Zenithal priming is a priming technique where you apply a dark base coat (typically black), then follow with a lighter primer (typically white or grey) sprayed only from directly above — the “zenith” — at a 45–90° angle to the model or surface. The result is dark recesses and undersides with lighter tones on top surfaces and raised areas, mimicking the way natural light falls.
Why it’s valuable:
- Creates an instant value map before you’ve applied any color — showing you where highlights and shadows should fall.
- When followed by transparent colors, the underlying light/dark values show through, automatically giving depth.
- Speeds up painting significantly for miniature artists and scale modelers.
Process:
- Prime with black or very dark grey from all directions.
- Load white or light grey.
- Airbrush from directly above (or 45° above) in thin, light coats.
- Don’t aim to cover everything — leave dark in the deepest recesses.
- Apply your transparent or semi-transparent color coats over this foundation.
