CinemaLogic: Interactive Defect Diagnosis Tool + Peer Verification Network
A web app where photographers upload high-res scans of their defective negatives alongside metadata (camera model, film stock, development lab, loading method) and answer a guided diagnostic questionnaire (20 questions on shooting conditions, camera history, loading technique). The app analyzes the defect pattern (dark band location, density, edge sharpness) against a database of 500+ reference images and generates a ranked list of probable causes with confidence scores. Users can then submit their diagnosis to a peer-review network of experienced film photographers and technicians who validate or refine it—earning reputation points for accurate diagnoses.
25 weeks • 70% confidence
Value Proposition
Instant preliminary diagnosis (within hours, not days) at $0-15 vs. $65+ for physical diagnostic service. Crowdsourced validation from experienced photographers builds confidence in diagnosis. Photographers learn WHY defects occur, not just what to do. Repair technicians get diagnostic leads and case studies. Network effects: more users = better reference database = more accurate diagnoses.
Target Audience
Film photographers aged 20-50 who are engaged in online communities; those who want fast, low-cost diagnosis and enjoy collaborative problem-solving; also appeals to camera repair technicians and film educators seeking diagnostic cases

Film photographers unable to diagnose and fix dark band exposure defects in developed photosFilm photographers spend time and money developing film only to discover dark bands or light leaks ruining entire rolls, with no clear way to identify the root cause (camera malfunction, loading error, or development issue) or prevent it next time. Current solutions require expensive camera repairs, trial-and-error testing, or consulting forums with inconsistent advice, leaving photographers frustrated and out of pocket for wasted film and development costs.
