ComfyUI Node: Advanced Camera Control Prompt Generator

Advanced Camera Control Prompt Generator:

The AdvancedCameraControlNode is a sophisticated tool designed to generate precise camera control prompts by interpreting camera information from Load 3D nodes. This node is particularly beneficial for AI artists who wish to create detailed and accurate camera setups in their projects. By leveraging predefined camera shots and angles, the node can automatically determine the most suitable camera configuration based on input parameters such as distance, focal length, and field of view. This functionality allows for a seamless integration of realistic camera perspectives into digital art, enhancing the overall visual storytelling. The node's primary goal is to simplify the process of camera setup by providing intuitive prompts that guide users in achieving the desired visual effects without requiring extensive technical knowledge.

Advanced Camera Control Prompt Generator Input Parameters:

camera_info

The camera_info parameter is a required input that accepts data from a LOAD3D_CAMERA source. It serves as the foundational information for the node to generate camera prompts, ensuring that the camera setup aligns with the 3D environment's specifications.

focal_length_mm

The focal_length_mm parameter is optional and allows you to specify the camera's focal length in millimeters. This parameter influences the camera's field of view and depth of field, affecting how subjects appear in the frame. The focal length can range from 1.0 to 1000.0 mm, with a default value of 50.0 mm, and can be adjusted in increments of 1.0 mm.

object_scale_meters

The object_scale_meters parameter is optional and defines the scale of objects in the scene in meters. This parameter helps in determining the appropriate camera shot type by considering the relative size of objects. It ranges from 0.01 to 100.0 meters, with a default value of 1.0 meter, and can be adjusted in increments of 0.01 meters.

custom_description

The custom_description parameter is an optional string input that allows you to provide a custom description for the camera setup. This can be useful for adding specific notes or instructions related to the camera configuration. The input can be multiline, offering flexibility in detailing the camera's purpose or unique characteristics.

Advanced Camera Control Prompt Generator Output Parameters:

prompt

The prompt output is a string that provides a detailed description of the camera setup based on the input parameters. This description includes the type of shot, camera distance, focal length, and field of view, offering a comprehensive overview of the camera's configuration.

camera_json

The camera_json output is a string that contains the camera configuration in JSON format. This structured data representation allows for easy integration with other systems or tools that require camera setup information, facilitating seamless workflow automation.

Advanced Camera Control Prompt Generator Usage Tips:

• To achieve the most accurate camera prompts, ensure that the camera_info input is correctly configured with data from a LOAD3D_CAMERA source.
• Experiment with different focal_length_mm and object_scale_meters values to see how they affect the camera's perspective and the resulting prompt. This can help you find the perfect setup for your specific artistic vision.

Advanced Camera Control Prompt Generator Common Errors and Solutions:

Invalid camera_info input

• Explanation: The camera_info parameter is not receiving valid data from a LOAD3D_CAMERA source.
• Solution: Ensure that the camera_info input is correctly connected to a LOAD3D_CAMERA node and that the data is properly formatted.

Focal length out of range

• Explanation: The focal_length_mm value is set outside the allowed range of 1.0 to 1000.0 mm.
• Solution: Adjust the focal_length_mm value to fall within the specified range, ensuring it is between 1.0 and 1000.0 mm.

Object scale out of range

• Explanation: The object_scale_meters value is set outside the allowed range of 0.01 to 100.0 meters.
• Solution: Adjust the object_scale_meters value to fall within the specified range, ensuring it is between 0.01 and 100.0 meters.
