电影合成老将乔纳森，麦克福尔提供本次研讨会上Nuke合成技术。这节课提出了无数的技术操作和2D元素整合成一个逼真的3D全景磨砂现场。乔纳森狂欢的快捷方式和专业的方式来实现影院级的效果。
Chapter Descriptions
Introduction
Film compositing veteran Jonathan McFall offers this workshop on Nuke compositing techniques. This lesson presents a myriad of techniques to manipulate and then integrate 2D elements into a photorealistic 3D panoramic matte scene. Jonathan revels the quick way AND the professional way to achieve cinematic results.

寻找和准备推出的元素
首先，我们准备从互联网上的照片通过快速键的磨砂喷漆共创美好阿尔法的照片。的某些部分需要一点滚塑创建垃圾遮罩。接下来，我们开始建设工厂随机图像的轮廓和明亮的场景，从随机的夜间照片。清理脚本，以使计算机运行速度略有提高，呈现出一个图像序列在Nuke的APLHA。
Finding And Prepping The Elements
First we prepare the photos from the internet for the matte painting by quickly keying the photos to create nice alphas. Some parts will require a bit of roto to create garbage mattes. Next, we start building the silhouette of a factory from random images and light the scene from random night-time photos. Clean up the script to make the computer run a little faster and render out an image sequence in Nuke with an aplha.

在3D环境中的2D
我们开始重新Nuke的3D环境，让你得到完全同出把投影卡的2D场景，但现在在3D环境中。只要将相机卡以扩展的照片，而不是使用2D变换节点。为了增加真实感和结婚的各种元素结合在一起，现在我们将做的云动画，使用Z模糊，使用焦平面设定，使用景深，最后从头开始创建一个自定义的背景虚化的旋绕的工具。
2D In A 3D Environment
We begin to recreate the 2D scene in Nuke's 3d environment by projecting each on to cards so that you get exactly the same out put, but now in the 3d environment. Simply move the cameras and cards to scale the photos, rather than using the 2d transform node. To add realism and marry the various elements together we will now: make the clouds animate, use the zblur, use the focal plane setup, use the depth of field and lastly create a custom bokeh from scratch with the convolve tool.

精致的细节
在本章中，我们潜下心来的调整，以达到现实主义的最细微的细节。蓝色和绿色的屏幕上提供的DE-泄漏表达的生产质量。 DE-噪音，然后RE粮食两种不同的方式：快速的方式，以专业的方式。按通道板，板的工作流程相匹配的粮食场景中的每个元素之间。我们总结了在这章的一个有趣的一点色差（色彩失真）用两种不同的方法。
The Fine Details
In this chapter we dive down to the adjust the finest details to achieve realism. A de-spill expression on blue and green screens offers production quality. DE-noise and then RE-grain in two different ways: the quick way and the professional way. Channel by channel, plate by plate this workflow matches the grain between each element in the scene.  We wrap up the chapter with a fun bit of chromatic aberration (chromatic distortion) with two different methods.

遇险的奇迹
第5章是重建的不完善，在现实生活中，一个摄像头创建。为了模拟现实是一个更好的和更逼真的磨砂喷漆。它不只是使一切看起来尽可能的干净，有时你必须使它看起来脏过。让我们添加一些火框架和重新定时的画面。将扩展项目设置的全景比率。包括随机播放/随机播放复制节点的详细说明。 Zdepth颜色分级采用非常微妙的另外的现实主义。接下来，我们使用了一个丰富多彩的背景虚化融合的前景，并模拟在相机镜头上的污渍和灰尘。进一步利用散焦和色差，创造一个真正的相机观看一个真正的景观的错觉。乔纳森提供了许多小的调整和变化，在这最后一章，企图实现“奇迹”发生时，写实。
Distress For A Miracle
All of chapter 5 is to recreate the imperfections that a camera creates in real life. To simulate reality is to make a better and more realistic matte painting. Its not just about making everything look as clean as possible, sometimes you have to make it look dirty too. Lets add some fire frames and retime the footage. Extend the project settings to a panoramic ratio. Included is a detailed explanation of the shuffle / shuffle copy nodes. Zdepth with color grading is employed for very subtle addition of realism. Next, we use a colourful bokeh to blend the foreground in and to simulate smudges and dust on the camera lens. Further use of defocus and chromatic aberration creates the illusion of a real camera viewing a real landscape. Jonathan offers many small adjustments and variations in this final chapter attempting to achieve the 'miracle' when photorealism occurs.

关于约翰·麦克福尔
乔纳森是一排字。他曾在拍摄的立体电影，电影转换成立体声，occula，准备作为一个艺术家和一个立体声转换艺术家。他开始了他的职业生涯作为Illustrator和Photoshop讲师。几年前，他发现了Nuke和现在他大呼过瘾。目前，他正在教在Nuke的晚上和一天的课程。乔纳森现在已经采取了他六年大学演讲经验和所学的知识，从工作15部电影，以建立一个培训为cmiVFX视频。他还喜欢在公园散步，和任何与外星人做。乔纳森最喜欢的地方是的吉格博物馆在瑞士。
About John McFall
Jonathan is a compositor. He has worked on films shot in stereo, films converted to stereo, in occula, as a prep artist and as a stereo conversion artist. He started off his career as an illustrator and photoshop lecturer. Then a few years ago he discovered Nuke and now he's hooked. He is currently teaching evening and day courses in Nuke. Jonathan has now taken his six years of university lecturing experience and the knowledge learnt from working on 15 films to create a training video for cmiVFX. He also likes walks in the park and anything to do with aliens. Jonathan's favorite place is the Giger museum in Switzerland.
