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 0.2, indicating it’s not very good at reacting to camera positions in the prompt. This means the generated image’s camera position significantly deviates from what was requested.
• Shot Analysis: The model scored 0.47, which is good. This means the generated image’s shot composition is fairly close to what was described in the prompt.
• Aesthetic Analysis: The model scored 0.14, which is very good. This means the generated image’s aesthetic is very close to what was expected.

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