A conceptual storyboard is used to develop the basic visual
ideas such as the actions of the characters, camera positions, timing of
motions, and transitions between shots/scenes. Conceptual storyboards are
often loose, sketchy, and informal.
A presentation storyboard is used to show a detailed visual summary of the project to individuals with a decision-making authority, such as clients or supervisors. Presentation storyboards are often with details in color.
Your drawing frames should have a 3:4 aspect ratio; however, when you are showing camera moves you may use non-3:4 aspect ratio for drawing frames. You can use arrows to show the direction of action.
