The adjuster should take as many photographs as necessary to depict the damage, including pre-existing damage. It is just as important to photograph undamaged property.
The photos must be of sufficient quality to see damage or lack of damage. Blurry, out-of-focus photographs and photos taken at night are not acceptable.
Further, the photographs must be adequately labeled, including the date the photograph was taken, the room location, and description of the damages being depicted.
