Together, the three artists began to revive the practice of painting en Plein-Air with pastels, as their teacher Lukits had done in the 1920s and 1930s.

From their training in the United States or in some cases Europe, they brought the tradition of working directly from nature or "en plein-air" as the French referred to it.

A well-heeled cosmopolitan with a home in Paris, and a Belgian wife, he spent the summers painting en plein-air along the coasts of Brittany and Normandy, and areas farther north.

Like the Parisian-trained painters of the last century, during the summers, Adams also began to paint "En plein-air" as the practice of painting out of doors, directly from the landscape is known.
