Assignment
Declare your lighting signature by creating a simple SPHERE lit according to your approach — showing light direction, shadow quality, color temperature, and falloff. This is your lighting reference card, like a cinematographer's test shot.
Criteria: A sphere is visible. Lighting direction is clear and specific. Shadow quality (hard/soft) is identifiable. Color temperature is apparent. The lighting approach is unambiguous and could serve as a reference.
Intents
  • The primary light source will originate from the upper right at a 45-degree angle, casting a clear directional highlight and shadow on the sphere.
  • The shadow edge will be soft but well-defined, demonstrating a moderately diffused light source rather than a hard spotlight.
  • The color temperature of the light will be distinctly cool (bluish-white), while the ambient fill will be warm (subtle golden), creating a color temperature contrast.
  • There will be visible light falloff, with the sphere gradually transitioning from highlight to shadow, and the shadow on the ground fading gently at the edges.
  • The sphere’s form will be revealed by the lighting, with the far side receding into gentle darkness—no harsh outline—emphasizing form modeling and volume.
Scene Prompt
A single matte sphere sits centered on a neutral gray surface, against a mid-tone gray background. The primary light source is cool, bluish-white, shining from the upper right at a 45-degree angle, clearly defining the direction. The lit side of the sphere has a soft, diffused highlight, and the light transitions smoothly into shadow, with a visible gradient revealing the sphere’s curvature. The core shadow is soft-edged, the cast shadow is moderately diffused, and both show a gentle transition

Strengths
  • Lighting direction, shadow quality, and color temperature are all clearly communicated.
  • Excellent control of soft shadow edges and light falloff.
  • Color temperature contrast is subtle but distinct.
  • Form modeling is skillful, giving the sphere convincing volume.
Weaknesses
  • The only minor critique is that the warm fill could be made slightly more pronounced for maximum clarity, but it is present and effective.
Recommendation
Continue to refine subtle color temperature contrasts and experiment with even more nuanced falloff or edge control, but this work is more than ready for progression to more complex forms and scenes.
Reflection
[CRAFT] Attempt #1 (retry 1/3) on C1.4a. Score: 9.0/10. Intent-gap: 0%. Criterion met! Takeaway: Continue to refine subtle color temperature contrasts and experiment with even more nuanced falloff or edge control, but this work is more than ready for progression to more complex forms and scenes.
