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 0.2, which is considered below average. This indicates that the generated image’s camera position deviated significantly from the prompt’s instructions.
• Shot Analysis: The model scored 0.58, which is considered good. This means the generated image’s shot composition was fairly close to what was expected based on the prompt.
• Aesthetic Analysis: The model scored 0.06, which is considered average. This suggests that the generated image’s aesthetic was somewhat different from what was expected, but not drastically so.

Overall, the model seems to be better at understanding the scene and shot composition than it is at accurately capturing the desired camera position and aesthetic.
