This image is a composite of two images. The couple’s image was taken during a post wedding couple shoot session. The background image was shot during a lovely evening few days prior to couple shoot.
With the idea in my mind, all I had to do was to create a silhouette with light colored background (white / grayish). So I took the couple to a shaded area and chose an angle from where background was bright. I asked the couple to stand probably about 4-6 feet from the light opening to make sure that light fall off kind of wraps around the couple.
Once the image was shot, I brought both the images in photoshop. Overlaid sky image layer over couple’s image and changed layer blending mode to “Multiply” and that it! The two images merged seamlessly.
