ComfyUI Node: ⚡| Photo-Style Prompt Encoder

⚡| Photo-Style Prompt Encoder:

The PhotoStylePromptEncoder node is designed to transform a text prompt into an embedding that is specifically adapted to a selected photographic style. This node is particularly useful for AI artists who wish to generate images with a specific visual aesthetic. By taking a text prompt, the node adjusts its visual style according to the chosen photographic style option and encodes it using a provided text encoder. This process results in an embedding that guides the image generation process, ensuring that the final output aligns with the desired photographic style. The node is part of the ComfyUI-ZImagePowerNodes suite, which is tailored for the "Z-Image" model, offering a seamless integration for artists looking to enhance their creative workflows with style-specific image generation.

⚡| Photo-Style Prompt Encoder Input Parameters:

clip

The clip parameter is the CLIP model used for encoding the text. It is essential for the node's operation as it tokenizes and encodes the text prompt into an embedding. The CLIP model must be valid and properly loaded; otherwise, the node will not function correctly. There are no specific minimum or maximum values for this parameter, but it must be a valid CLIP model instance.

customization

The customization parameter is an optional multi-line string that allows you to customize existing styles. Each style definition should start with ">>>" followed by the style name, and then include its description on the subsequent lines. The description should incorporate "{$@}" where the main text prompt will be inserted. This parameter provides flexibility in defining unique styles that can be applied to the text prompt. There are no specific minimum or maximum values, but the format must be followed for the customization to be recognized.

style_to_apply

The style_to_apply parameter is a combo box input that allows you to select the style you want for your image. It includes options from predefined photographic styles and any custom styles you have defined. The available options are dynamically generated based on the styles available in the system. The default option is "none," which means no style will be applied.

text

The text parameter is the main text prompt to encode. It supports multiline input and dynamic prompts, allowing for complex and detailed descriptions. This parameter is crucial as it forms the basis of the embedding that will guide the image generation. There are no specific minimum or maximum values, but the text should be meaningful and relevant to the desired image output.

⚡| Photo-Style Prompt Encoder Output Parameters:

Conditioning

The Conditioning output is the encoded text used to guide the image generation. This output is a result of the text prompt being tokenized and encoded by the CLIP model, with the selected photographic style applied. It serves as the primary input for subsequent nodes in the image generation pipeline, ensuring that the generated image aligns with the desired style and content.

String

The String output is the prompt after applying the selected photographic style. This output provides a textual representation of the prompt with the style adjustments, allowing you to verify how the style has been applied to the original text. It is useful for understanding the modifications made to the prompt and ensuring that the style application aligns with your creative vision.

⚡| Photo-Style Prompt Encoder Usage Tips:

• To achieve the best results, ensure that the clip model is correctly loaded and compatible with the node. This will prevent errors and ensure accurate encoding of the text prompt.
• Experiment with different style_to_apply options to see how various photographic styles affect the final image. This can help you discover new creative possibilities and refine your artistic vision.
• Use the customization parameter to define unique styles that are not available in the predefined options. This allows for greater creative flexibility and personalization of the image generation process.

⚡| Photo-Style Prompt Encoder Common Errors and Solutions:

ERROR: clip input is invalid: None

• Explanation: This error occurs when the clip input is not provided or is invalid. It indicates that the CLIP model required for encoding the text is missing or improperly loaded.
• Solution: Ensure that a valid CLIP model is loaded and connected to the node. If the CLIP model is from a checkpoint loader node, verify that the checkpoint contains a valid CLIP or text encoder model.
