I don't really care for the desaturated/washed out/faded look on those top photos.
I recognize that this is often classified as a "style", for some reason, but it just isn't one I particularly think is very good.
I will admit the same distaste for sun flare.
strictly personal taste mind you.
the bottom photos i find much more appealing.
the left is tightly framed, but nicely done. I like this one. her smile looks a bit forced, but when you work with kids, sometimes you just take what you can get when its close enough. I am getting the feeling that the color version of this one had pretty harsh lighting, but I like the processing on the conversion.
