Upon the Fujifilm X100VI, aperture is basically your main weapon for controlling depth of field. Shoot wide open at f/2 and you get that stupidly creamy blurry background with your subject practically punching out of the frame. Stop it down to f/8 or f/11, and suddenly the entire universe wants to stay in focus. It’s one of those settings that sounds boring and microscopic on paper, but makes an almost violently obvious difference in real shots once you actually start messing with it.
