Bad Crime Scene Photos
Modern digital photography has solved many of the technical challenges forensic photographers encounter. However, even with the advantage of instant feedback, issues of how to properly expose crime scene photographs still exist. Images are being captured and not corrected, rendering them unusable, which begs the question, “why?”. Effective crime scene photography is a significant element of solving a criminal event. Therefore, it is vital to understand the issues that many hinder a forensic investigator when capturing these images. The factors within the scope of the study presented here, are as follows: the overall attitude of the forensic investigator that can impact the quality of photographs; the lack of quality training in the specific requirements of forensic photography can result in incomplete or unusable images; professional, well-maintained equipment will capture better-quality images (a lack of good tools making it more difficult for the investigator to do their job well); and the harsh sights and smells of the crime scene environment that can be difficult for even the most experienced investigator. This presentation will summarize the feedback from over 175 forensic photographers worldwide to examine why images are being captured and not corrected.

Authentication Admissibility
Digital images are the predominant visual medium used by counsel to advance trial narratives in the courtroom. Counsel therefore rely upon forensic experts to provide the imagery for use at trial. Depending upon the case, imagery may include ground-based or aerial still images and video, TLS 3D visualizations, satellite imagery, and immersive visual environments. Being able to accurately visualize scenes, objects, and people can be of significant value in understanding complex locations and events, and in reaching conclusions on identification. As the ultimate aim of a trial is to ascertain the truth, digital imagery can aid in that worthwhile endeavor. Learn about the legal perspective regarding digital images as the presenter discusses admissibility, authentication, and effective courtroom presentations.

Forensic Photography in Disaster Victim Identification
Photography is an integral part of any DVI operation, as developed and internationally agreed upon by the Interpol DVI Standing Committee. Its use is described in the Interpol DVI guidelines and should be applied in all DVI operations particularly in the search and rescue phase as well as in the post-mortem examination in the way described in the Interpol DVI protocols.

Luminance (INCR), Nighttime Photography
Mapping the luminance values of a visual scene is of broad interest to accident reconstructionists, human factors professionals, and lighting experts. Such mappings are useful for a variety of purposes, including determining the effectiveness and appropriateness of lighting installations, and performing visibility analyses for accident case studies. One of the most common methods for mapping luminance is to use a spot type luminance meter. This requires individual measurements of all objects of interest and can be extremely time consuming. Nitere, a commercially available software, allows the user to calibrate their camera and estimate luminance from the resultant still images and video. The process of capturing appropriate images and video for luminance estimation will be discussed. The science behind estimating luminance from a CCD sensor will be explained. And the process of using Nitere will be taught.

Cross-Polarization Photography
Photographic documentation of human tissues affected by various forms of pathology and trauma can present unique challenges for the forensic investigator. Sweat and condensation, blood and other bodily fluids, injuries hidden by burns or inorganic matter, can all cause issues of reflective artifacts or competing tone and texture. Additionally the documentation of tattoos, scars, and body markings in thermally damaged or darkly pigmented skin can be difficult for identification purposes.
While modern camera systems and techniques are able to mitigate some of these problems through exposure control and lighting solutions, the use of cross-polarization has greatly enhanced the ability of appropriately equipped and trained forensic investigators to document these findings. A lens mounted circular polarizer typically used to minimize environmental reflections caused by atmospheric lighting, combined with a controlled, polarized light source can bring a level of control that will allow for documentation of highly reflective surfaces, such as human tissue, while increasing contrast and saturation.
In this presentation I plan to provide an explanation of the science behind lighting human tissue using cross-polarization, how to source and deploy the equipment and techniques, and show several examples of the process. Wet tissues (Heart, Kidney, Lungs), tattoos on dark/thermally damaged skin, enhanced visualization of bruising on skin, visualization of bruising on muscle.

Why Shoot Raw?
Forensic images can be crucial pieces of evidence. Photos need to be true, fair and accurate representations of the scene they depict. Does your camera and it's settings fulfill that obligation? Can you explain how your camera processes a digital image?

Having overhead photographs of vehicles at their impact positions is an extremely vital role in documentation and presentation of collision dynamics. Drones have recently been deployed to gather this data, but what happens when you can't fly due to proximity to a hazard? This presentation explores a cost effective alternative to gather the powerful photos that will excel your case work.

Documenting Bullet Trajectories
In July 2012, a lone gunman shot numerous rounds from multiple firearms into a crowded movie theater in Aurora, Colorado. As part of the scene documentation and shooting reconstruction process, it is necessary to determine and record approximate bullet trajectories. This presentation is a discussion of the equipment, photographic techniques, and challenges of photographing multiple lasers in a large indoor venue.

Infrared & UV Photography
Infrared (IR) and ultraviolet (UV) photography have been part of biomedical and forensic photography for many years. Information may be revealed using invisible radiation. Historically, IR and UV sensitive silver halide emulsions were used. Today converted digital cameras create images faster with more consistent and superior results compared with analog methods. These imaging techniques have been used for identifying trace evidence, enhancing fingerprints, revealing details of obliterated tattoos, documenting bite marks/bruising as well as counterfeit materials. Digital technologies have made infrared imaging even easier for surveillance techniques. Digital cameras, however come with pitfalls concerning the interpretation of the images. Issues of tonal representation and exposure cannot be equated to visible light imaging. In addition, some filters commonly used for film photography give totally erroneous results with digital technologies. This presentation highlights some difficulties encountered with digital technologies and discusses the conversion of traditional digital cameras for use with IR and UV techniques making them a useful scientific and forensic imaging tool. The presentation aims to demystify some of the processes involved in IR/UV digital photography, broaden the knowledge of participants in applications and identify the specific dangers in the interpretation of the IR/UV images.

Cross-Polarization Photography
Photographic documentation of human tissues affected by various forms of pathology and trauma can present unique challenges for the forensic investigator. Sweat and condensation, blood and other bodily fluids, injuries hidden by burns or inorganic matter, can all cause issues of reflective artifacts or competing tone and texture. Additionally the documentation of tattoos, scars, and body markings in thermally damaged or darkly pigmented skin can be difficult for identification purposes.
While modern camera systems and techniques are able to mitigate some of these problems through exposure control and lighting solutions, the use of cross-polarization has greatly enhanced the ability of appropriately equipped and trained forensic investigators to document these findings. A lens mounted circular polarizer typically used to minimize environmental reflections caused by atmospheric lighting, combined with a controlled, polarized light source can bring a level of control that will allow for documentation of highly reflective surfaces, such as human tissue, while increasing contrast and saturation.
In this presentation I plan to provide an explanation of the science behind lighting human tissue using cross-polarization, how to source and deploy the equipment and techniques, and show several examples of the process. Wet tissues (Heart, Kidney, Lungs), tattoos on dark/thermally damaged skin, enhanced visualization of bruising on skin, visualization of bruising on muscle.

Scientific Purpose of Forensic Photography
Since the advent of digital photography, the scientific purpose of Forensic photography has been greatly distorted by the excessive use of automatic settings of the technical means and we forgot that photography, to ensure a more accurate and objective representation of what is intended to be exposed, uses science: optics, mechanics, mathematics and extrasensory perception. Taking into consideration the natural evolution of science and technology, we consider that a new analysis is required, to identify if the methods and techniques we use for Crime Scene photography are still serving the scientific purpose of obtaining an objective representation of the crime scene and to record, in an objective way the main objects or to establish the dimensions or distances between various objects, located in the criminal field.

Perspective correction
In some situations, it is difficult or impossible to take perpendicular photos of evidence such as latent friction ridge impressions or bloodstain patterns deposited on flat surfaces like doors, windows, walls, floors or ceilings. A simple perspective transformation function can be used in combination with right angle scales to transform such non-perpendicular photo images to a perpendicular perspective. The theory will be described briefly followed by example exercises. The perspective transformation function has been implemented within a software application that will be used in the exercises to show how to quickly correct non-perpendicular images. The accuracy of the transformation will also be discussed.

UV & IR Digital Photography Equipment Considerations
Getting started with multispectral imaging presents many challenges. You may find yourself wondering which camera, lens, and filter combinations work best while finding that there isn’t much information available online. When it comes to taking UV & IR images, your equipment can either save you hours of work or really slow down your overall workflow. The goal at Kolari Vision is to educate professionals on how to put together a multispectral imaging set up that will complement their workflow while simplifying the approach to capturing ultraviolet and IR images. Many professionals find that when opting in for commercial forensics photography packages, they may lack the capabilities and equipment required to be able to take UV, visible light, and IR images with one camera. The alternate approach is to use consumer cameras and 3rd party equipment and build your own multispectral imaging kit, which requires some specialized knowledge. Here we present some equipment considerations around camera, lens, filters, and light sources to ensure accurate capture of the target wavelengths. We will review using general purpose lenses for UV and IR photography while going over the limitations that need to be considered to successfully capture UV and IR. We will go over how to do this type of photography on a budget, as well as present a ready-to-go kit built from the ground up for this type of shooting.

Scientific Purpose of Forensic Photography
Since the advent of digital photography, the scientific purpose of Forensic photography has been greatly distorted by the excessive use of automatic settings of the technical means and we forgot that photography, to ensure a more accurate and objective representation of what is intended to be exposed, uses science: optics, mechanics, mathematics and extrasensory perception. Taking into consideration the natural evolution of science and technology, we consider that a new analysis is required, to identify if the methods and techniques we use for Crime Scene photography are still serving the scientific purpose of obtaining an objective representation of the crime scene and to record, in an objective way the main objects or to establish the dimensions or distances between various objects, located in the criminal field.

Perspective correction
In some situations, it is difficult or impossible to take perpendicular photos of evidence such as latent friction ridge impressions or bloodstain patterns deposited on flat surfaces like doors, windows, walls, floors or ceilings. A simple perspective transformation function can be used in combination with right angle scales to transform such non-perpendicular photo images to a perpendicular perspective. The theory will be described briefly followed by example exercises. The perspective transformation function has been implemented within a software application that will be used in the exercises to show how to quickly correct non-perpendicular images. The accuracy of the transformation will also be discussed.
