1. A method of obtaining an image of an ocular feature comprising: providing a digital video camera; providing at least one processor in digital communication with the digital video camera; providing an illumination source which is controlled by the processor; providing an input source in digital communication with the processor; using the input source to define at least one selection criteria related to an anatomical ocular feature of interest, which selection criteria is stored in a memory in digital communication with the processor; capturing a first segment of one continuous video stream of sequential ocular images with the digital video camera, wherein the first segment of the one continuous video stream of sequential ocular images is captured at an initial illumination level provided by the illumination source and which illumination level is controlled by the processor; processing multiple ocular images of the first segment of the video stream with the processor to score the processed ocular images according to the selection criteria stored in the memory to select an individual ocular image from the first segment of the video stream which selected image is, according to the score determined by the processor, more likely to include the ocular feature of interest than other individual ocular images of the first segment of the video stream; and upon selection by the processor of an individual ocular image from the first segment of the video stream more likely to include the ocular feature of interest, controlling the illumination source with the processor to cause the illumination source to provide a second illumination level while capturing a second segment of the video stream of sequential ocular images, wherein the second illumination level is of a higher intensity than the initial illumination level.
