Recently, I dove into a fascinating AI image generation challenge: replicating a high-difficulty pose from one image onto another character without altering the original identity. The goal was to perfectly align every joint and angle—from head tilt to finger bends—while keeping the camera perspective and composition exactly the same. The result was so precise it felt like magic.
This process involved using a tool called Nano Banana Pro, which lets you upload your original image and a reference pose, then apply a carefully crafted prompt to guide the AI. The prompt is incredibly detailed, enforcing strict constraints to make sure the pose matches the reference image point by point—head, shoulders, hips, knees, ankles, arms, wrists, and even fingers must align perfectly.
What blew me away was how the AI managed to keep the original character's unique features intact—facial shape, hairstyle, skin tone, clothing texture, and even style—while only changing the pose and camera angle. This meant no unwanted style blending or background shifts, which often plague AI-generated images.
Some key insights I learned:
- Precise skeleton alignment: The AI uses a “target skeleton” from the reference pose and redirects the original figure’s skeleton to match it, ensuring limb angles and torso twists are spot on.
- Priority matching: The system prioritizes aligning the pelvis and center of gravity first, then the torso and shoulders, followed by hands and feet, and finally fine-tunes finger positions and subtle expressions.
- Minimal error tolerance: Any deviations in pose or camera angle had to be imperceptible, which really pushed the AI’s accuracy to its limits.
This experience taught me a lot about how to write effective AI prompts for text to image generation, especially when aiming for such detailed pose replication. Adjusting prompts to emphasize strict constraints and alignment priorities is key to avoiding common mistakes like identity shifts or compositional errors.
For creators wanting to replicate complex actions or poses without losing character identity, this approach is a game changer. It opens doors to creating consistent character animations, storyboards, or visual effects with AI’s help.
