If you have a smartphone, you have a tool that can get you started in video blogging. Even if your smartphone is a few generations old, it will have a good video camera, and that is all you really need in order to start video blogging, podcasting, and more.
Don’t have a smartphone or don’t want to use it for video? Get a web cam. Your computer or tablet probably has one built in, or you can buy one. I have an inexpensive Logitech HD Pro Webcam C920
and it records high-quality video and audio. With your phone or web cam, you have a tool that can help you get started with video blogging and building your online audience.
