When I increase the aperture my screen goes way darker! Please help!

Hey there!

I'm trying to get my shot in f22, so that everything is in focus, my shot becomes almost black.

The higher the aperture, the darker the screen goes, and vice versa. How would I change it so that when I shoot/film in a high aperture (22) I'm able to get a brighter picture/video/shot?

Please help Thanks!
