    This video demonstrates creating High Dynamic Range Images and using them as lights in Maya. This is the 'budget' HDRI, when you don't have a 5D Mark II and a fisheye lens. This video shows techniques that you can use with a entry level Canon DSLR with a tripod and a chrome sphere. Once the bracketed exposures are taken, we merge them together in Photohop, then take them into Nuke to unwrap them and remove unwanted artifacts. Then we bring it into Maya and set up our renders.

    Special care is taken so that we have two different HDRIs, one that is blurred (convolved) for smoother Final Gathering, and a high resolution HDRI for sharp reflections.

    We spend a lot of time and effort trying to make our perfect CG renders look a little less perfect. Chromatic aberration is one of those tricks that every compositor has to pull out at some point, and it is also the perfect effect to use as a demonstration of the differences between the way After Effects and Nuke work.

    In this tutorial, I will show you how to achieve this effect in both After Effects and Nuke, and I will attempt to make a very strong case as to why Nuke is a better program for doing look-development and compositing. As I mention in the video, you can download a 15-day free trial of Nuke here:

    I also mention the e-book I am currently working on. The e-book will be a very in-depth step-by-step guide to building your own Motion Graphics Freelance career. My goal is to explain precisely how to get clients, make them happy, build a brand, and make six-figures. I will be giving away free business tips and other goodies to members of the School of Motion mailing list, so make sure you sign up!

  3. A simple tutorial in Nuke on how to clone from one area of a moving image to another, using 2D tracking and stabilization, and basic compositing. Uses a shot from The Hotdog Cycle, produced by The Last Quest in Seattle.

    This video is also on my website in a post about cleanup work in visual effects.

    Update: 2011-05-23
    I have learned a lot since I made this tutorial, and wanted to point out something. The method I am using to stabilize the plate and then invert the stabilization will result in a loss of quality.

    Stabilizing results in a "filter hit" for the entire image, and then inverting the stabilization creates another filter hit. A filter hit is when a 2D transformation is applied to the image. In Nuke you have the choice between many different filtering methods, such as Cubic, Riffman, Parzen, etcetera. They vary in sharpening, but all will degrade your image.

    A better approach would be to create a tracker, or bring in a cornerpin track from Mocha, but matchmove only the part of the image you are altering on top of the original plate. This will result in the least image degradation.

    There are a lot of other things about this little tutorial I would do differently now also. The new "clone from source" feature of roto nodes in Nuke 6 would make doing this technique possible in a lot fewer nodes than I am using.

    Perhaps I will make some better tutorials when I have time soon!

  4. A demonstration of a method of cleanup using clone-painting from adjacent frames on a stabilized plate, in NukeX 6.0. Also demonstrated is plate stabilization, "patching" areas of the frame with a still image, and degraining and grain-matching using the Furnace grain tools, in order to preserve the grain structure of the shot.

    The shot used is from the animation "High Strung", produced by Tommy Thompson at The Evergreen State College.

  5. Relight a color pass in nuke by using a normals pass and point position pass generated from any 3D package.

    I'm using EXR images to encode both positive and negative values for normals and point positions, so make sure when you render from any 3D package to use 32 bit or floating point data.

    The color pass is simply a constant shader with a texture map applied.

    Nuke 6.2 should come standard with relight as a plugin.

    If you don't have the relight plugin for nuke download it from here:
