Ahh I see thanks for that
Glad its noise as I can deal with that
Will redo them with noise removal for the sky
I,ve not noticed this before but I dont do that much landscapes mainly macro , I guess blue sky is more prone to noise than the green backgrounds that I normally have
Yes, blue sky is problem for many cams. Its because red and blue channels are always weaker than green. In case of 7D red is weakest (sorta normal for Canon) and blue needs to be boosted about 150% to match green under daylight (at least thats what DxOmark says). Its different under different lights. As light in this scene was probably quite cold, it might caused slightly worse performance (winter blue sky scenery is usually harder than summer one on camera).
Add to that fact that its simply bit noisy camera and it can now and then produce this.
