Conclusion

The results of the analysis 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 0.3, which is below the “good” range of 0.5 to 0.75. This indicates that the model didn’t fully capture the intended camera position described in the prompt.
• Shot Analysis: The model scored 0.59, which falls within the “good” range. This suggests that the model was able to understand the scene and create a shot that was relatively close to what was described in the prompt.
• Aesthetic Analysis: The model scored 0.23, which is significantly lower than the “very good” range of -0.2 to 0.1. This indicates that the generated image’s aesthetic deviated significantly from the expected aesthetic described in the prompt.

Overall, the model demonstrated a good understanding of the scene and shot composition, but struggled to achieve the desired aesthetic.
