Paul’s comment

The sun was much lower in the sky by now, and Nina explained this meant it was softer and more flattering for portraits. We still had our family under the shade of trees, and we sat them on a blanket in front of a patch of yellow buttercups. The long focal length and wide aperture has blurred these nicely, as well as the dark, contrasting green background behind. As Nina gave them direction and got them to smile in unison, I captured this winner!
