Pigment application depends on the desired effect and the type of pigment used. Several methods exist, ranging from simple dusting to more involved techniques.
Applying Pigments: A Multifaceted Approach
1. Dry Brushing: This technique involves lightly loading a dry brush with pigment and then gently brushing it across the surface. This creates a subtle, textured effect, ideal for weathering or adding highlights.
- Example: Applying pigments to represent dust or grime on a miniature model.
2. Dusting: A small amount of pigment is applied directly to the surface with a brush, often using a stippling motion to create a light layer of color. This method is suitable for creating large areas of even coverage or a subtle dry-brushing effect.
- Example: Creating a layer of dust on a larger model or adding a wash of color to a landscape.
3. Wet Application (with a Medium): Mixing pigments with a liquid medium, such as isopropyl alcohol or a pigment fixer, allows for more control and allows a wash-like application. This creates a more even, less textured finish. Note that some mediums may affect drying time or the final appearance.
- Example: Creating streaks of mud on a vehicle or blending pigments together for a custom color.
4. Layering: Applying pigments in multiple thin layers, allowing each layer to dry before applying the next, builds depth and dimension. This technique is commonly used in artistic applications.
- Example: Creating a realistic sunset effect or layering pigments to achieve a particular shade or color.
5. Pigment Fixers: Using a pigment fixer (a spray-on sealant) ensures the pigment adheres properly and prevents it from dusting or rubbing off. Not all pigments require a fixer; some techniques, such as wet application with alcohol, already provide a degree of adhesion. There are many types of fixers available, so experimenting may be necessary to find a suitable option.
- Example: Sealing pigments on a model after weathering to prevent the effects from being accidentally removed.
The choice of method will depend on the project and desired outcome. References indicate using a dry brush, dusting, and wet blending are common techniques. The addition of pigment fixers is recommended for permanence.
