So, how do you become the master of the camera you do have? Consider the phone that is next to you. It is a great little camera! Compact, fast and convenient.

I recommend this article from Eric Kim Photography, “How to take better photos on your phone.” In this article, you can get a lot of different pointers that help you even look at your photography differently as well as your camera on your phone as a capture tool.
