Danish artists Peter Ilsted (1861-1933) & Carl Holsøe (1863-1935) & Vilhelm Hammershøi (1864-1916 who was Ilsted's brother-in-law), formed the core of the Copenhagen Interior School. They portrayed scenes of everyday life inside houses. Ilsted, Hammershøi,& Holsoe's quiet rooms, delicate lighting - mostly by sunshine - usually focus on a single person. They use a limited palette with dull tones emphasising how the sunlight reflects on each surface giving them different textures. Some find the depictions calming & powerfully beautiful, others see the women inhabiting these spaces as lonely & waiting. All 3 artists were members of The Free Exhibition, a progressive art society created around 1890, famous for painting images of "Sunshine & Silent Rooms," all in subtle colors. Their works reflect the orderliness of a tranquil life, similar to the earlier works of Vermeer. These interiors evoke at once a sense of calm, as well as a sense of mystery.While at first glance their work appears similar, it is in fact quite different. Hammershoi's work has an aloof austerity, in contrast to Ilsted's scenes of common life. Ilsted was more of a technician, & he made considerable contributions in the field of graphic art. Ilstedes mezzotints were very popular & important in his day. Ilstedes achievements in mezzotints were revolutionary. Some of his mezzotints, most of which were created in black as well as color, are considered among the finest ever made.
