True or False: An image exhibiting vignetting appears dim around its edges.

1. True

2. False

3. N/A

4. Only under specific conditions

The correct answer is: True

The assertion that an image exhibiting vignetting appears dim around its edges is indeed true. Vignetting refers to the gradual shading or dimming of an image, particularly noticeable at the corners or edges, compared to the center. This phenomenon can occur due to various factors, including lens design, aperture settings, or improper alignment of the imaging system. In radiography, this can impact the quality of the image and the interpretation of diagnostic information. Thus, identifying vignetting is essential for ensuring accurate imaging results and minimizing potential misinterpretations.
