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 considered below average. This suggests that the model didn’t accurately capture the intended camera position described in the prompt.
• Shot Analysis: The model scored 0.615, which is considered good. This indicates 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 0.09, which is considered very good. This means that the generated image’s aesthetic was very close to the expected aesthetic described in the prompt.

Overall, the model seems to be better at understanding the scene and creating a shot that matches the prompt, but it needs improvement in accurately capturing the intended camera position. The model’s ability to create an image with the desired aesthetic is a strong point.
