Framing: Framing is boxing in a character or a few characters within the environment of what you are shooting, creating a sense of captivity or making the shot more visually appealing.
Deep Focus: Deep Focus is where everything in shot can be seen, there is no restrictions on what is in focus and what is blurred. This means that you can see everything going on around the character, not just the character themselves. This usually means that everything going on around the character is important or there is something to look out for in the environment not just on the character.
Shallow Focus: Shallow Focus is when only one specific object or character in shot is in focus and everything around them is blurred, thus focusing all attention on the character or object and highlighting that they are the most important or interesting thing on-screen. It can also be used to convey a sense of captivity like framing or to show that the character is self-centered or out-of-place.
Focus Pull: This is when you are in shallow focus and then you pull over to something else in shot that was blurred and use shallow focus on that. This is useful as you can redirect the focus of the audience without changing shot.
Depth Of Field: This is like focus only instead of how blurred or clear something is draws the audience’s attention to it this is the amount of light and other things in the background that draw your attention to the character or object.
Rule Of Thirds: Rule of thirds is where the character or object in focus is on the 3rd quarter of the shot instead of in the middle. This means that the audience can see things in the environment as well but not as well as they would if they were in deep focus. This also makes the shot appear more visually appealing which is why is it used often in photography as well as in the film industry.
