It certainly looks too dark here, closer if viewed on Flickr. Shot straight into the sun even The 850's dynamic range wouldn't allow enough recovery of shadow detail in the field, and i hate a blown hightlight so it was a fight to get something. I thought maybe the green sunlit field back right might lift it but it's too small to do the job so? 4/10?I feel you need to let some more light in on that file, John?
