The Paradox of Stage Lighting in Canada: Sometimes So Transparent that It’s Invisible
Bibliographic record
Abstract
As theatre historians tell us, our word “theatre” is rooted in performance as a visual experience, deriving from the Greek “theatron,” literally “a place where you see or behold.” And that emphasis is continued in our only English word for a single member of an audience: “spectator.” Since most of our theatre is performed in the dark (either indoors or outdoors after nightfall), most of it would be invisible without stage lighting, and yet stage lighting in Canada suffers from a strange kind of disregard. The Canadian Opera Company’s (COC) 2001-2002 subscription brochure provides a case in point. The opening paragraphs, by General Director Richard Bradshaw, emphasize the increasingly visual importance of contemporary opera: “Increasingly, opera is exploring our heightened sense of visual acuity. What I’m interested in … is work that engages you to the point where you see with your ears and hear with your eyes” (2). As if to emphasize his point, almost every page of the brochure is dominated by the image (or partial image) of a face sculpted by dramatic key lighting. Paradoxically, however, as the brochure lists its seven impressive-sounding productions for 2001-2002, it follows a very Canadian (and perhaps international) pattern of listing the composer, conductor, stage director, set and costume designers and then the major singers. There is, of course, no mention of lighting designers; their work is visible everywhere in this brochure, but they remain unnamed and in the wings (or on the grid).

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
