[Note to language buffs / grammar boffins: The use of adjectives in the title is questionable, except for fast, a legit flat adverb. Chalk it up to Confusingly Corrupted Headline Grammar.]
Comics are a visual medium for storytelling like movies or TV shows, but they differ from those in some important aspects. For one thing, they are even more visual, because there is neither sound nor music, which are often used to great effect on the screen.
But there is also a purely visual difference that comes from what I call the self-adjusted reading speed effect. When scanning the comic page for page, panel for panel, the reader goes ahead at his/her own speed, unconsciously adjusting for the time needed to comprehend the full information presented, which will differ depending of the size, complexity, and richness of detail of each panel.
This effect makes it impossible to use time in the same way as movies and TV shows do it:
- Showing the approach of an enemy as fast, indicating imminent threat, or slow, indicating looming danger.
- Forcing the viewer to watch, for a predetermined time, a scene where little happens, where there is no or only regular movement, e.g. a person walking down an empty street.
This does not happen in a comic the same way; if the creator e.g. uses many identical panels to indicate passage of time, the reader may get the meaning, but won’t experience the time, because the eye scans quickly over multiple identical panels. Panel size and page layout (e.g. overlays) are used instead to convey both timing and the associated meaning.
Note: My description of the self-adjusted reading speed effect is in disagreement with expert opinion: “Time will slow down with more panels because the reader’s eye will typically linger over the panels at the same rate.” I think this disagreement is in degree rather than in absolutes, though.
The self-adjusted reading speed effect is quite important, in my opinion: The decoupling of visual complexity and perceived speed of action allow comic creators wonderful freedom to use great visual effects without constraining other variables of storytelling.
Now this last sentence is probably impossible to understand without some examples.
You can read up these webcomics now if you want to avoid SPOILERS; there will be few major ones anyway, because I don’t refer to the plot much in this post.
