Non-metallic metal (NMM) is the technique of painting metallic surfaces without using metallic paints. It's challenging but creates stunning, photographic results.
Understanding Light Placement
NMM is all about mimicking how light reflects off metal. Establish a consistent light source and stick to it. Sky-earth reflection is the most common approach.
- Define your light source first
- Highest points get brightest highlights
- Sharp transitions sell the effect
- Dark lines separate metal plates
Color Recipes
Different metals use different color progressions. Steel uses black to white through blue-greys. Gold runs from dark brown through yellows to near-white. Practice these transitions.
- Steel: Black > Dark Blue-Grey > Light Grey > White
- Gold: Dark Brown > Burnt Orange > Yellow > Pale Yellow > White
- Copper: Dark Brown > Red-Brown > Orange > Pale Orange
- Build transitions with many thin layers
Common Mistakes
Avoid muddy transitions - NMM needs sharp contrast. Don't make everything shiny - vary your surfaces. Remember that curved surfaces reflect differently than flat ones.
