Teachers and avid hikers, Krystina Castella and Brian Boyl focus on letters in their book of photographs, "Discovering Nature's Alphabet."
While hiking with their cameras, the husband and wife came up with a game — to find and photograph as many natural objects shaped like letters. It took them five years and many retakes, but they have chosen the best from some 3,000 photographs and placed them in their first book.
Heyday Books of Berkeley, a nonprofit publisher that supports California artists and culture, published it.
The Glendale couple will conduct book signings and story-time events over the next few months at local bookstores. Storyopolis, a children's bookstore and art gallery in Studio City, has framed lithographs of photographs from the book on its walls, said Courtney Collins, the store's art director.
