They're intentionally processed in part to indeed give a uniformity to all the images regardless of the camera they're shot with - so thanks for noticing! I suppose some like it and some don't, but isn't that the way it always is with PP? I enjoy the look obviously. It's basically done by adjusting the ends of the tone curve to fade out the shadows and then tweaking the luminance and saturation sliders among some other more selective sharpening and toning work. However, admittedly many of my photos (though not this one) are indeed shot through windows. Outdoors I tend to always shoot with a polarizer as I like the control over reflections and color saturation it gives.
