Background
Crush the blacks — do not add fake black
The background should already be near-black from the dark room. In post, use Curves or Levels to bring the background to pure black (#000000). Do not use a vignette or gradient layer to fake black if the background went gray — it will look artificial. If it's too light, the answer is to shoot darker ambient next time.
Product Retouching
Clean the lid, protect the specular
Remove any dust or fingerprints on the lacquer lid with the Clone tool at 100% zoom. Protect the main specular highlight — cloning over it flattens the lid. The white CC logo ring should be bright white (#ffffff or close) but not blown. Use Dodge on the label text to improve legibility without touching the lid.
Color Grade
Neutral — don't add warmth or coolness
This setup is intentionally neutral — the cream of the container body is natural, the black is pure black. Don't add warmth (it makes cream look yellow) or coolness (it makes cream look clinical). Adjust white balance to exactly match the actual product color. A calibrated monitor is essential here.
Riser Surface
Smooth the gradient — remove imperfections
The curved riser may show scuffs, marks, or an uneven tonal gradient. Use the Healing brush at a large radius to smooth the gradient surface. The gradient from white to near-black should be perfectly smooth with no tonal steps or hotspots. Replace the riser between shoots to keep it pristine.
