CONVENTIONS OF GRAPHIC NOVELS
Often the first page of a comic or graphic novel, a splash page, is a full page panel that is used to relate the setting, main characters, and to establish a mood or context for the narrative. Inset panels (such as the memory in the thought bubble) are sometimes used to convey another time or place.
Transitions are used to create different effects such as slowing down an event to mark its importance or to highlight a switch in perspective.
In this type of transition there is relatively little change that takes place between the panels. It is used to slow down an event and hightlight an important scene.
The actions of a single subject are shown through a series of progressive actions.
The action transitions between different subjects in the same scene, a common transition, paricularly for conversations between characters.
The action transports the reader across different times and spaces. It an be used to convey a flashback or a switch of perspective.
