It depends a lot on the state of your career and the particulars of your job. If you're hired to give them a spec script or do a first draft, you write it like a novel and not try to visualize it with camera angles. If you're a minor/major producer actually working with everyone else then you have a lot more say in the process.
For untested screenwriters your job is to prove you know how to tell a story and inspire a director on how to visualize it. The more clout you have, you can include specific camera angles for important scenes. But you never want to "direct" the story through the script, as that is the Directors job. They'll either ignore you or be actively annoyed by you.
The process has changed over time. Years ago some scripts basically read as a combination of a screenplay (the more "prose" centered script to sell to producers), shooting script (broken down into more vital components on how it will look on camera) and shot list (the different camera angles used in any given scene).

It's generally standard practice to not "direct from the inside." Unless you're a producer, it's seen as arrogant and kinda douchey.
"It's so hard to be humble, knowing how great I am."
The script tells the story. If there's a specific shot you want, you don't specify it, you emphasize what you want seen in the action description so the director chooses those shots. Describing exact shots is the director's job (or perhaps the cinematographer).
If you know you're going to be the one to direct it, you have more leeway to write down what you want as a reminder.
The example I was shown was the adrenaline shot scene in Pulp Fiction
. (search in the page for "push down on the plunger" and read until Mia wakes up). Each line of action describes one shot among a bunch of rapid cuts without saying "close-up of x".

There's the fulls cript including actions and dialouge and some camera angles. But can they didctate within the script how a camera functions and are they allowed to give titles to previously uncomposed tracks for a soundtrack?
I've seena few websites where they inform about scriptwriting and not all of them include the camera descriptions and instead just where the charcters are, what they say and what they do.
