Glass Shatter

ROLE
Act as a senior professional photo retoucher, image editor, photographer, compositing artist, VFX artist and AI image-editing specialist. Perform a controlled, production-quality transformation of the uploaded image. Treat the source photograph as the ground truth: preserve the human subject, recognizable identity, clothing, environment, composition and photographic characteristics while adding only the requested glass-shatter effect.

EDIT
Create a hyper-realistic glass-shatter breakout effect in which the main human subject appears to be breaking forward through a large transparent sheet of glass positioned between the subject and the camera. Add a concentrated fractured impact region, radiating cracks and three-dimensional broken glass fragments projecting toward and away from the camera. Preserve the original person and environment while integrating the glass using physically believable transparency, reflections, refraction, lighting, perspective and depth.

PRIMARY OBJECTIVE
Execute the requested "Glass Shatter Effect" convincingly and photorealistically. The finished image should look like a real transparent glass surface was positioned in front of the camera and fractured dramatically around the subject at the moment the photograph was captured.

The effect must have strong visual impact while preserving the person's identity and keeping the underlying photograph clearly recognizable. It should resemble a professionally executed practical/VFX composite rather than a generic broken-glass texture placed over the image.

EDITING PRIORITY
1. Preserve the human subject's exact recognizable identity and appearance.
2. Create a clearly readable shattered-glass breakout effect.
3. Establish convincing foreground depth using cracks and flying fragments.
4. Match glass reflections, refraction, lighting and perspective to the original photograph.
5. Preserve the original environment and avoid unnecessary scene changes.

GLASS SURFACE
- Introduce one large transparent glass plane between the camera and the photographed scene.
- Keep most of the glass optically transparent so the original photograph remains clearly visible.
- Use subtle physically believable reflections and refraction rather than a cloudy or opaque overlay.
- Match the glass plane to the camera perspective.
- Keep intact portions of the glass visually subtle.
- Allow the fractures and broken opening to communicate the presence of the glass.
- Preserve the brightness, color and detail of the underlying photograph through transparent regions.
- Do not tint the entire photograph.
- Do not blur or dim the entire scene behind the glass.
- Do not use frosted, smoked or opaque glass.
- Avoid making the glass resemble ice, plastic, crystal or a digital texture overlay.

SHATTER STRUCTURE
- Create one coherent concentrated impact region associated compositionally with the main subject.
- Build realistic major radial cracks extending outward from the impact region.
- Add irregular secondary branching fractures between the major cracks.
- Vary crack length, thickness, direction and branching naturally.
- Use physically plausible irregular fracture geometry.
- Keep individual cracks thin, sharp and detailed.
- Increase fracture density close to the primary impact area.
- Reduce fracture density progressively farther from the impact area.
- Create missing sections where glass has genuinely broken away.
- Maintain partially attached fragments around portions of the opening where physically plausible.
- Transition naturally from heavily fractured glass near the opening to mostly intact glass farther away.
- Avoid perfectly symmetrical spiderweb patterns.
- Avoid covering the entire frame with unnecessary fractures.
- Do not use a repetitive stock broken-glass pattern.

BREAKOUT OPENING
- Create a clear three-dimensional opening in the fractured glass around the main subject.
- Shape the opening irregularly according to natural glass fracture behavior.
- Use broken edges and remaining attached fragments to establish the thickness and position of the original glass plane.
- Keep the opening large enough for the subject's breakout effect to read immediately.
- Avoid making the opening a clean geometric circle, rectangle or artificial cutout.
- Keep fracture density strongest around the edges of the opening.
- Maintain believable structural continuity between the opening and surrounding cracks.

SUBJECT BREAKOUT EFFECT
- Make the subject appear to physically emerge forward through the fractured opening.
- Allow appropriate portions of the subject to pass visually in front of the glass plane.
- Keep the subject's face clearly visible and unobstructed.
- Preserve the original body position as closely as possible.
- Use the existing pose to determine the most believable breakout composition rather than forcing an unrelated action pose.
- Allow the head, shoulders, arms or other naturally appropriate regions to establish convincing foreground overlap where compositionally suitable.
- Keep glass fragments around the subject without embedding them unrealistically into skin or clothing.
- Maintain clean but natural occlusion around hair, shoulders, arms and clothing.
- Preserve fine hair strands where they overlap the fractured opening.
- The effect should suggest a captured instant of impact rather than a decorative broken-glass overlay.

FLYING GLASS FRAGMENTS
- Add a controlled number of three-dimensional glass shards around the fractured opening.
- Vary shard size, shape, orientation, rotation and distance from the camera.
- Include smaller fragments near the primary fracture.
- Include selected medium and larger fragments to establish dramatic depth.
- Allow several foreground fragments to project convincingly toward the camera.
- Allow other fragments to remain close to the original glass plane.
- Position some fragments between the camera and subject where they do not obscure important facial features.
- Give every shard realistic thickness and sharp fractured edges.
- Keep fragments transparent with physically believable reflection and refraction.
- Maintain irregular shard geometry consistent with broken glass.
- Do not create hundreds of random fragments that obscure the photograph.
- Do not distribute fragments evenly across the frame.
- Do not make shards resemble floating diamonds, crystals, metal or plastic.

FOREGROUND DEPTH
- Use selected glass fragments close to the camera to create strong three-dimensional depth.
- Establish clear foreground, subject-plane and background relationships.
- Apply depth of field according to the original camera characteristics.
- Extremely close fragments may become naturally defocused.
- Mid-distance fragments may remain partially sharp.
- Fragments close to the subject's focal plane should retain appropriate detail.
- Keep the subject's face as the primary visual focal point.
- Do not apply artificial radial blur to the entire image.
- Do not apply uniform motion blur to all shards.
- Preserve the original subject's facial sharpness and photographic detail.

GLASS OPTICS
- Render all glass as physically plausible transparent material.
- Use realistic specular reflections.
- Allow subtle environmental colors and highlights to appear naturally on shard surfaces.
- Use physically plausible refraction through angled or thicker fragments.
- Distort the underlying photograph only locally where it is viewed through angled glass.
- Maintain realistic transmission through intact transparent regions.
- Preserve believable highlight intensity according to the source lighting.
- Use restrained Fresnel-style reflectivity where physically appropriate.
- Keep edge highlights thin and natural.
- Avoid excessive chromatic aberration.
- Avoid rainbow-colored refraction.
- Avoid unrealistic mirror-like glass.
- Avoid glowing shard edges.
- Keep transparent regions optically clean.

LIGHTING & REFLECTIONS
- Match the original scene's light direction, intensity, softness and color temperature.
- Illuminate every glass fragment using the existing environmental lighting.
- Generate highlights only where each shard's orientation would realistically catch a light source.
- Reflect bright and dark regions of the environment naturally.
- Allow environmental colors to influence glass reflections subtly.
- Keep glass reflections subordinate to the human subject.
- Maintain realistic highlight roll-off.
- Do not introduce unrelated studio lighting.
- Do not introduce dramatic rim lighting.
- Do not create artificial glow around the subject or fragments.
- Preserve the original lighting on the person and environment.

SUBJECT PRESERVATION
- Keep the main human subject fully photorealistic.
- Preserve exact recognizable facial identity.
- Preserve facial structure, skin tone, expression and apparent age.
