Got it. I think the Focus S won every single time, which is unfortunate because I bought a Lumia 900.
I can only guess that the trees in the outdoor photos were green and not the yellow that the Lumia 900 showed?
I'm pretty sure that on the Lumia 900's Photo #1 the lens was not wiped off or had some fingerprints or something on it because the pictures looks terrible.
It's very hard to tell without knowing the actual color of the grass and trees in your photos. I also noticed that with both #1 pictures something very odd is going on with blurriness. It looks like there are squares of blur in the grass.
