yes, stop at ISO 800 on Nex C3

Gollywop: So I'm usually shooting at base ISO. When, however, shooting conditions do not allow me to ETTR [expose to the right, i.e. as much exposure as needed to get brightest parts of a scene recorded at 100% brightness], I set aperture and SS [shutter speed] as needed to achieve a maximum exposure value and then dial in ISO as needed up to my partial-ISO-invariant limit. In the case of my [Olympus] E-M5, that's ISO 800, and that looks to be the same for your C3. If further brightening is required, I shoot dark and apply it in processing.

Yes, all makes perfect sense now.
