Easy Lighting Setup
You do not have to start with a fancy setup and a lot of lights, but you need to understand what do you want to achieve and feel when lighting a character, object or environment.
Is a standard method used in visual media such as theatre, video, film, still photography and computer-generated imagery. By using three separate positions, the photographer can illuminate the shot’s subject (such as a person) however desired, while also controlling (or eliminating entirely) the shading and shadows produced by direct lighting.
You can apply these techniques and lighting setup to your 3d scenes. This will make your lighting more professional and simple to apply.
Next you will find a presentation that will explain the more basic principles of this lighting setup.
