The photographic work of Mr. Chester F. Stiles, of Cambridge, was placed on exhibition yesterday under the auspices of the Camera Club. The exhibit consists of seventy-five winter scenes taken last month among the northern peaks of the White Mountains, together with a few summer scenes of the same localities which serve as contrast. The pictures were taken under peculiarly trying circumstances.

From the standpoint of photographic research the collection is valuable as an evidence that difficulties resulting from exceptional brightness, cold, and altitude can be successfully overcome. This was done by the use of a specially constructed camera provided with a long focus lens and isochromatic plates. Perhaps the best example in the collection of photographic achievement is a panoramic view showing Clay, Jefferson, Adams, and Madison Mountains as seen from the summit of Mr. Washington.

From an artistic point the pictures are valuable inasmuch as they give detailed and distant effects. Of these, "The Frost Work on Old Signal Station" and "Crawford Ridge from Mt. Washington" are especially interesting. The most striking picture in the entire collection, however, is a moonlight photograph of Adams and Jefferson Mountains, taken at midnight from Mt. Washington. In this picture a brilliant aurora, as well as electric lights in a town fifteen miles distant are clearly shown.

The exhibition will be open every day this week at the Brooks House from 10 a.m. until 9 p.m., with the exception of Wednesday and Friday, when the doors will be closed at 6 o'clock.
