This three–day course builds on skills learned in the Basic course, teaching more advanced image capture techniques, advanced camera equipment handling techniques, and advanced image enhancement in image processing the s to be able to get more out of crime scene images. Typically, more that 50% of the class time is spent doing hands on camera and computer exercises, with close individual attention from the instructors.
Topics covered in this course include:
- Problems in close-up and macro photography- fingerprints on a variety of surfaces, tool marks, ballistic evidence.
- Flash Photography- Automatic vs manual settings in flash photography and why/when to use either; determining the guide number (indoor and outdoor) for any flash or light source; bounce vs. direct flash, fill-flash and closeup flash photography.
- Telephoto/surveillance photography– issues, problems, solutions; using long focal length lenses to best advantage.
- Stopping Motion- How to get sharp photographs of moving objects, how to use camera settings to demonstrate motion, with and without electronic flash.
- Cross polarization and diffusion: the simple techniques for photographing fingerprints and other evidence on shiny or highly polished surfaces.
- Photo Workflow- handling and processing images according to the IAI/FBI Scientific Working group on Imaging technology guidelines. Shortcuts to better photography and image management in the lab.
- Processing raw images: Finding and opening an image; basic enhancement techniques; brightness, contrast, shadow, and highlight modification; scaling fingerprint and tool mark images; using sharpening and contrast to retrieve lost image detail
- High Dynamic Range Photography- extending visibility further into shadows and highlights
- Background reduction in fingerprint and other highly detailed evidentiary images; color isolation, FFT (Fast Fourier Transform) and other photographic and software techniques. Includes separating overlapping fingerprints.
- History of digital imaging key cases and what they mean- Frye and Daubert cases on digital imaging. Digital Imaging Acceptance.
Students should bring a laptop computer along with any image enhancement software they currently use; open source software will be available if needed.
The Basic Photography course is a pre-requisite, unless exempted by the instructors.
