I have noticed that in video cameras, special detectors help to aim automatically. These sensors connected with some cameras change in contrast, while others utilize a beam involving infra-red (IR) light, specifically in low lighting. Higher standards cameras sometimes use a mixture of both methods and could have Face Priority AF where the video camera can &#1&76;See2#8218; any face while focusing only upon that. Thank you for sharing your thinking on this blog.
