Creating areas of light and shadow are no problem with DaVinci Resolve. PowerWindows, polygons, or curves can be a colorist's best friend when controlling where you want areas of contrast. The only thing that limits you is the simplicity of the shapes.
When shooting on set, a pattern or "gobo" can be placed in front of a light source to create shapes. We can use the same technique in Resolve by using external mattes. In this tutorial I will show how to create more intricate shadows or highlights that can make your images more moody or suggest location.

Just a very quick tip for Blackmagic Da Vinci Resolve: How to do supers and titles. Resolve is an amazing grading program - and the lite version is FREE but still super functional. But isn't really a finishing program - like smoke or even FCP. This little tip is about closing the gap a little. Hopefully you find it useful! blackmagic-design.com/products/davinciresolve/
