This is one of the most important settings. There are a number of ideas for the best settings to use so it is a matter of working out what you prefer by testing different settings. One setting for one condition may not suit another.
The idea is to capture as much information from the initial footage from the camera so it can be used for better results in the post production stage of your editing. This will result in a flat looking un-saturated image, which looks unappealing but will have more detail in the shadows and highlights. This image will allow a better end result in post production.
