Jiaowai Dual Visual Poster Prompt

Based on the photo I uploaded, create a standalone 3:4 vertical 'Out-of-Focus Detached Twin' visual poster.

The image is strictly divided into two areas, upper and lower, with a height ratio of 1:1, each occupying 50%.

Upper and lower parts must maintain:

Same subject, same face, same action, same pose, same gaze direction, same subject position, same scene, same shooting angle, same compositional relationship.

Do not redesign the person.

Do not change the background.

Do not alter the photo content.

Upper Part | REAL

Fully preserve the original uploaded photo.

Maintain the texture of original mobile photography, digital camera, or life snapshots.

Retain all person, background, and environmental information.

Light exposure and color adjustments are allowed, but do not change the depth of field relationship.

Allow viewers to clearly see the original real state of the photo.

Lower Part | 85MM F/1.2

Strictly based on the same image as the upper part, re-simulate a professional full-frame wide-aperture portrait photography session.

Simulate:

85mm full-frame prime lens, f/1.2 aperture.

Subject's eyes, face, and main contours remain high-definition sharp.

Recalculate depth of field based on real spatial distances.

The focal plane where the subject is located is clear.

Environments before and after the subject gradually enter defocus status according to distance.

Close-range background retains some structure.

Mid-range background begins to soften.

Far-range background completely transforms into natural creamy out-of-focus (bokeh).

Background elements like:

Street lamps, car lights, shop windows, leaf reflections, metal reflections, sunlight highlights

Naturally transform into real optical bokeh of different sizes and blur levels.

The out-of-focus area must have real lens characteristics:

Soft circular light spots, slight cat-eye deformation at edges, highlight gradients, foreground/background depth layers, real spatial compression.

No artificial cutout feeling should appear at the edges of hair, shoulders, and clothes.

Natural transition is needed between hair strands and the out-of-focus area.

Retain slight lens breathing, chromatic aberration, grain, exposure errors, and real photographic defects.

The final effect must look like:

The same photographer did not move position, just swapped a regular phone for an 85mm F1.2 professional lens and took another shot.

Prohibited:

Whole-block background Gaussian blur.

Prohibit background becoming a mass of color without spatial hierarchy.

Prohibit cutting out the person and pasting onto a blurred background.

Prohibit face swapping.

Prohibit changing person's actions.

Prohibit adding non-existent buildings or scenery.

Prohibit illustration feel.

Prohibit excessive skin smoothing.

Prohibit plastic skin.

Prohibit AI studio photography feel.
