Create a hauntingly beautiful double exposure photograph of a woman, with two distinct frames merged into one. In the first frame, capture the woman's back, shot in close-up, with a shallow depth of field that blurs her body, while the distant mountain range in the background is sharp and crystal clear. This frame should be rendered in black and white, with a subtle gradient filter to enhance the contrast and mood of the image. In the second frame, capture the woman's face, looking directly at the viewer, with a soft, ethereal light illuminating her features. This frame should be faded, with a subtle transparency that allows the black and white landscape to bleed through, creating a sense of layering and depth. The overall effect should be dreamlike and surreal, as if the woman is gazing out at the viewer from another realm. The photograph should be shot with a Canon EOS 5D Mark IV camera and a Canon EF 70-200mm f/2.8L IS III USM lens, with a focus point on the woman's face in the second frame, and a subtle blending of the two frames to create a seamless, double exposure effect.
