Introduction. The use of digital photography has found its application in dentistry along with such diagnostic methods as computed tomography, myography, and radiography. Target. To increase the information content of the digital photography method in dental practice. Materials and methods. To conduct a full photographic examination, a digital camera and flash are required. The camera must have the following characteristics: compactness, high-resolution optical zoom, a fairly large screen, and autofocus. The most stringent requirements apply to the flash. Results. The larger the area of the light spot, the fewer shadows and highlights appear on glossy (wet) surfaces. When comparing the quality of photographs taken with a diffuser, the following results were obtained. Due to the larger diffuser, the flash produces a softer pattern in the base. The power of the modeling light (AF illuminator) is an important feature that helps the lens focus in low light conditions. Turning on the backlight speeds up autofocus speed and accuracy. However, not all flashes have a flash function. The use of a light diffuser allows you to evenly distribute the light over the subject. Conclusions. Thus, the use of a diffuser for ring flashes and camera illuminators ensures the achievement of the stated technical result: 1. Allows you to reduce the time spent on removing and installing the diffuser on the body of the ring flash or ring light of cameras; 2. Increases the clarity and detail of the resulting images. 3. Reduces the degree of distortion and prevents the appearance of image artifacts caused by glare.
