2. Photographs

3. Subjective report

4. All of the above

The correct answer is: All of the above

Visual examination information can be recorded using various methods, including videotape recording, photographs, and subjective reports. Each of these methods serves a unique purpose in capturing visual data. Videotape recording allows for the dynamic observation of visual examinations, enabling detailed analysis of procedures over time. This is particularly useful in scenarios where movement or changes are a crucial aspect of the examination. Photographs provide a static visual record that can be reviewed later. They are particularly valuable for documenting specific visual characteristics, conditions, or changes that may occur over time. Visual documentation through photographs also aids in comparative analysis during follow-up examinations. Subjective reports encompass the personal observations and interpretations made by the examiner based on their expertise and experience. These reports can capture nuances that may not be fully conveyed through visual media alone, adding qualitative insights to the examination process. Since visual examination practices often involve a combination of these methods to create a comprehensive understanding of the subject being examined, indicating that all of these recording methods can be used reinforces the idea that each has its own strengths and contributions to effective visual testing.
