Lovely shots lansky.
I'm curious - what PP are you doing, if at all? For example, the shot with the man selling ice cream : the colors are very vibrant, but the sky is very cloudy, there aren't even shadows on the ground as far as I can see.
I see this in quite a few GR shots, and I'd like to know if this is an in-camera setting, PP, or just the way it really was...
As the Ricoh shoots DNG I am using PS for very basic editing then finishing off in the Nik Colour Efex package as this allows a variety of options. It is easy to bring back sime sky details (providing it is there to start with) as you can do slective editing in Nik and as I already had Silver Efex pro, I got the whole package free as part of a promotional upgrade.
have to say though that the GR does deliver super clean DNG files to start with that need very little editing.
