I have taken notice that in digital cameras, special
receptors help to target automatically. Those sensors with some video cameras change in in the
area of contrast, while others make use of a beam of infra-red (IR) light, particularly in low light.
Higher standards cameras sometimes use a combination of both models
and may have Face Priority AF where the photographic camera can 'See' a face and concentrate only in that.
Thanks for sharing your ideas on this website.
Does your website have a contact page? I'm having trouble locating it but, I'd like to send
you an email. I've got some creative ideas for your blog you might
be interested in hearing. Either way, great site and I look
forward to seeing it expand over time.
