I found using raw files and auto-bracketing aperture exposures by 1/3 stop increments based on the in-camera meter works very well. I just delete the inferior exposures in post-production.
When time is of the essence I simply take advantage of my camera's psuedo-ISO invariance. I pick the required shutter time and aperture and adjust the image brightness in post-production. This works well except for when the light level at least EV(100) 5-6. In very low ambient light in-camera ISO gain helps with read noise. There are two disadvantages. In low light in-camera review is impractical and in bright light you do have watch the in-camera meter to avoid sensor overexposure.
1. I use "Multi" meter mode with X-Pro 2 and X-100T.
“Basically, I mean, ah—well, let’s say that for me anyway when a photograph is interesting, it’s interesting because of the kind of photographic problem it states—which has to do with the . . . contest between content and form.
