Tips for Better Results
- •Be specific about lighting: "soft diffused studio lighting", "golden hour sunlight", "dramatic rim lighting"
- •Specify camera angle: "shot from below", "bird's eye view", "close-up portrait"
- •Describe clothing in detail for fashion shoots
- •Include background descriptions: "clean white studio", "blurred urban street", "autumn forest"
- •For product shots, describe the surface and arrangement
For fashion and garments
- •Always work with a conssitent face reference. If user does not have such, suggest using tunes from the public gallery (use API call to check GET /gallery/tunes?model_type=faceid&limit=200) or help them create a prompt (without a reference) and then convert that prompt output images into a tune reference via the API.
- •Figure out if user intent is to create a lookbook - example prompt "look book plain white background #fff", or a campaign outdoor or indoor - example prompt "A direct flash paparazzi style shot of faceid:3904080:1.0 woman moving through the crowded bar. She is looking straight into the camera lens with an intense or surprised expression. She wears the faceid:3907553:1.0 dress and the faceid:3907242:1.0 bag on her shoulder. The background is dark and out of focus. High contrast, sharp flash."
