SAFETY AND ACCIDENT RECONSTRUCTION
−− Exposure: aperture, shutter speed, ISO, histograms, reciprocity, noise −− Focus: manual vs. autofocus, DOF, where to focus −− Perspective −− Live view: when and how to use −− Composition: distractions, dead space, level, reference elements, parallax −− Light and shadow −− Lens choices: zoom, prime, fixed, macro, angle of view DAY TWO • Flash Fundamentals −− Exposing for flash −− TTL vs. manual - when to use which −− On vs. off-camera flash −− Multiple flashes −− Flash accessories, modifiers, reflectors −− Macro • Equipment That Works −− Polarizer −− Camera support: tripod, monopod, ground pod, bean bag, windshield mount −− Ladder, pole, or drone for high viewpoint; tethering −− Camera cases, bags, belt systems, strap −− Remote release −− Batteries: camera, flash, accessories −− Flashlight: head lamp, focus assist, equipment at night −− Camera, lens, and equipment cleaning • Close-up and Macro Photography (1 hour) −− Specialized equipment: macro lens, ring flash, macro tripod or ground pod, close-up lenses, macro focusing rail −− Focusing −− Micro photography • Photographing Outdoors −− Overall establishing shots −− Closer detail shots −− TPE to locate sun angles −− Sequences to show sight distance −− Sequences to show vehicle or pedestrian movements −− Equipment: polarizer and monopod −− Vehicles: 360° coverage, multiple angles and elevations, polarizer plus fill flash −− Components and broken pieces: Temporarily label potentially ambiguous subjects (LR, A2RI, etc.). Don’t deface. −− Weather: wet reflections, glare, fog limiting sight distance, wet streaks across vehicle evidence, snow, hail, etc. −− Night photography: ambient (visibility), flash, flood, or painting with light, ambient and headlight blooming, documenting conditions as seen, tethering DAY THREE • Photographing Indoors −− Ambient light, continuous supplemental, flash −− Supplemental light: flash, LED, work lights, light modifiers,
light stands, effects of windows and doors −− Balancing ambient and fill • Photographing Testing) −− Documenting equipment, facility, and test subjects (before and after tests) −− Including scales −− Vehicle and component testing: document vehicle, test equipment, dynamic tests −− Rollover and truck braking examples −− Chem lab testing: sample area before, sample being removed, sample area after, sample itself, labeling −− Mechanical lab testing: test subject before and after, including pieces, if applicable • Post-Processing Workflow −− Develop a consistent methodology: varying workflow is less defensible −− Calibrate monitor: for color, for night photography −− Download images −− Sort: delete test shots, out-of-focus, bad exposure, duplicates, group and organize similar subjects −− Rename photos: CO_file number_sequential number; add descriptor if helpful (LF, A2RO, etc., if not labeled in photo) −− Back up files −− Image resolution: screen vs. printing −− Optimizing Images: camera calibration, noise reduction, sharpening for screen or print, lens correction, exposure, shadows, highlights, clarity, vibrance −− Resizing and saving images - NOT PDFs! −− Distributing images: online file sharing sites, physical storage −− Printing for deposition or trial exhibits • Reading and Interpreting EXIF Data • Video −− Equipment: camera type, video head, vehicle mounts −− Camera stationary or camera moving • Special Topics −− Panoramas: tripod-mounted, handheld, drone, taking overlapping images, stitching in post −− Photographing travel routes from vehicle −− Photographing sight distance traffic patterns −− Photographing for photogrammetry −− Adjusting photos from other sources and extracting detail from night photos −− Pattern matching: tire track over body −− Creating photo exhibits: merging photos, adding visibility obstruction to accident site photo, demonstrating effect of long lens compression −− Camera and focal length −− Date original photo made
