# Camera Capabilities Across Devices

## Overview
This sample shows how to apply the open camera capabilities of HarmonyOS across multiple devices, including Camera Kit for preview and photographing, photoAccessHelper for saving photos, and breakpoints for implementing different layouts and functionalities on multiple devices. By running this sample, you can implement features such as preview rotation, photo rotation, and camera switch on devices (smartphones, large-screen foldable phones, widescreen foldable phones, triple-screen foldable phones, and tablets) in either unfolded state or folded state.

## How to Implement

⦁	Use Camera Kit to preview and take photos.
⦁	Use photoAccessHelper to save photos.
⦁	Use breakpoints to implement different page layouts and functionalities on multiple devices.

## Required Permissions

⦁	Camera permission: ohos.permission.CAMERA, which is required for camera development.
⦁	Restricted permission - media library permission: ohos.permission.READ_IMAGEVIDEO, which is used to read files from Gallery. Applicable scenarios and functionalities: The application needs to clone, back up, or sync images or videos.
⦁	Restricted permission - media library permission: ohos.permission.WRITE_IMAGEVIDEO, which is used to save files to Gallery. Applicable scenarios and functionalities: The application needs to clone, back up, or sync images or videos.
