🐳HDR:
The HDREffectNode is designed to enhance the dynamic range of images, allowing for a more vivid and detailed visual representation. This node is particularly beneficial for AI artists looking to improve the quality of their images by adjusting the contrast between the darkest and lightest parts. By applying HDR (High Dynamic Range) techniques, the node can bring out details in shadows and highlights that might otherwise be lost, resulting in a more balanced and visually appealing image. The node offers various tone mapping options and allows for fine-tuning of details, local contrast, and shadow enhancements, making it a versatile tool for achieving professional-grade image enhancements.
🐳HDR Input Parameters:
image
This parameter represents the input image that you want to enhance using HDR techniques. It is the primary data that the node processes to produce an output with improved dynamic range.
HDR强度
This parameter controls the intensity of the HDR effect applied to the image. It ranges from 0.0 to 1.0, with a default value of 0.5. A higher value increases the HDR effect, enhancing the contrast and details in the image.
色调映射
This parameter allows you to select the tone mapping algorithm used in the HDR process. Options include "Reinhard," "Drago," "Mantiuk," and "线性." Each option provides a different approach to tone mapping, affecting the final appearance of the image.
细节增强
This parameter adjusts the level of detail enhancement applied to the image. It ranges from 0.0 to 1.0, with a default value of 0.5. Increasing this value enhances the fine details in the image, making textures and edges more pronounced.
局部对比度
This parameter controls the local contrast enhancement, ranging from 0.0 to 1.0 with a default of 0.5. It affects the contrast within smaller regions of the image, helping to bring out details in areas that might otherwise appear flat.
高光压缩
This parameter manages the compression of highlights in the image, helping to prevent overexposure in bright areas. It ranges from 0.0 to 1.0, allowing you to fine-tune the balance between preserving highlight details and maintaining overall brightness.
阴影提升
This parameter enhances the visibility of shadow areas in the image, ranging from 0.0 to 1.0 with a default of 0.0. It helps to reveal details in darker regions without affecting the overall contrast too much.
🐳HDR Output Parameters:
IMAGE
The output is an enhanced image with improved dynamic range and detail. This image reflects the adjustments made based on the input parameters, showcasing enhanced contrast, detail, and color balance, resulting in a more visually appealing and professional-looking image.
🐳HDR Usage Tips:
- Experiment with different tone mapping options to see which best suits your image's style and lighting conditions.
- Use the HDR强度 parameter to find a balance between enhancing details and maintaining a natural look.
- Adjust the 细节增强 and 局部对比度 parameters to bring out textures and depth in your image, especially in areas with complex patterns or subtle variations.
🐳HDR Common Errors and Solutions:
"Invalid image format"
- Explanation: The input image is not in a supported format.
- Solution: Ensure that the image is in a compatible format such as JPEG or PNG before processing.
"Parameter out of range"
- Explanation: One or more input parameters are set outside their allowed range.
- Solution: Check the parameter values and ensure they are within the specified minimum and maximum limits.
"Tone mapping option not recognized"
- Explanation: An invalid tone mapping option was selected.
- Solution: Choose a valid tone mapping option from the provided list: "Reinhard," "Drago," "Mantiuk," or "线性."
