A portrait must take the measure of its subject. For two weeks, Galapagos Naturalist and Guide Bitinia Espinoza not only gave our group of travelers an amazing insight into what we were seeing, but also putting that knowledge into a context that helped us to see more than just plants and creatures, but also an entire ecosystem at work. In addition, she had to provide leadership as a guide, as well as keep us on schedule and safe from harm on both land, and for those snorkeled, under the water as well. A daunting task -- yet with more than 20 years of experience guiding groups, Bitinia seemed to handle it effortlessly. I wanted very much to make a portrait of her somewhere along the way that would speak of her character, personality, and capabilities. I had my chance while having lunch at the El Chato plantation in the highlands of Santa Cruz Island. She was sitting at the next table, and conversing with one of our trip members. The soft light was playing across the front of her face, bringing both a warm glow and strength to her features. Her naturalists hat defines her role, her blurred hand speaks of the energy that lies within, and her relaxed expression tells us that she seems comfortable in her own skin. I converted the image from color to black and white because I did not want the vivid colors in the background to compete with character I was trying to define. Bitinia works as a naturalist/guide in the Galapagos for some of the most respected travel organizations in the world, and this image offers a glimpse of the qualities she brings to her profession.
