景深

In its reflection over the reality, art comes as a mirror with a certain angle of reflection, and image and the depth of focus depending on the angle; the reflection is always accompanied with persistent blind spots which I would like to leave to my viewers.

艺术若反映现实，艺术便是一种镜效，它有呈现的角度，以及因角度而产生的观照和景深，它会有死角，有永远观照不到的空间，我把这个空间留给了观众。

This work deals with the depth information estimation of 3-D surface in a series of images from different shot angle.

解决从不同角度拍摄的一系列平面图像中解算图像中物体的景深问题，使用一个新颖的二阶先验模型来建模光滑3D物体的表面信息，此模型比传统的一阶模型有很大优势。

The apparent horizon is the factor that Yin Chaoyu emphasized a lot in many of his paintings, which has even turned certain "principal", but except emphasizing the depth of field like the past, this "principal" that makes people associate the classicality of external images has more structural meaning of pictures.

"地平线"，是尹朝宇在很多画中非常强调的部分，甚至成为了他创作中的某种"原则"，但是这一在表象上让人联想到古典的"地平线"，除了像过去那样以此来强调景深之外，更多的则是画面的结构性的意义。

Similarly, lens with high f-number have larger DOF than lens with low f-number.

景深是由几个因素影响，广角镜头通常比望远镜头有较大景深，高F值也有较大景深。

A large opening (small f-stop number) gives you a very shallow DOF, and a small opening (big f-stop number) gives you a much deeper DOF.

一个大洞的开启会带给你浅度景深，而一个小的开启则会给你一个深度景深。

The longitudinal conjugated property of ideal optical system ;2. Starting from the principle of photograph formation by an ideal optical system , this paper derives the formulas of field depth and hyperfocal distance.

本文从理想光具组成像原理出发推导出景深和超焦距的公式，物理思想明确，并结合公式绘出了景深与有关参量的直观图，摄影者容易理解和掌握。

Simply stated: A loupe with a longer working distance, will have a larger depth of field, and vice versa.

景深的大小直接和工作距离相联系，简单的说：手术放大镜的工作距离越长，景深就越大，反之亦然。

Simply stated: A loupe with a lower magnification factor, will have a larger depth of field, and vice versa.

景深的大小和放大倍率也有联系，简单的说：手术放大镜的放大倍率越小，景深就越大，反之亦然。

A scheme of microscope polarization interference imaging spectrometer based on a Savart polariscope and its basic principles are introduced,and the relative expression of depth of field of MPIIS is derived with the geometrical-optics method.

提出了一种基于萨伐尔偏光镜双折射晶体进行光谱分光的显微偏振干涉成像光谱仪的创新性原理和方案；从几何光学的角度推导了显微偏振干涉成像光谱仪景深的理论计算公式；给出了景深与光谱分辨力的变化关系，证明了景深的存在使系统光谱分辨力不再唯一确定，而是在一定范围内连续变化；通过计算机模拟分析了景深对系统分辨力的影响。

In "Chang'an Avenue", the original clear scene is smashed and changed into a flat wall which blocks our sight and interferes with our psychological needs of the depth of field when seeing photos. However, there is still a kind of flat visual form which makes the infinite depth transform into a limited flat. When facing the variegated image, we are made to find the reality so faraway and dim by the glint of the adjusted photo, the extremely clear marks and the deep hue which seems like the result of underexposure.

长安街》中，本来清晰可见的远景，在揉的过程中其客观存在被改变，演变成一堵平面的墙，封堵了人们的视线，打破了人们观看照片时对空间景深的心理需求，但又存在着一种平面的视觉形式，使无限的景深陡然变成了有限的平面，仿佛是曝光不足所导致的低沉色调与照片被处理后所带来的映衬着现实若隐若现的反光，以及清晰无二的皱痕，让人感觉在沧桑斑驳的平面前，现实是那么遥远与模糊。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
