How do i use my digital camera for a webcam?

ma camera is D*3500... how can i use it as a webcam

You have to have software to do this, If the camera was designed to double as a web cam then you should have the CD with the camera when you bought it, if it was not meant to be a web-cam then there is nothing you can do, look on the web under the name of your camera, you might find something

Have a look in the instructions or on their website !!
