And this becomes very obvious when you manipulate the files in post processing.

Any kind of extreme manipulation will cause the sky to become grainy/ textured. Because of the limited dynamic range, extreme manipulation may be unavoidable in some cases.

I have newer versions of the images below, processed differently with more subdued tones, nevertheless the grain is apparent in higher res.

I've read somewhere that compared to the older 12MP sensor, the G3's sensor has less noise at high ISO, but more in low ISO. Haven't really looked into this but it may true. Augmenting the base ISO from 100 to 160 may have to do with it.

Well, the 12MP sensor at ISO 100 was okayish. But that mode is gone, and while it can be sort of emulated through overexposing ISO 200, differences in metering make that a fairly unhelpful approach.

I can live with it, your mileage may vary.

Thanks. Nice shots!
