In this tutorial we’ll talk about how SCRATCH reads out frame-based metadata from the most common RAW formats and forwards that metadata into OpenEXR renders for VFX.
From the OpenEXR site:
OpenEXR provides the specification and reference implementation of the EXR file format, the professional-grade image storage format of the motion picture industry. The purpose of format is to accurately and efficiently represent high-dynamic-range scene-linear image data and associated metadata, with strong support for multi-part, multi-channel use cases. The library is widely used in host application software where accuracy is critical, such as photorealistic rendering, texture access, image compositing, deep compositing, and DI.
OpenEXR a project of the Academy Software Foundation and is part of the VFX Reference Platform. OpenEXR was originally developed by Industrial Light & Magic (ILM) and first released in 2003. Weta Digital, Walt Disney Animation Studios, Sony Pictures Imageworks, Pixar Animation Studios, DreamWorks, and other studios, companies, and individuals have made significant contributions to the code base.
