Love love love them! When I lived near Santa Cruz, they were growing around our property and I would think how amazing it would be to have an entire hillside of Calla Lilies. I saw one over at the coast on Saturday and played around a little in Lightroom with Split Toning. How do you feel about a pink Calla Lily? Of course white is the best, but isn't pink the next best?
P.S. Updated this posting to clarify. This is a white Calla Lily which I turned pink in Lightroom with Split Toning which allows you to change hue and saturation on highlights and shadows separately.
