I found this website to be extremely useful because it gives you 8 descriptive ways on how to shoot videos and make it look professional. I find this as an amateur film maker to be extremely useful due to the fact that I want my videos to look as professional as they possibly can.
The tip that I found to be the most useful was number 4 - this tip explains how to use lighting to your advantage in order to get clear and crisp shots of your subjects - I found this useful because I am going to be lowering certain lights in order to set a dark scene, therefore I must take lighting into consideration otherwise the subjects within my frame wont be very easy to see and will simply be sunken in with the background.
