  "title": "Enhance RAW image processing with Core Image",
  "description": "Harness the power of version 9 of the Core Image RAW processing APIs to dramatically improve image quality in your apps, with improved sharpness and more defined color, while using the Apple Neural Engine for optimal performance. Take advantage of the CIRAWFilter API to let your users edit RAW photos by changing exposure, noise reduction, sharpness, contrast and more. And explore new CIImageProcessor APIs that optimize performance by giving you precise control over tile sizing and buffer management.",
