What we'll work through
- Weeks 1-3: Beyond 1:1 magnification
- Reversing lenses, bellows systems, calculating effective aperture, dealing with diffraction limits, focus rail precision requirements, vibration isolation methods.
- Weeks 4-6: Specialized lighting
- Fiber optic positioning, polarized light setups, dark field and bright field techniques, controlling specular highlights on metallic surfaces, UV and infrared applications.
- Weeks 7-9: Focus stacking mastery
- Automated rail programming, calculating step distances, Zerene versus Helicon versus Photoshop, handling misalignment, retouching stacking artifacts, optimizing for different subject types.
- Weeks 10-12: Production workflow
- Calibration for measurement, maintaining color accuracy, building repeatable setups, batch processing hundreds of frames, archiving raw stacks versus final images.
Prerequisites: You should be comfortable with manual focus, basic focus stacking, and understand depth of field calculations.
This isn't about taking prettier flower photos. We're talking magnifications above 2:1, where your depth of field measures in millimeters and any vibration ruins the shot. You'll need patience and a methodical approach.
Technical problems at high magnification
Diffraction becomes your enemy past f/16. We'll calculate optimal apertures for your sensor size and work through focus stacking with 50+ frames. You'll learn to build rail systems for precise movement and understand why even electronic shutters cause problems at this scale.
Lighting gets complicated when your subject is 5mm across. We'll experiment with fiber optic illuminators, cross-polarization to eliminate reflections, and dark field techniques borrowed from microscopy. Half the course involves building custom solutions because commercial gear doesn't always work at these magnifications.
Real applications
Students have used these techniques for jewelry documentation, forensic work, and scientific imaging. We'll cover calibration for accurate measurements and maintaining consistency across image sets.
