It was blowing cold and about 15 degrees for this shot, so we didn't tarry and only got the one really usable shot out of the 30 or so taken. Lit with sunlight filtered through the trees behind me and over my left shoulder. No reflector was needed, because the snow did nicely to provide a nice all around soft fill.
First I used LightZone for Linux to do the RAW conversion and relight the image, reducing the shadows on her face and add a high-key effect. Then I used Gimp to do a bit of reconstruction of her hair due to some wild strands blowing in the wind, and softened up her skintone and brightened her eyes. I also prefer to use Gimp for the final image sharpening.
