Final answer:
The full direct view in photography, especially relevant in health fields like dentistry, includes the extraoral frontal view with relaxed lips, providing a clear, natural representation of the patient's facial features.
Step-by-step explanation:
When taking photographs, the full direct view includes the extraoral frontal view, with the lips in a relaxed position. This typically means the subject's face is directly facing the camera, and the lips are not tensed, allowing for a clear view of the patient's facial features as they would naturally appear. It is essential for creating a baseline record in various health fields, including dentistry and orthodontics, where such images can be used for comparisons, treatment planning, and monitoring changes over time.
