An electronic calculator with trigonometric functions can be used to compute times of sunrise, sunset, or twilight, or time of desired illumination at any location in mountainous terrain. The method is more convenient and versatile, and less cumbersome than using tables. Latitude, longitude, elevation, day of the year (1 to 366), and slope to the horizon at the azimuth of the sun at sunrise and sunset are necessary for the computations. The effects of elevation of the observation point and blocking of the sun's radiation by terrain surrounding tlie observation point are included in the computations.

For the past several years, photographer, screenwriter, and author Bill Wittliff has been placing photographic paper inside beer cans, tubes made of PVC, and other cylindrical containers and affixing them to posts, trees, and other vertical supports on his Plum Creek Ranch near Luling, Texas. Wittliff pokes pinholes in the containers and allows the sun to “paint” on the paper over periods that can last anywhere from a few days to a year. The resulting solargraphs are, as art photographer Kate Breakey suggests, a record of “the slow turning of the earth, without the details: the gradual passing of time at Plum Creek.” In SunriseSunset: Solargraphs from Plum Creek, this relentlessly inventive writer and artist has gathered some of his favorite creations, offering them as a visual tribute to the interaction of a particular place within the great arc of the cosmos. He shares with readers his delight upon discovering the technique through a chance encounter. He confesses an infectious enthusiasm for harvesting such unpredictable products of light and time as he roams with his canine companion Louie across a locale he describes as “a continuous miracle. . . . I want to see new worlds on a piece of paper . . . I want to be astonished . . . I’m always greedy for another miracle.” Kate Breakey’s foreword sets an affectionate, thoughtful tone for this stirring artwork, followed by the literary observations of photographer, educator, and artist Keith Carter. But the bulk of SunriseSunset is given over to page after page of mysterious, other-worldly, evocative images etched by “the slow turning of the earth” and the fertile imagination of the author.

Much like life, the stage changes even when our vantage point doesnt. And so it is with the rising and setting sun, no two are ever the same. Every picture tells another color, shape and shadow story . . .
