Creating Instructional Video: Principles of Picture and Sound in Production

Introduction Composition and Lighting Sound Principles

Introduction

This article will go over picture and sound properties and provide techniques to manipulate them so that your video looks good and your audio sounds good. Whether working with a professional in a studio, or on your laptop at home, when you capture "video" you are actually recording two main elements - light and sound. Light and sound are physical waves that are then interpreted and digitized into information stored on a CPU. They both can:

  • be diffused and shaped by physical objects
  • be reflected on surfaces
  • lose their proximity power exponentially  

Because sound and light have physical properties that means that your computer, your furniture, and lamps can be moved around to improve quality, and you can try different configurations to get better results!

Lastly, if you record light and sound when they are too loud or too bright ("hot"), your CPU will make errors and the quality of your end product will suffer. On the other hand if your light or sound are too weak, the capturing device won't get enough signal and you will get visual and/or sound noise. Sometimes this can be fixed by just moving closer or further from the lamp or microphone. Let's jump into some suggestions!rainbow lightwave spectrum
