Selected from Callahan’s extensive work in this genre, the twelve intimately scaled prints in the exhibition were assembled into a special series by the artist in the early 1990s. Over the years, Callahan printed his pictures in various sizes but, after he had time to reflect on the presentation of this body of work, determined that this was the size in which he would like the photographs to be seen. Over the course of a career that spanned six decades, Callahan made nature one his primary themes, continually finding new ways of seeing trees, weeds, snow, and surf. Ranging in date from 1941 to 1991, the images in the exhibition typify the artist’s innovative approach to these subjects as well as his stated desire to “capture a moment that people can’t always see.” A number of works, for example, provide a striking description of surface detail on natural forms, while others reduce those forms into compelling abstract patterns and linear rhythms. Also remarkable in this group is the elegant union of textures and contours created in Eleanor, Aix-en-Provence, France, 1958, which superimposes the nude silhouette of the artist’s wife onto a deep landscape background. Consistent throughout the series are the simplicity and technical refinement that distinguish Callahan’s style and secure his place among the foremost American photographers of the 20th century.
