30-DEGREE RULE

 The 30-DEGREE RULE states that if an editor cuts to the same character or object in another shot, the second shot must be positioned at least 30 degrees away from the first camera setup.


If the camera moves less than 30 degrees, the cut between shots can look like a JUMP CUT or a mistake. A jump cut happens when two shots are cut together, but the camera position doesn’t change much but the subject moves in the second shot (jumping around the frame), giving the impression that time has moved forward. This type of cut can be very jarring to the audience, making them notice the technical side of filmmaking instead of being focused on the story.


There is no guarantee that slavishly complying with the 30-degree rule will save you from the big bad jump cut. In spite of their common subject and shot scale, and despite shifting the viewing axis by more 30 degrees, this couple of shots simply don’t fit together. It just feels weird. So clearly, the 30-degree rule is not bulletproof, and a good rule of thumb might be: You never know until you try. So try, and simply discard the result if it doesn’t work and try a different combination of shots (like using a different shot scale, inserting another shot (i.e. an insert) in-between, or using an establishing shot or a moving shot instead).

PRINT RECOGNITION OF PRINTING PROCESSES

When viewing a printed sample it is often difficult to tell which process has been used simply by looking at it with the naked eye. However, if a printed sample of the text area is examined with the use of a magnifying glass, the following characteristics are visible.  • Clean edges around Lithographic print  • Outline edges around Flexographic/Letterpress print  • Dotted edges around Gravure print  • Coarse/dotted edges or clean edges around Screen print, depending on screen mesh used  It is undoubtedly a considerable asset to be able to determine with reasonable accuracy the printing process or processes by which an item of printed matter has been produced. There are a number of characteristics or clues which, if they can be discerned, make identification of the process possible, but not necessarily simple. Indeed, there are some jobs where it is very difficult to identify the relevant process or processes, even to those having considerable experience, and the...

180-Degree Rule

Establishing the Line of Action The 180-Degree Rule is a guideline in filmmaking for where it's best to place the camera when filming a scene, so that the audience doesn't get confused about the geographical relationship between the characters. The rule states that these characters should always have the exact same left and right relationship to each other in every camera setup. To establish the 180-degree line, draw an imaginary line from one character's nose to the other, that runs straight through the two characters (not between them). This imaginary line is called the Line of Action (also known as The Line, Axis of Action, or the 180-line.) Once you have a line of action established, you should only place the camera on one side of the line (left or right). Crossing the Line When the 180-Degree Rule is broken, it is called Crossing (or Jumping) The Line . This typically happens because the camera has moved across the Line of Action. Shots that have crossed the line c...
