Feature Introduction
HDR (High Dynamic Range Imaging) is an imaging technique that captures and displays a greater dynamic range of exposure. It preserves more details and color information in images, making the contrast between light and dark areas more distinct and the colors more vibrant, thereby providing a more realistic and rich visual experience.
Cloud Infinite supports retaining the original HDR information during HDR image processing, enabling the processed images to still display the HDR effect.
Use Limits
Currently only supports some HDR types and image formats; see the table below:
|
JPG/JPEG: Ultra HDR (ISO standard GainMap HDR) | Processing upon download |
HEIF/HEIC: 10-bit native HDR, Apple standard GainMap HDR | Processing upon download |
AVIF: 10-bit native HDR | Processing upon download |
Note:
HDR images are a paid service. When used in combination with basic Image Processing, HDR image processing fees will be charged. If the processed image is in HEIF/HEIC or AVIF format, fees will be charged for both advanced image compression and HDR image processing. For detailed billing information, see Image Processing fees. Use Cases
Professional Photography Field
Preserve HDR information in professional photography images without worrying about image distortion.
Social, E-Commerce, Etc.
Major smartphone manufacturers have gradually supported capturing HDR images. Image processing that preserves HDR information can significantly enhance users' image viewing experience for services.
Prerequisites
You have enabled the COS service, created a Bucket, and uploaded images to the Bucket. For specific operations, see Bucket files. Enable the Cloud Infinite service and bind the Bucket. For specific operations, see Bucket Binding. Usage
Cloud Infinite provides the following methods for HDR image processing:
API: The HDR image processing method is fully compatible with Cloud Infinite's existing Image Processing features. You can preserve HDR information during image processing by appending hdr/1 to the basic image processing parameters. For operations related to image processing, see HDR Image Processing API.
