The story behind the image starts with scouting areas. I am familiar with this large area called Big Meadows in Shenandoah National Park, Virginia. During the summer, the meadow is filled with various green and yellow colors. When a professional model who is also a good friend of mine visited me, I wanted to take a road trip and photograph her at Big Meadows. We discussed wardrobe and felt a white dress would work well with the field. My vision was to capture a lovely lady in a beautiful, open meadow. I made a watercolor painting of this photo too. We were lucky the park had minimal people and did not have to work around others. We did multiple looks and wardrobes while there, and I was able to obtain some great shots. The bottom line is as you travel to places, consider sites for future shoots.
I know the place! Walked along this field many times. It is one of my family favorite parks to visit. Background looks very painterly in your picture.
