1·This is the application of depth of focus.

在摄影中总是不能娴熟地加以运用。

2·Exposure energy, improvement of resolution and depth of focus are compared with that of conventional condition.

主要就曝光能量，分辨力改善情况，焦深变化等与传统情况作了比较。

3·Placing a diffractive optical element(DOE) on the incident laser beam to improve the depth of focus, the DOE'S aperture is variable.

在入射光束的孔径受限制的情况下，利用衍射光学元件来增加激光束的焦深。

4·It makes the central maximum in the Airy pattern narrower and increases the depth of focus. Calculation results have shown that this kind of apodizer is superior to the phase-shifting apodizer.

模拟计算结果表明，在中心峰值强度相等的条件下，用该器件所获得的超分辨效果比目前最好的纯相位型超分辨光阑要好。

5·Focus isn't just about what to focus on, it's also about how much depth of field to show in the portrait.

对焦不仅仅是考虑对在那里，还要考虑这幅人像要用多大的景深来表现。

6·Essentially, startups focus on breadth of knowledge, while enterprise focuses on depth of knowledge.

基本上创业公司专注于技术的广度，而大企业专注于技术的深度。

7·To borrow a term from the visual arts, Franzen's writing has an enviable depth of field: it keeps a great deal in focus simultaneously.

借用视觉艺术中的一个术语，弗兰岑的小说有一种令人艳羡的视角深度：它同时关注许多方面。

8·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

9·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。

10·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。
