For those more comfortable with a more traditional compositing package I wanted to share in this addendum post how to perform the same conversion using the OCIO implementation in the open source compositor Natron.
In this post we’ll wrap up the completion of our custom Color Transform. A LUT that’s unique to our camera characteristics that can be used with Blender’s implementation of OCIO to convert 8-bit camera footage into Scene Referred Space values perfect for more convincing compositing.
Working in Scene Referred Space will help you create more convincing, more accurate CG integration with background plates and remove much of the compositing guesswork of a Display Referred Space workflow. In this post we’ll take the data we captured from our camera and use some math to build a nice smooth response curve to generate a 1D LUT (Look Up Table) that will be used as a color transform in our favorite 3D package or compositor.
The continuing adventures of a Scene Referred VFX workflow on a budget. It starts with capturing our camera package’s dynamic range.
Champagne logarithmic camera output dreams on a beer budget? In this post I introduce a methodology for getting a scene referred video suitable for VFX out of a budget DSLR.
