When taking photos with your iPhone, you may notice an option called "HDR." However, many users may not be clear on what HDR is exactly and how it affects the quality of their photos. In this article, we'll explain in detail what HDR is on the iPhone and how to use it correctly to capture better photos.
　　What is HDR?
　　HDR stands for High Dynamic Range. It's a photo processing technique aimed at presenting a wider range of brightness and richer details in photos. When you take an HDR photo, the camera captures multiple photos at different exposure levels and then combines them into one photo to preserve details with a broader range of brightness.
　　How Does HDR Work on iPhone?
　　On the iPhone, the HDR feature utilizes advanced image processing technology in the camera. When you enable the HDR feature and take a photo, the iPhone automatically captures three photos at different exposure levels: one normal exposure, one overexposed, and one underexposed. Then, the iPhone merges these three photos into one HDR photo to present a wider range of brightness and richer details.
　　What are the Advantages of HDR Photos?
　　There are many advantages to capturing photos using the HDR feature. Firstly, it helps you capture photos with a wider dynamic range and richer details, especially in complex lighting conditions such as backlighting or high-contrast scenes. Secondly, HDR photos often have better color and contrast, making the photos look more vibrant and realistic.
　　How to Use HDR on iPhone?
　　Using the HDR feature on the iPhone is straightforward. First, open the Camera app, then locate the "HDR" option at the top of the screen. It's usually located at the top of the camera interface or in the sidebar. Then, select "Auto" or "On" for the HDR feature, and the iPhone will automatically use HDR mode to capture photos in appropriate scenes.
　　When to Use HDR?
　　Although the HDR feature can help you capture better photos, it's not suitable for all situations. Generally, HDR works best when shooting scenes with backlighting, high contrast, or rich shadow details. Additionally, if you want photos with richer colors and contrast, you can also consider using the HDR feature.
　　How to View and Edit HDR Photos on iPhone?
　　Once you've captured HDR photos, you can easily view and edit them in the Photos app. Open the Photos app, then find the HDR photos you've taken. You can use the built-in editing tools to adjust the photos, such as cropping, rotating, adjusting brightness, and contrast.
　　HDR is a powerful photo processing technique that can help you capture better photos. On the iPhone, the simple and easy-to-use HDR feature allows you to effortlessly capture photos with a wider range of brightness and richer details. I hope I've helped you better understand the HDR feature on the iPhone and how to make the most of it when taking photos.

In Maya, lighting models is a common practice for rendering 3D models and virtual scenes. If you wish to negate the impact of lights on a specific model or completely remove lights to render a model or virtual scene without their influence, follow these steps:
<img src="https://img.relebook.com/news/edit/2023-12-8/54c9fa4f-7a11-4537-8a53-8363172bf7d6.png">
1. Open Relationship Editor:
&nbsp;&nbsp;&nbsp;Go to the "Window" menu and select "Relationship Editor."
2. Select Light-Centric View:
&nbsp;&nbsp;&nbsp;In the top-right corner of the Relationship Editor, find a button resembling a camera icon. Click this button to switch to "Light Centric View."
3. Unlink:
&nbsp;&nbsp;&nbsp;In the list of models on the right side, locate the model you want to exclude from the influence of lights. Click on the model name to select it, then click the adjacent minus sign (-) button to unlink the light from that model.
4. Preview and Render:
&nbsp;&nbsp;&nbsp;Use the real-time view or interactive rendering mode to confirm that lights no longer affect the selected model.
5. Remove Light from the Scene:
&nbsp;&nbsp;&nbsp;Using the Outliner or Hierarchy view, find the light object you want to delete. Select the light object and press the Delete key on your keyboard to remove it from the scene.
6. Delete Light from Material Editor:
&nbsp;&nbsp;&nbsp;If you added lights in the Material Editor (e.g., Hypershade), open the relevant Material Editor window, select the light node you want to delete, and click the "Delete" button in the top toolbar.
7. Clean Up Unused Resources:
&nbsp;&nbsp;&nbsp;To ensure all related resources are properly removed, you can execute the "Clean Up Unused" command. Go to the "Edit" menu, select "Clean Up," and then choose "Unused Nodes."
Before performing these actions, it's advisable to save your file and create a backup in case you need to revert to the original state or reconsider the removal of lights from the model.

How to Eliminate Lights from Models in Maya

Maya is a powerful tool in the realm of 3D animation and modeling, offering possibilities for both professional film production and personal artistic endeavors. Rendering lighting in a model or virtual scene is a crucial aspect that adds depth, texture, and overall enhancement to your work. Today, let's briefly explore how to render lighting in Maya.
<img src="https://img.relebook.com/news/edit/2023-12-8/6b71fa92-aafe-41f1-947a-0af862e74e3b.png">
Before rendering HDRI lighting in Maya, ensure you have set up your virtual scene. Open or create a new Maya scene and add at least one light source to your scene. You can choose from spotlights, area lights, or other types of light sources. Alternatively, you can add high-quality HDRI downloaded from reliable sources like Relebook based on your desired lighting effects. Next, ensure the position and angle of your light source illuminate the objects you want to highlight.
Once you've set up the virtual scene in Maya, enable shadows. Select your light source and, in the "Attribute Editor," locate the "Shadows" tab. Check "Enable Shadows." This step is crucial as lighting without shadows can appear unrealistic. Adjust lighting parameters to achieve the desired effect. This may involve tweaking the light source's color, intensity, attenuation, and more. When adjusting these parameters, use the real-time render preview feature for immediate feedback.
If needed, add some global illumination effects. Global illumination enhances realism by simulating indirect lighting as observed in the real world. In Maya, you can activate this feature by clicking on the "Global Illumination" tab within the "Render Settings" window.
Once you are satisfied with your lighting setup, you can proceed with the actual rendering. Click the "Render" button at the top of the "Render Settings" window, and Maya will start generating your image. This process may take some time depending on the complexity of your scene and rendering settings.
