January, 2004. The images were taken in natural outdoor lighting condition. Brightness

and shutter speed were adjusted for each plot before acquiring images. During the

were required during bright daylight condition and lower shutter speeds were useful

during late afternoon to obtain good images with approximately unvarying brightness.
