Chromium does not show its own color, but the entire environment of the studio.
The polished surface is understood only through reflections. An empty dark scene turns the product into a black spot, and a random room creates dirty ripples; shapes are built by controlled light stripes and coherent environment.
First, design what will be reflected.
For a glossy vial, it can be two large white cards on the sides, a dark central stripe and a warm accent at the back. Their reflections must continue along the surface without random breaks and explain each facet.
A long band of light works as a shape line.
On the convex body, the reflection bends smoothly, on a flat edge it remains almost straight, and on the sharp rib it changes direction. If the glare does not obey geometry, then the product appears crumpled or painted.
The camera can also appear in the reflection.
In a real shoot, it's hidden behind a black map or taken for an angle. In generation, check the central dark areas: the model sometimes finishes a vague silhouette of a person, a window or equipment that is not in the scene.
Describe light maps, not abstract "expensive shine"
Request.Take a studio photo of the chrome vial on the dark stone. Keep accurate geometry. Two large vertical light maps give continuous silver highlights to the sides, the center part remains dark, a warm narrow source reflects to your right, no random objects and no camera silhouette.
Track every major glare from start to finish
Check chromium on three scales.
In miniature. The silhouette should be read. On normal viewing. Large light and dark bands should explain the volume. Increase Look for torn glare, alien silhouettes, forked edges and mismatched reflections on the cover and body.
Compare it to the source, not the beauty of the frame, but the product invariants: height, width, radii, number of faces, position of dispenser and nature of coverage. If the geometry has changed, the new light no longer saves the card.
Beautiful glare should not hide the real material.
If the object is satin, matte or coated, mirror chromium will mislead the buyer. First fix the type of surface, then design reflections within its actual glossyness.
For the catalog, save a separate neutral master frame. Use the generated scene as an additional promo-visual, and not the only proof of the appearance of products.
For metal, the environment becomes part of a product.
When the reflections are designed, chromium looks material and premium. When they're random, even the exact geometry stops being readable.
