Impressionism seeks to capture light and color as perceived in the moment, without idealizing or manipulating them. To achieve this, artists used loose brushstrokes and vibrant colors, and painted outdoors to capture natural light.
The aim is not to represent reality objectively, but rather to capture the visual impression of the world around them, such as city walks, social gatherings, or natural landscapes.
They paint outdoors, that is, in the place where the scene takes place. This allows them to capture light and color more accurately, and also gives them greater freedom of movement and expression.
