Best viewed in Apple computers with an XDR display or computers with HDR display. If you don't see much difference when moving the slider, check the compatibility of your device.
Resulting images can be embedded in websites and they display in HDR, falling back to standard dynamic range in non-compatible devices.
Convert from Apple HEIC photos, Android UltraHDR JPGs, and industry standard EXR images for broad input compatibility.
Non-HDR images can also be provided and expanded to HDR, unlocking extended brightness and dynamic range for non-HDR sources.
