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 0.25, which is below the “good” range of 0.5 to 0.75. This suggests the model didn’t accurately capture the intended camera position in the prompt.
• Shot Analysis: The model scored 0.62, falling within the “good” range. This indicates the model was able to understand the scene described in the prompt reasonably well.
• Aesthetic Analysis: The model scored 0.12, which is slightly above the “very good” range of -0.2 to 0.1. This suggests the generated image’s aesthetic deviated somewhat from the expected aesthetic described in the prompt.

Overall, the model demonstrated a good understanding of the scene and shot composition, but struggled to accurately capture the intended camera position and aesthetic.
