Opportunity BasketDOF Reference Card + Laminated Field Guide System
A professionally designed, laminated wallet-sized card (3x5 inches) with pre-calculated DOF tables organized by common camera sensor sizes, focal lengths, and apertures. Includes a companion laminated reference poster (11x14) for studio/home use with visual depth-of-field diagrams. Cards are printed on weather-resistant material with UV-protective coating and sold as bundles (individual cards + poster + digital PDF backup).

Value Proposition
Eliminates mental math and formula memorization entirely—just look up your lens/aperture combo and read the exact DOF. No phone battery drain, no app loading time, works in harsh sunlight where screens are unreadable. Customizable per camera body (Canon, Nikon, Sony, etc.) so only relevant data appears. Cheaper and faster than pulling out a phone or calculator mid-shoot.
Target Audience
Professional photographers, wedding/event shooters, photography students, working cinematographers who shoot in variable field conditions
Key Features
- Pre-printed DOF values for focal lengths 14mm–400mm in 1mm increments
- Organized by aperture (f/1.4 through f/22) and common sensor sizes (Full Frame, APS-C, Micro Four Thirds)
- Hyperfocal distance tables for landscape/infinity focus
- And more, with full implementation detail...

Photographers struggle to calculate depth of field accurately without memorizing complex mathematical formulasProfessional and amateur photographers frequently need to calculate depth of field to achieve proper focus in their shots, but the full DOF formula is complex and difficult to remember in the field. They resort to simplified approximations that sacrifice accuracy, leading to missed shots or wasted time recalculating. Current solutions either require carrying reference materials, using unreliable mental math, or relying on camera features that don't always account for their specific lens and shooting conditions.
