Visualization

No hypotheticals here - personal experience only please.

You either fall in one of three categories.

1) You've made movies and, therefore, have some kind of understanding of how words translate to cinematic image. Thus, this helps you create a more visual screenplay.

OR You haven't made movies AND

2) You've watched a movie AND read a corresponding screenplay. Thus, learned the visual aspect in this manner.

OR

3) You've not done 1 or 2. So, if you fall into this category, from your personal experience only, how do you know how to make your screenplay visual?

To clarify, for number 3, you can have watched movies and read screenplays, but not read the screenplay and watched the same movie, to determine how a screenplay is visualized.

I ask because I feel like there are some "aspiring screenwriters" that fall into category 3 and I wonder how they think they can write visually for cinema.
