Conclusion
The results show that the generative AI model performed well in understanding the camera position and shot composition, but struggled with the aesthetic expectations. Here’s a breakdown:
- Camera Position: The model scored 0.25, which is below the “good” range of 0.5 to 0.75. This suggests that the model didn’t fully capture the intended camera position described in the prompt.
- Shot Analysis: The model scored 0.65, which falls within the “good” range. This indicates that the model was able to understand and translate the scene description in the prompt into a visually coherent shot.
- Aesthetic Analysis: The model scored 0.14, which is outside the “very good” range of -0.2 to 0.1. This suggests that the generated image didn’t quite match the expected aesthetic style described in the prompt.
Overall, the model demonstrated a good understanding of shot composition but needs improvement in capturing the intended camera position and aesthetic style.
