FilmDiag: Camera & Development Diagnostic Kit + Service
A mailed diagnostic kit containing standardized test film, exposure reference cards, and a detailed photographic guide that photographers shoot through their camera under controlled conditions, then mail back with their defective roll. A trained technician analyzes both rolls side-by-side under a light table, produces a written diagnostic report pinpointing the exact failure mode (shutter timing, light seal degradation, sprocket misalignment, development temperature variance, etc.), and recommends specific fixes or repair vendors.

Value Proposition
Eliminates guesswork by providing forensic-level diagnosis from a human expert who can see the exact pattern, timing, and severity of defects. Photographers know whether to repair their camera, change their loading technique, or switch labs—saving hundreds in wasted film and repair costs. Faster and more reliable than forum advice; cheaper than sending camera to repair shop blind.
Target Audience
Serious amateur and semi-professional film photographers aged 25-55 who own multiple cameras and shoot 10+ rolls/month; those who've had 2+ ruined rolls in past year
Key Features
- Reusable diagnostic test film cartridge with pre-marked exposure zones
- Printed exposure reference card showing correct vs. defective patterns for 12 common failure modes
- High-res light table analysis with macro photography documentation
- And more, with full implementation detail...

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.
