Can a digital camera be doubled up as a WebCam by connecting it to ur PC?

I heard somewhere u can use ur didtal camera as ur webcam too. Is it true? My decision to purchase a digital camera may depend on this! Plese advise!

no, it won't. Many cameras do not support anykind of software that allows them to act as a webcam. I am sure of this, as i had the same question as you, and i wanted a camera that could be a standard digital camera (3,4,5 megapixels) and a webcam, but unfortunatly such a thing does not exist. The only way that you could have both, is that you could go buy one of those fake digital cameras for children. they can be both a digital camera (although a very very poor quality one- with no zoom) and a webcam. UNfortunaly, there is no camera that is a webcam and a decent digital camera.

Yes, you can. The camera usually comes with corresponding software...

i did it yesterday
