👤 Person Perspective Control Input Parameters:

preset

The preset parameter allows you to select from six predefined perspective presets, each designed to evoke specific psychological effects. These presets include high, low, side, eye-level, three-quarter, and dutch angles. Choosing a preset will automatically adjust the camera perspective to achieve the desired effect. If you prefer a custom angle, you can select the "custom" option and specify your own angle description. This parameter is essential for setting the overall mood and impact of the photograph.

custom_angle

The custom_angle parameter is used when the "custom" option is selected for the preset parameter. It allows you to define a specific angle description that is not covered by the predefined presets. This parameter gives you the flexibility to experiment with unique perspectives and tailor the composition to your creative vision. It is particularly useful for advanced users who want to explore unconventional angles.

identity_level

The identity_level parameter controls the degree of identity preservation in the photograph. It offers three options: strict, moderate, and loose. A strict setting ensures that the subject's face, clothes, and pose remain identical, while a loose setting allows for more variation. This parameter is crucial for maintaining the subject's identity, especially in portrait and character photography, where consistency is important.

scene_context

The scene_context parameter provides additional context for the scene being photographed. It helps in building a more accurate and relevant perspective prompt by considering the environment and background elements. This parameter enhances the overall composition by ensuring that the perspective changes are coherent with the scene's context.

👤 Person Perspective Control Output Parameters:

prompt

The prompt output parameter is a text description that encapsulates the chosen perspective, identity level, and scene context. It serves as a guide for photographers and artists to achieve the desired composition and psychological effect. The prompt is a crucial output as it provides clear instructions on how to set up the shot to meet the creative objectives.

system_prompt

The system_prompt output parameter is a research-validated prompt that incorporates the latest findings and community-tested techniques. It provides a comprehensive guide for achieving the desired perspective and psychological effects. This output is essential for ensuring that the perspective changes are based on proven methods and best practices.

👤 Person Perspective Control Usage Tips:

• Experiment with different perspective presets to find the one that best suits the mood and message you want to convey in your photograph.
