Conclusion
The results show that the generative AI model performed well in understanding the scene and camera position, but struggled with the aesthetic aspect. Here’s a breakdown:
- Camera Position: The model scored 0.39, 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 in the prompt.
- Shot Analysis: The model scored 0.57, which falls within the “good” range. This indicates that the model was able to understand the scene described in the prompt reasonably well.
- Aesthetic Analysis: The model scored 0.10, which is within the “very good” range of -0.2 to 0.1. This means the generated image’s aesthetic closely matched the expected aesthetic described in the prompt.
Overall, the model demonstrated a good understanding of the scene and a very good ability to match the desired aesthetic. However, it struggled to accurately capture the intended camera position.
