Diffuse illumination is the best choice for photographing external eye structures because it provides a soft, even light that minimizes harsh shadows and highlights. This type of illumination allows for an unobstructed view of the surface of the eye, which is essential for capturing detailed features like the cornea and conjunctiva. By spreading light broadly, diffuse illumination enhances visibility and contrast without creating the glare that can obscure fine details.

In the context of external eye photography, having a clear representation of the eye's anatomy is crucial for accurate assessment and documentation. While other techniques, such as retroillumination, serve specific purposes in evaluating features located deeper in the eye or identifying abnormalities, diffuse illumination excels at illuminating the external structures in a way that is most effective for detailed imaging.
