I have realized that in cameras, specialized sensors help to target automatically. Those sensors with some surveillance cameras change in in the area of contrast, while others work with a beam of infra-red (IR) light, especially in low light. Higher standards cameras sometimes use a mix of both devices and may have Face Priority AF where the camera can ‘See’ your face as you concentrate only upon that. Many thanks for sharing your notions on this web site.
