I increased luminance and warmth by a very slight percentage. I pushed saturation by 3% and finally gave a last touch with Neat Image to clear the sky of the noise induced by the processings I had done.
I used Neat image. I adjusted the settings on the evaluation that 10% of the pixels in the sky were noise. I adjusted the level of reduction at 50% in both luminance and chrominance channels. I increased the sharpness by 20%.
What do you think of it?
