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 0.16, 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 in the prompt.
• Shot Analysis: The model scored 0.49, 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 0.12, which is within the “very good” range of -0.2 to 0.1. This means the generated image’s aesthetic closely matched the expected aesthetic described in the prompt.

Overall: While the model excelled in capturing the desired aesthetic, it struggled with accurately representing the camera position and scene described in the prompt.
