The plant

The leaves pictured are those of the Dogwood, Cornus sanguinea - Linneae, 1753.

The essential feature of this plant is the bright red color of the leaves in late summer and autumn. It is due to the presence of anthocyanin pigments, which are revealed when the leaves begin to wither and lose their chlorophyll.

The same phenomenon occurs for many plants, including in particular the vineyards boast exceptional color red in autumn. This effect is particularly dramatic.


The subject was relatively immobile, a sunny afternoon of autumn. The camera mode is set to aperture priority.

The photograph was taken with a zoom lens set to 300 mm focal length. With a sensitivity of iso-200 and an aperture of f / 8, the speed was 1 / 320 th of a second.
