Good webcam setups have a sharp depth of field, which makes the speaker look sharp and the background blurred. This requires auto-focus because a few centimetres matters to be in field.
- capableweb 4y ago> Good webcam setups have a sharp depth of field, which makes the speaker look sharp and the background blurred I'm guessing you mean "shallow depth of field" rather than "sharp" here. And you probably don't want it to be so shallow so a few centimeters would matter, then your nose could be in focus but your ears not, or vice-versa. That's a bit too shallow. It also doesn't require auto-focus, it requires you to be able to put the camera at a good distance with the correct f-stop, or being able to change the f-stop one way or another. Auto-focus is more for cases when the subject/object moves a lot forward/backward from the perspective of the camera, so you don't have to manually adjust things.
- henryackerman 4y agoI'd say auto-focus is a requirement for UX. Most users won't find the manual focus adjust button.
- RobotToaster 4y agoWhen taking portrait photos ideally you want the eyes to be perfectly in focus, and the nose and ears very slightly out of focus. I doubt a small sensor auto-focus camera will achieve that though.
