What these were for

He made them for a classroom.

Karl Blossfeldt examining leaves, about 1894. Unknown photographer.

From 1899 Karl Blossfeldt taught “modelling from living plants” in Berlin, for 31 years. He picked the plants himself on field paths and railway embankments, photographed them, and projected the pictures on the wall for his students to draw.

He never meant them as art. When they came out as a book in 1928 he was 63, and famous almost overnight.

From the glass to the wall

  1. On the glass, at 1:1

    He photographed the plant at its real size on a glass negative, usually 9 × 12 or 13 × 18 cm. The plant lay on a sheet of glass, stood in plasticine or hung from wire.

  2. A section, enlarged

    In the darkroom he enlarged only a section of the plate. That is where the 12 to 45 times comes from, not the camera.

  3. Printed 30 × 24 cm

    Most prints were made on silver gelatin paper about 30 × 24 cm. Pegs and wire that showed on the negative were cropped away.

  4. Projected for the class

    For his students he made 9 × 12 cm lantern slides and projected them large. They drew and modelled from the wall.

Draw from the wall, like his students did.

One print is projected about two metres tall, as Blossfeldt did for his students. You draw it for two and a half hours, with one short break. Someone from the room explains the plant at the start, then it is quiet.
