Hello, Cleary, 

By default, RadWebCam is automatically started. However, you can disable this option and initialize the camera with specific settings as it is demonstrated in the following help article: https://docs.telerik.com/devtools/winforms/controls/webcam/connect-to-camera-device

The RadWebCam.GetVideoFormats method will give you the available video formats for the specific device. 

Currently, the RadWebCam control is using the video feed and it takes a snapshot from it. Some cameras can produce a still image separate from the video stream. The still image usually gives a better quality of the picture, than the video stream.

It is a reasonable request to add support for using the still image capturing to get the snapshot when the camera allows this.

I have logged it in our feedback portal by making this thread public. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.

I have also updated your Telerik points. 

I hope this information helps. If you need any further assistance please don't hesitate to contact me. 

Regards,
Dess | Tech Support Engineer, Sr.
