Week 7 Bench: Measuring a reflection

Recovering readable text from a photograph of light bounced off something that was never meant to be a display

5 April 2027

Before the Bench

No equipment to bring — the supplied photograph set does the capturing for you this week, so the session is about the reconstruction, not the shot.

In the Bench

Working from a set of photographs of a monitor reflected in glasses, a teapot, and a plain wall, attempt to recover the displayed text from each, starting with the easiest surface. Note where recovery becomes a matter of computational sharpening and where it becomes physically impossible no matter how much processing is applied — a curved reflective surface and a diffuse matte one fail for different reasons, and the difference matters more than the failure itself.

Afterwards

Keep your notes on which surface failed and why. This channel is the hardest of the seven to score on week 10’s rubric — the equipment is a camera and the defence is a floor plan — and an argument you can already make about why “hard to exploit” and “hard to defend” come apart here is worth more there than a number you cannot justify.

The spec

What you bring to the session. Written so a reader can tell whether it has been met without asking you.
