The two images are similar because they both use the chiaroscuro technique.
The chiaroscuro technique is an artistic method that uses strong contrasts between light and dark to create a sense of volume and three-dimensionality in two-dimensional art forms. The term "chiaroscuro" comes from the Italian words "chiaro," meaning clear or light, and "scuro," meaning dark or obscure.
Artists renowned for their mastery of chiaroscuro include Caravaggio, Rembrandt, and Leonardo da Vinci. Caravaggio, in particular, was known for his dramatic use of light and dark in his paintings, influencing many Baroque artists who followed.
Overall, the chiaroscuro technique is a powerful tool that enhances the visual impact of art by manipulating light and shadow to create depth, drama, and atmosphere.
