The excellent quality of the X100S’s in-camera JPEG processing means that for many purposes it makes perfect sense to shoot JPEG+RAW with the intent of using the JPEG by default, and only resorting to the Raws when you want to pay an image special attention, as in the examples above. The most obvious case when you’d need the extra latitude of a Raw file is when you want to adjust white balance post-capture.
This is exactly how I shoot with it, and I’ve found it to work really well. If an image doesn’t have some quality I’m looking for and some minor adjustements to the jpg don’t give it to me (Lightroom can do a lot with a jpg!), I work up the raw file and see how it goes.
On dynamic range:
An alternative way of thinking about this is that DR200 is like underexposing a stop to retain highlights then adjusting the brightness afterwards, and DR400 is like underexposing by two stops and adjusting further. Because of this, the minimum ISO available in each mode is limited: ISO 400 at DR200, and ISO 800 at DR400. The flipside to this approach is shown by ISO 100, which is effectively the opposite; i.e. ISO200 overexposed by a stop then pulled-down in processing. This results in the loss of stop of highlight range - to all intents and purposes it counts as DR50, and should therefore normally be avoided. (Note ISO 100 is only available in JPEG anyway).
As usual for DPR, this is a detailed review that can teach someone already using the camera a lot about how it’s put together, what its capabilities are, and how to get the most from it.
Between ISO 200 and 800 the X100S delivers images which contain effectively no visible noise. This, coupled with the inclusion of a 3-stop ND filter means that it is entirely possible to shoot at ISO 800 outdoors in bright daylight for the sake of better dynamic range (see DR expansion modes section on the next page). In our everyday shooting we alternate between DR200% and 400% in especially tricky conditions, and we’ve learned not to worry about the consequent increase in ‘base’ ISO.
I had a great evening at the best pizza place around this weekend — got a few photos I enjoy, too.
