Calatheas, or Prayer Plants, close their leaves up at night (looking like hands in prayer) and open them during the day. They are indoor loving plants who are quite finicky and need a lot of humidity. Many a plant-lover can regale you with stories of the many calatheas they have killed or who have succumbed to spider-mites.
The frequently changing weather caused huge changes in light – cloudy, raining, sunny.
Shot over 5 hours with natural light coming into the house. One photo every 5 minutes.
