A dermal imaging system coordinates operation of an illumination unit, one or more lenses, and a camera to capture a sequence of images of an area of interest on a skin surface. The system automatically tags each image in the sequence of images. The tag for each image identifies a light source, an illumination angle, and a filter selected for capturing the image. The system automatically selects at least one image from the sequence of images, and analyzes the selected image from the sequence of images to provide a recommended skin disease diagnosis.
