Where did Rembrandt van Rijn learn to chiaroscuro?

Rembrandt van Rijn learned chiaroscuro, the technique of using strong contrasts between light and dark, during his apprenticeship with painter Jacob van Swanenburgh in Leiden. He further developed his skills while studying works by Caravaggio and other artists in Amsterdam, where the dramatic use of light and shadow was prominent. This mastery became a hallmark of his own painting style, allowing him to create depth and emotional intensity in his works.
