  1. I have observed that in digital camera models, special sensors help to aim automatically. These sensors of some video cameras change in in the area of contrast, while others utilize a beam involving infra-red (IR) light, especially in low lighting. Higher specs cameras sometimes use a mixture of both models and probably have Face Priority AF where the dslr camera can ‘See’ a face and focus only in that. Many thanks for sharing your thinking on this blog.
