The following are the system requirements for the correct display of tones for HDR photos recorded in HLG (HLG photos) on Nikon digital cameras that support tone-mode selection.
|GPU||HDR10 compatible with support for PlayReady digital rights management (DRM)|

|Software||NX Studio (be sure to install the latest version)|
Monitors That Do Not Satisfy the DisplayHDR 1000 Standard
Highlights in HLG photos may seem “washed out” when viewed on DisplayHDR/True Black 400, 500, or 600 monitors.
“HDR” and “HLG”
- High dynamic range (HDR) is an imaging technology that supports a range of tones (dynamic range) wider than is offered by existing techniques. It expands the potential for visual expression by increasing the range of luminosities captured in mid-tones and highlights. It is distinct from multi-exposure HDR capture, a high-dynamic-range imaging (HDRI) technique that blends multiple still photographs shot at different exposures.
- Hybrid log-gamma (HLG) is an HDR display standard. You can take HLG photos by selecting the [HLG] tone mode on Nikon digital cameras.
To display HLG photos, you will need to install Nikon’s NX Studio software. Doing so allows you to view and edit photos and videos shot with Nikon digital cameras. Download the latest version of the NX Studio installer from the website below and follow the on-screen instructions to complete installation.
Installing the Codec
Viewing HLG photos in NX Studio requires the corresponding “Imaging Codec 01” codec. The codec can be installed by following the instructions displayed the first time an HEIF-format (extension “.hif”) HLG photo is opened, selected, or saved in another format in NX Studio.
- You must provide the camera serial number before downloading Imaging Codec 01.
Configuring Your Computer
The computer must be configured as described below. More information on the settings below is available from the Microsoft website.
- Enable HDR in Windows display settings.
- Enable HDR video streaming.
Displaying HLG Photos in Single-Frame View
Selecting high values for HDR/SDR brightness balance will brighten the entire display, making the difference between HLG and non-HLG (SDR) photo displays difficult to discern. We recommend selecting the lowest setting for HDR/SDR brightness balance when viewing HLG photos.
Depending on the model, you may need to adjust settings on your monitor. See the monitor documentation for more information.
