SUMMARY:

Almost every AR investigation and reconstruction requires us to make photographs for documentation, analysis (including photogrammetry), demonstration, and to use as exhibits in reports, depositions, and trials. Three tools—tripods, polarizers, and flash—help ensure you create consistent, accurate, good quality, and useful photographs.

-1- Tripods:     Features to look for.

                        How tall should they be?

                        Uses:    steady camera

                                    level camera

                                    low light or long exposures

                                    when you need to be in the photo

                                    before and after photos

                                    multiple photos from same position

                                    focus stacking.

                        Choosing a tripod head.

 -2- Polarizers:  Reduce glare and enrich saturation.

                        Only filter whose effects you can’t replicate in Photoshop.

                        Useful for almost all site and vehicle inspections.

                        Especially critical for documenting tire marks.

                        Can bring out details on vehicles you can’t see with the naked eye.

 -3- Flash:         Using ambient, full flash, or fill flash.

                        Add light where it’s needed.

                        Show textures.

                        Reduce excessive contrast.

                        Freeze motion.

                        Multiple flashes bring out details in shadows.
