Albert Renger-Patzsch, Foxglove (Fingerhut), 1922

The photographer may have been interested in capturing shape, pattern, and tone.
If I were the photographer I would call it “Tulip-like Flowers” because the flowers are the main focus, and they seem to look like tulips.
There aren’t straight lines in this photo, it is very organic and curvy due to the natural shape of the flower.
Similarly, the shape is very curvy and organic.
The pattern is shown through the repetition of the flowers and the dots on the flowers.
The texture would feel smooth due to the petals, yet bumpy as a whole due to the cup-like shape of the flowers.
The tone is most evidently shown through the color of the petals, in which some areas are darker than others.
The flowers that are closest to the camera are the clearest, while the flowers that are toward the black are slightly blurry.
