SUMMARY

The discussion revolves around the challenge of identifying an existing duct in a photograph of a recently renovated building. Participants analyze the optical illusion created by the duct's reflection and surrounding objects, which obscures its visibility. The duct, measuring 12 inches high, is located above and to the left of an HVAC unit, with much of it hidden behind pipes and other structures. The conversation highlights how the addition of red outline sketches inadvertently made the duct less visible, demonstrating the complexities of visual perception in architectural contexts.

PREREQUISITES
  • Understanding of HVAC systems and ductwork design
  • Familiarity with optical illusions and visual perception
  • Basic knowledge of architectural photography techniques
  • Experience with drafting tools and sketching in architectural contexts
NEXT STEPS
  • Research techniques for improving visibility in architectural photographs
  • Explore the principles of optical illusions in design
  • Learn about HVAC duct design and installation best practices
  • Study the impact of lighting and contrast in visual presentations
USEFUL FOR

Architects, HVAC engineers, visual designers, and anyone involved in building renovations or architectural photography will benefit from this discussion.

HEYYYYYYYYY! Somebody was fiddling with brightness and contrast settings!
Did you read my posts...? :rolleyes:

I lowered the contrast to simulate the draft-quality printout I used when I sketched it for my boss. Yes, that enhances the illusion.

No he didn't. The q was always there, it was hidden behind invisible-text-coloured construction lines. He's removed them for clarity.

I'd outline just the parts you can see, but then people would yell at me...

For those who don't even know where to begin looking in the image that shows the duct, this might help.
