Using ring flash for oral cavity photography

Obtaining high quality photographs of oral mucosal lesions is still a challenge. Appropriate Lighting illustrating the particular features of interests is an important component of oral cavity photography. One way to achieve better lighting for oral cavity photos is by attaching a ring flash. A ring flash is a strobe light that is shaped like a ring with its light coming from 100% on-axis. Since the light is coming from a bagel shaped source, they catch light it produces is bagelled as well. This flash comes with many benefits and is very easy to use for oral cavity photograph. It is useful for lesions localized in the palate buccal, the mucosa, and the mouth floor (Figure 2-4 supplemental). The ring flash can be placed on top of your digital single-lens reflex camera with the help of a hot shoe adapter, which will provide more control without having any effect on buttons.

获取高质量口腔黏膜病变照片仍是一项挑战。恰当的光照以突出特定感兴趣的特征是口腔摄影的重要组成。实现口腔照片更好光照的一种方法是通过附加环形闪光灯。环形闪光灯是一种形似环形且光线100%轴向发出的闪光灯。由于光线来自类似贝果形状的来源，它们捕捉到的光线也呈现出贝果形状。这种闪光灯具备众多优势，并且在使用口腔摄影时极为便捷。它适用于位于硬腭颊侧、黏膜以及口腔底部的病变（见图2-4补充）。环形闪光灯可借助热靴适配器放置在您的数码单反相机顶部，这将提供更多控制，而不会对按钮产生任何影响。
