In a recent thread about EttR at LuLa, one of the techier posters mentioned that increasing ISO when shooting a CCD based camera won't yield an image much different than just underexposing it . Underexposing and adjusting in C1 will result in an image of about the same when processed correctly in C1, as opposed to boosting the data in camera with the ISO. This surprised me a little, but I've never really thought about it.
I've done a few tests, and anything larger than the 2.5 exposure adjustment limit gets challenging, but basically files can be processed to be virtually identical and possibly the ISO 35 shots, even though more than 2 stops underexposed might be yielding slightly cleaner files. Boosting in camera ISO does still provide better camera previews if you are reviewing them for composition or focus, and it certainly is faster to post process.
Just curious as to habits of those using MFDB. If you need a slightly faster shutter speed which will result in underexposure, do you boost the ISO or just shoot it?
