@PerleLabs Middle

Architectural Inconsistencies: The tower’s stonework and window details appear unnaturally uniform and lack the subtle wear and variation present in real photographs of the historic structure.

It's the final week of Human CAPTCHA: Round 7

You made it this far… but we’re not going easy on you. One of these is a real photograph of a hot air balloon, the rest is AI-generated. Can you tell which one it is?

Respond with Left, Middle, or Right and tell us why below!

Submissions close Sat, Feb 28 at 11:59pm UTC. Answers revealed Sunday.

@PerleLabs Left

Consistent perspective and scale: The two smaller hot air balloons in the background of the left image appear at a natural distance and scale relative to the main balloon, which is consistent with real-world photography.

@PerleLabs Right

I think the right picture is real, and the left one is AI-generated.

The right image depicts Positano on the Amalfi Coast in Italy, a well-known and real tourist destination. The colorful houses on the cliff, the beach, and the boats are consistent with real photos.

@PerleLabs Right

I think the right image is the real photograph, and the left one is AI-generated.

The tiger on the right is on a typical forest path, with natural vegetation, lighting, and ground details that fit a wild tiger's habitat.

Perle Human CAPTCHA #4

It's time to put your human judgement to the test again. One of these images of a tiger is a real photograph, one was generated by AI.

@PerleLabs Right

- The image on the right (orange): This is a real photograph.
- The texture, sheen, and subtle imperfections on the orange's skin are entirely natural, consistent with a real fruit.
