As a writer, one of the things we all learned from the movies was a kind of compression that didn’t exist before people were used to watching films. For instance, if you wanted to write a flashback in a novel, you once had to really contextualize it a lot, to set it up. Now, readers know exactly what you’re doing. Close-ups too. Writers can use filmic devices that we’ve all accepted so much that we don’t even see them as devices any more.
