I disagree, the shot looks awful 'cos of it, the image totally suffers without any refinement of the noise, if that is possible. The noise is massive and obstructive.
I'm curious why it's so noisy? It was shot at ISO 100 and there is no way that properly exposed photo from GX100 would be so noisy at ISO100. So my guess is it was heavily underexposed, shot in JPEG with contrast to -2 or both?
