I've really gotten used to my best way of shooting with this camera. I bought the X100s about a week ago and love it.
How I Shoot With It
I shoot primarily on aperture priority mode with Auto ISO from ISO 400 to 3200. I have a few different custom settings. One is minimum 1/125th shutter speed (the fastest minimum you can set). The second custom setting is 1/60th for low light. I use ISO 400 minimum to give me a faster shutter speed by default and it also increases highlight headroom by a stop.
I shoot OVF only and turn off the main display and rarely if ever use the EVF.
Also, I love that you can play back your photos through the EVF. It feels like I'm looking through some sort of slide projector!
How I Process The Files
I shoot to raw but with a B&W preview with soft highlights and hard shadows. Then when I'm importing into Lightroom, I import directly with the VSCO Film 01 Ilford HP5 preset applied. I might adjust the exposure by a notch here and there and then the ones I like are published on my blog.
Sometimes I go back and see what colour versions look like but this is ultimately a B&W digital film camera for me. While the SOOC images are fine, I really dislike the clinical "perfect" feel of digital camera images for my personal pictures, which is why I use VSCO Film 01 on all my files out of this camera. I find VSCO's Ilford HP5 preset brings out the best tones of the colour raw files, especially with people.
Things That Could Be Improved
I don't like that when I half press the shutter both the AF and the AE meter/focus and lock. I would much rather the auto exposure continue to adjust after focus is locked. I was shooting to my left from the hip yesterday and focused on the wall at about f5.6 but the exposure locked on the dark wall, not the subject I was about to walk past and was about 2-3 stops overexposed and unusable
🙁
For what I shoot and the way I shoot I can't really fault much else!
