ComfyUI Node: Save Image (HDR)

Save Image (HDR):

The SaveImageHDR node is designed to save High Dynamic Range (HDR) images, which are known for their ability to represent a wider range of luminance levels compared to standard digital imaging techniques. This node is particularly useful for AI artists who work with HDR content and need to preserve the high-quality details and dynamic range of their images. By using this node, you can efficiently save your HDR images with a specified filename prefix, ensuring that your work is organized and easily accessible. The node leverages advanced image processing libraries to handle the HDR format, making it a reliable tool for maintaining the integrity and quality of your images.

Save Image (HDR) Input Parameters:

images

This parameter expects a list of images in the HDR format that you want to save. The images should be in the form of tensors, which are typically used in deep learning frameworks. Each image in the list will be processed and saved individually. The quality and details of the HDR images are preserved during the saving process.

filename_prefix

This parameter allows you to specify a prefix for the filenames of the saved images. The default value is "HDR/ComfyUI". This prefix helps in organizing and categorizing your saved images, making it easier to locate them later. The node will automatically append a counter and the ".hdr" extension to each filename to ensure uniqueness.

Save Image (HDR) Output Parameters:

This node does not produce any direct output parameters. Its primary function is to save the provided HDR images to the specified directory with the given filename prefix.

Save Image (HDR) Usage Tips:

• Ensure that the images you provide are in the correct HDR format to avoid any issues during the saving process.
• Use a meaningful filename prefix to help organize your saved images, especially if you are working on multiple projects or versions.
• Verify the output directory to ensure that you have write permissions and sufficient storage space for saving the HDR images.

Save Image (HDR) Common Errors and Solutions:

Failed to save image!

• Explanation: This error occurs when the node is unable to save the HDR image to the specified directory.
• Solution: Check if the output directory exists and that you have the necessary write permissions. Ensure that there is enough storage space available.

Invalid image format!

• Explanation: This error occurs when the provided images are not in the expected HDR format.
• Solution: Verify that the images you are providing are in the correct HDR format. You may need to convert or preprocess your images before using this node.

Filename prefix conflict!

• Explanation: This error occurs when there is a conflict with the specified filename prefix, leading to potential overwriting of existing files.
• Solution: Use a unique filename prefix to avoid conflicts. The node automatically appends a counter to each filename, but ensuring a unique prefix can help prevent any issues.
