Apple ProRes Log technical information or white paper?
Apple announced ProRes with Log encoding on the iPhone 15 Pro's but there isn't much technical information available. Most Log profiles have documentation how they are supposed to be exposed and other information, for example Sony S-Log: https://pro.sony/s3/cms-static-content/uploadfile/06/1237494271406.pdf
All I can find for Apple Log is a one-line reference to the mode on the developer docs: AVCaptureColorSpace.appleLog | Apple Developer Documentation
Apple Log looks promising but we're going to need more information on it.
