Conclusion

The results of the analysis show that the generative AI model performed well in terms of 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 indicates that the model didn’t accurately capture the intended camera position described in the prompt.
• Shot Analysis: The model scored 0.47, which is also below the “good” range. This suggests that the model didn’t fully understand the scene described in the prompt and didn’t create an image that accurately reflects it.
• Aesthetic Analysis: The model scored 0.11, which is within the “very good” range of -0.2 to 0.1. This means that the generated image’s aesthetic closely matched the expected aesthetic described in the prompt.

Overall, the model seems to be better at understanding the desired aesthetic than the scene and camera position. This suggests that the model might need further training to improve its ability to accurately interpret and translate prompts into images.
