METHODS—Photographs camera, film, and local knowledge of photo point location; given these, they are easy to set up and retake. Agencies can encourage participation by external groups or permittees by providing the photographer with film and development. Double prints allow the agency and photographer to keep copies of photographs for their files. Negatives should generally be kept and filed at the agency office. 7. Video Images Video cameras, i.e., camcorders, are now available and are able to record multiple images of landscapes for monitoring. While video images provide new ways to record landscape images, limitations in their use should also be considered. Video tapes, especially the quality of the image, may begin to deteriorate within 5 years. These images can be protected by conversion to digital computer images (expensive) or rerecording the original tape onto a new blank tape. Comparing repeat video images is difficult, especially if the same landscape sequences are not repeated in the same way on subsequent video recordings. Video cameras are also more susceptible to dust and heat damage and cost considerably more than 35-mm cameras. Advantages and disadvantages of video cameras should be carefully considered prior to implementing a video monitoring system. 8. Repeat Pictures When repeat pictures are taken, follow the same process used in taking the initial pictures. Include the same area and landmarks in the repeat general view pictures that were included in the initial pictures. Take repeat pictures at approximately the same time of year as the original pictures. 9. General Observations General observations concerning the sites on which photographs are taken can be important in interpreting the photos. Such factors as rodent use, insect infestation, animal concentration, fire, vandalism, and other site uses can have considerable impact on vegetation and soil resources. This information can be recorded on note paper or on study method forms themselves if the photographs are taken while collecting other monitoring data. 10.
