Compositing. Create an Atmospheric Snow Shot in Nuke and Maya. In this tutorial, we’ll be using Nuke's 3D System to take a still image and turn it into an atmospheric shot with camera moves and moving elements.

We’ll also be going over how to replicate some camera attributes such as grain as well. The technique shown has been used on a lot of feature films, and when done correctly, it can result in a good looking image in a short amount of time. Note: If you'd prefer to follow along using high resolution Images. You can download them below: High Resolution Tutorial Images 1. Step 1 Find an image, preferably square buildings and something that has depth, as well as finding something that is a high resolution. Open your image in Photoshop by going to File>Open.

Step 2 With your image in photoshop, we now need to go to Filter > Lens Correction. Step 3 With the Lens Correction screen up, click and hold the left mouse button and drag in and out of your image until your lines are as straight as you can get them. Step 4 Step 5 2. Step1 Create a camera in Maya. Step 2. Render passes, order + operation. "Passes," a.k.a. node-based rendering pipelines, are where the computers conspire to remind you that they really are digital computers, and that, to them, your "beautiful images" really are just enormous files of binary data.

Setting your sights firmly upon your "final output," which is (say...) "a great big matrix of (R,G,B) tuples," your objective is to systematically explore all of the possible ways that you can get there. Each of the various data sources that you are working with contain (when mapped into an X,Y,Z coordinate space...) probably many channels of information in addition to R, G, and B. But in any case, they can supply these channels of information, somehow, in terms of such a coordinate-space. Tutorial: Advanced VRay render elements compositing in After Effects.

Jun 22 '13 Author: Steven Olver Posted in: Blog Tutorial: Advanced VRay render elements compositing in After Effects Compositing VRay render passes is an important subject for the purposes of both quality and flexibility in our compositing workflow.

Being able to adjust colours, reflections and even individual lights in the scene long after the render is complete is not only exceptionally powerful, but also sometimes necessary for speedy turnaround on client changes. Linear Workflow The first step is to set up our linear workflow. Open up the Gamma and LUT settings from the Rendering menu in 3ds Max and check the following: “Enable Gamma/LUT Correction”, set the gamma to 2.2, check both “Materials and Colors” boxes, and set the bitmap input gamma to 2.2 and it’s output to 1.0. Next we need to make sure all our textures and images are set to the correct gamma. If in doubt, use 2.2. Lastly we need to use the VRay frame buffer instead of the Max frame buffer.
