In August of 2007, in response to numerous requests, we formed Clearly Visible Presentations, LLC.  Our mission is to teach the science and technology of optics, lighting, visibility and digital photography to the forensic investigation community.

We do not provide direct consultation on forensic cases.  But, our staff has over 40 years' experience in the courtroom environment.  We understand the tasks assigned to forensic investigators and provide training to ensure that evidence is collected and analyzed using scientifically valid techniques.

You didn't see the pedestrian?                             
At 25 miles per hour and with a sight distance of 630 feet, you had more than 17 seconds to see the pedestrian walking in the street and avoid striking him.  Yet, you say you didn't see him?  Perhaps you weren't looking...
This fatal collision occurred in December of 2013 at 11:25 p.m.  The pedestrian had stepped into the street because the sprinkler system had turned on and was spraying the sidewalk.  The driver, who was heading home from a long day at work did not know that there was a pedestrian until he felt the thump of the car striking and killing him.  He had driven over 600 feet at about 25 miles per hour and never did see the pedestrian.

The defense in this case made various claims as to why the pedestrian could not be seen.  They said, "It was well after dark." and "Headlights don't penetrate that far." and "The plaintiff was wearing dark clothing."  But, while all of those things were true, none of it mattered in this case.  It only took one site visit to learn why.

While it was "well after dark", the site was anything but dark.  Street lights were on all along along the main boulevard.  Light spilled through the spaces between trees onto the access drive. The pedestrian was silhouetted against several stripes of street lighting that spilled through the spaces between trees 

The driver confirmed that he was driving on low beam and it was true that on that SUV, low beams did not produce 0.3 foot-candles beyond about 230 feet.

The pedestrian was, in fact, wearing black clothing.  But, that only improved the silhouette contrast.

Under the circumstances, it would have been difficult to hide this pedestrian from anyone that was paying a modicum of attention.

There were no police scene photographs taken.  It was not until investigators went to the site at night that it became obvious that there was more than sufficient light to see that someone was walking in the street and headlighting didn't matter.  This driver was grossly inattentive.
Go to the site!  There is something there that will bite you when/where you least expect it.
