Just found this website Fuel Your Motionography which is a great place to find new videos but also to find explanations for the terms that are associated with cinematography.
If you want to broaden your understanding or are a little confused with some of the terms, this website gives fantastic examples and good descriptions for each term relating to cinematography.
