Webcam.

A webcam workflow begins with a live source and a person's decision to share it. That makes acquisition, preview, capture, submission, and stopping distinct states worth designing explicitly. In a browser, permissions and the delivered media settings shape what is available. A requested resolution is something to verify, and an unanswered permission prompt is different from a failed camera. The captured image also needs a clear relationship to the preview, especially when the preview is mirrored for a more familiar experience.

The guide collected here follows a webcam frame from user action to a reviewable result. Focus on device changes, denied access, orientation, and the point where a visible image is actually saved or transmitted. The camera frame overview connects this route with recorded-camera workflows. Test with readable text in view, then deliberately stop or disconnect the source. Those simple checks reveal lifecycle and orientation mistakes that a successful first capture can easily conceal.
