes an image out of focus with luminosity and depth.

FocusBlur：通过亮度和深度使图像失焦。

Some of the most interesting search engines we found are those that focus on a narrow niche and deliver in-depth targeted results on very narrow topics.

我们发现的搜索引擎中最有趣的是那些只专注于有限的领域并在那些又偏又冷的话题上提供深度搜索结果的搜索引擎。

The breadth of the change and its impact on the organization is considered above everything else, whereas the depth of the change is usually the focus in vertical top-down or bottom-up approaches.

更改的广度及其对组织的影响得到最优先的考虑，而更改的深度则通常集中于垂直的自顶向下或自底向上的方法。

Someday I would love to focus on climbing well in a comp, but at the moment, i am too intrigued with the depth of rock itself, i have so much more to learn, and so many more areas to explore!

或许有一天我会热衷于参加比赛争夺名次，但是此刻，我更对岩壁本身感兴趣，有那么多路线需要去体验，那么多神奇的领域亟待我去尝试！

The exam will focus in depth on three essential areas of math: Problem Solving and Data Analysis, the Heart of Algebra, and Passport to Advanced Math.

考试将深度聚焦在数学的三个关键领域：问题解决能力和数据分析，核心代数，以及向高等数学的过渡。

Part 2 will focus on process anatomy, taking a more in-depth look at Lombardi's development capabilities, and introduces the main BPM elements of the solution.

第2部分将侧重于流程剖析，深入探究Lombardi的开发功能，并介绍解决方案的主要BPM组成。

As such, I will focus the remainder of this article on learning about the role of the subject class in JAAS, with an in-depth discussion of subject-based access control.

因此，在本文的其余部分我将着重介绍JAAS中subject类的作用，并深入讨论基于subject的访问控制。

We teach them survey, focus groups, in-depth interviews, " says Hai Che, marketing professor at UC Berkeley's Haas School of Business. "That can be a high-quality but low-cost method."

我们教他们调研，目标机构，深度访问，”海切说，他是～～～的营销学教授，“这将是个低成本高质量的方法.”

This is because an image can have a varying Blur Width (depth of field) and the subject which is to be in focus is usually in the center.

这是因为图像可能有不同的模糊边缘宽度（景深）和在该中心通常有需要聚焦的被摄物体。

Telocentric lenses work with a wide depth of field. with a telocentric lens, you can image objects of different distances from the lens and the objects stay in focus.

具端著丝粒的镜头(注：我猜是类似于针孔镜头吧)具有宽阔之景深，以具端著丝粒的镜头，你能够将由镜头不同距离之目标物成像和保持目标物在焦。

Focus: plane of focus; focal length; and depth of field.

焦距：焦点平面，焦距和景深。

Based on the diffraction optics, this paper analysis the effect of aperture matching on EMR, size of focus point and focus depth of the object in detail.
