@PerleLabs Middle The middle one shines too perfectly, like it just rolled off a digital assembly line, while the left and right actually breathe light catching edges, reflections that feel lived in, backgrounds that don't lie.

Alright… this is it. Final Human CAPTCHA challenge 👉👉 We saved the best for last. There are 3 images. Only ONE is AI-generated. Your job is to tell us if it's the one on the Left, Middle, or Right. Submit your guesses by Sat, Feb 28 at 11:59pm UTC. As usual we'll be revealing the answers on Sunday! If you got 3+ right, we’ll share how to claim your reward next week.

@PerleLabs Left The sky on the left has a soft sunrise look — it's warmer (more orange/pink) close to the ground and gets cooler (bluer) higher up. There's also a gentle haze that makes far-away balloons look smaller and a bit fuzzy. That's how real photos look in the morning.

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 Right. The scene has natural imperfections. Slightly uneven road texture, realistic reflections on the car, and building details that match with distance.

Perle Human CAPTCHA #6 🏎️ One of these sports car photos is real. The other was generated by AI. Comment “left” or “right” with your guess, and tell us why 👀 Submissions close Sat, Feb 21 at 11:59pm UTC. Answers revealed Sunday.

@PerleLabs right with consistent shadows, buildings following the mountain contour, and varied window and balcony details make the right image look authentically real and photographic.

Perle Human CAPTCHA #5 📸 Let’s keep your captcha streaks alive. One of these vacation photos is real, and one was generated by AI. Which one is real? Reply "left" or "right" and explain why ↓ This week's submissions close Sat, Feb 21th at 11:59pm UTC. Both answers will be revealed on Sunday.

@PerleLabs left The pose and details feel natural: weight on the front paws over the log, slightly messy fur with asymmetrical stripes, soft shadows from overcast lighting—classic zoo snapshot vibe.

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. Which one is real? Reply "left" or "right" and tell us why ↓ This week's submissions close Sat, Feb 14th at 11:59pm UTC. Both answers will be revealed on Sunday 👀

@PerleLabs Left The apple shot has really natural camera cues: a believable specular highlight, tiny surface imperfections, realistic bokeh in the background, and a convincing contact shadow/reflection on the wood.

Perle Human CAPTCHA #3 📷 One of these images of fruit is a real photograph, one was generated by AI. Which one is real? Reply "left" or "right" and why 👇 You have until Sat, Feb 14th at 11:59pm UTC. This week's answers will be revealed on Sunday.

@PerleLabs AI Because the scene appears overly pristine and perfectly arranged — the lighting is uniformly balanced and the textures look painterly but lack natural brush imperfections.

Perle Human CAPTCHA Round 2 ✌️ Was this landscape art created by a real artist, or AI generated? Reply with "Human" or "AI" and tell us why! Deadline is Sat, Feb 7th at 11:59pm UTC. This week's answers will be revealed on Sunday. PS: Use your own judgement and trust your instincts!

@PerleLabs H This photo looks real because the lighting and shadows are natural and imperfect. The details and readable text on the signs are consistent, which AI often gets wrong.

Perle Human CAPTCHA Round 1 Was this photo taken by a real person or generated by AI? 📸 Reply with a letter and tell us why: H = Human A = AI Deadline to submit is Sun, Feb 7th at 11:59pm UTC. It's go time 👇
