Monochrome art refers to artwork that is created using only one color or shades of one color. Positive space in art refers to the area occupied by the subject of the artwork, while negative space refers to the area around the subject.
Regarding ingredients or materials, there are various materials that artists use to create monochrome art, such as charcoal, graphite, ink, and paint. The specific materials used depend on the artists preference and the desired effect. For example, an artist may use watercolor paint to create a monochromatic painting with a soft, flowing effect, or they may use acrylic paint to create a more textured and layered effect.
In terms of toning black and white photographs, there are various organic materials that can be used, such as coffee, tea, and food coloring. These materials can be used to create a range of tones and effects on the photograph, such as sepia or a warm brown tone. However, its important to note that organic materials may not provide long-term protection for the photograph and may not be the best choice for important prints.
Overall, the materials and ingredients used in art depend on the artists preference and the desired effect, and there are various options available for creating monochrome art and toning black and white photographs.
