Focus on The Bridge in Curve and explain the Background.
According to the National Gallery of Australia, Smith painted The Bridge in Curve, which is based on drawings made at Milsons Point on the North Shore, during an important phase of her career as an artist, when the importance of colour and the application of paint in small strokes gave her paintings a "brilliant vitality". Smith had become interested in colour theory and used this painting as an opportunity to demonstrate it with the blue and white of the sky contrasting with the more earthy colours of the buildings and vegetation.
