How to use your DSLR Camera as a Webcam In Linux
If you desire a more professional looking image when video conferencing, it turns out that you can use a Digital SLR camera as your webcam. Using a DSLR provides a number of benefits over an off-the-shelf webcam, most notably higher image quality, ability to finely adjust the frame of an image (zoom, wide angle), and adjust the depth of field. The depth of field adjustment is what allows for a nice, smooth, blurred background.
