For Roelofs and other artists of the Hague School, with their knowledge of Dutch 17th-century art and the Barbizon School, plain air painting became fundamental. Taking Daubigny's floating studio as their model, Roelofs and Weissenbruch regularly went out in boats. Roelofs's pasture, windmill and canal landscapes - of which Summertime is a fine example - use lighting effects that express a painterly freedom comparable with Daubigny's.
