Question

In aquatint, the depth of tone is controlled by:

• A. The amount of time the plate is kept in the open.
• B. The amount of water droplets on the plate after cleaning.
• C. The thickness of the etching plate.
• D. The fineness of the rosin dust and the length of time the plate is exposed to acid.

Hint:

Rosin dust and exposure time is key.

Answer 1

The Correct Option is D

The depth of tone in aquatint is controlled by the size of the rosin particles and the duration of acid exposure. Finer rosin dust results in smoother, lighter tones, while longer acid exposure deepens the tonal values.

• Rosin particle size: Smaller particles create lighter and smoother tones.
• Acid exposure duration: Prolonged exposure results in deeper tonal values.
• Control factors: Both rosin size and acid timing are key to achieving desired tonal effects.
