Description
保持水平居中并45度视角的提示词：
-
the axis must be level,
-
left and right ends at the same height,
-
only the camera looks downward at 45°, not the product tilting itself.
Refine and enhance the uploaded wheel hub bearing image for luxury commercial advertising, producing a premium, high-end polished-industrial metal finsih product visual suitable for global automotive branding.
⚠️ The output must remain exactly the same product as the uploaded image — no redesign, no alteration of structure, no added or removed components.
Product Integrity & Accuracy (Critical)
Preserve 100% original geometry, proportions,bolts, dimensions, and mechanical accuracy.
Do not remove, smooth out, add, reduce, or alter any protrusions,bolts, recesses, grooves, flanges, steps, lips, cutouts, chamfers, or surface transitions.
All raised and recessed surface details must remain exactly as in the original image, including panel transitions and flange profiles.
No deformation, reshaping, stylization, or creative reinterpretation.
Material Accuracy (Strict Enforcement)
Top cap:
Made of black plastic, including the ABS sensor.
Must remain plastic only — do NOT convert to metal, chrome, or reflective material.
Maintain original texture, matte/plastic behavior, and color tone.
Main body & bearing assembly:
Precision-machined stainless steel.
Uniform, realistic metallic appearance with no mixed materials or artificial coatings.
Metal Finish (Luxury Industrial Grade)
Refined polished-industrial stainless steel finish.
Smooth, clean, premium surface — not mirror-like, not overly glossy.
Subtle, realistic reflections with controlled specular highlights.
No color tinting, no gradients, no brushed patterns unless originally present.
Consistent metal tone across all steel components.
Perspective & Alignment
Full perspective correction.
Perfect axial alignment and flattening.
The axis must be level,
left and right ends at the same height,
only the camera looks downward at 60°, not the product tilting itself.
Centered, balanced, and symmetrical presentation suitable for catalog and advertising use.
Lighting & Visual Clarity
High-end luxury studio lighting used in premium automotive advertising.
Brighter overall exposure with controlled highlights and soft shadow transitions.
Maintain realistic light flow across curves, chamfers, edges, recesses, and protrusions.
Accurate neutral white balance — no warm or cool color cast.
Background & Presentation
Pure white background (#FFFFFF).
Only a soft, natural contact shadow beneath the product.
No gradients, textures, reflections, or environmental elements.
Square format
Details & Branding Integrity
