"I take photos all the time, mostly for work, but also for fun. I took a photography class many, many years ago with an all-manual K1000, and even owned a light meter once. But when digital came along, I pretty much forgot everything about f-stops, apertures, filters, and lighting and have relied on the software to get it right. Or right enough. Optics, Lighting, and Visibility for the Forensic Investigator's emphasis on the fundamentals of how human eyes and cameras interact with light, and how light interacts with everything it touches, coupled with the practical exercises with our own digital cameras has improved my understanding of what is important in nighttime events, and improved my chances of getting that important night-shot at a scene. I have regained some of the camera skills I once had and found new ones, and learned to apply them to my current digital camera. There were numerous tips and tricks regarding vision and photography that I wish I’d known before, but I’m glad I know now, as I’m sure I will use them. I unreservedly recommend this course to anyone who takes photographs or has to talk about “what someone could see” in daytime or at night."

I did find this class to be one of the best I have been to. I am a much better learner when it comes to "hands-on" training, so it was helpful to have the background in the classroom, the outside exercises to demonstrate it, and the problems to work through and drive it home. I actually find this stuff to be pretty interesting, and have been talking with others about it, trying to explain some of the things I learned! I rode my motorcycle last night, for two hours, on the way to the Cape Cod. I was studying the patterns of luminance, illuminance, reflectivity, etc. I was laughting most of the way!

"I have known Mr. Sobek professionally for over fifteen years. I have worked with him on accident reconstruction cases, and I have seen him teach. He has an obvious love for his subject. This, coupled with his extensive experience in the field, makes him an outstanding instructor. Anyone interested in learning to deal with visibility issues -- including those who examine witnesses -- should attend one of Mr. Sobek's presentations."

"Optics, Lighting, and Visibility for the Forensic Investigator is an extremely useful course for forensic investigators at almost all levels. Mr. Sobek and Mr. Johnson do a fantastic job of bringing this highly technical field "down to earth." However, unlike many training classes that accomplish this by simply glossing over the hard science, these instructors use their vast formal knowledge of the discipline to make the class relevant to novice and experienced students. This class has the "meat" to satisfy an experienced engineer or human factors professional, but presents the fundamentals in a manner that novices can easily grasp."

"Your presentation was well received and the information was certainly viewed as invaluable. Based on comments I received, your presentation was timely, informative and important to the attendees. I really appreciate your effort and willingness to attend." Bob Squire, Maryland Association of Traffic Accident Investigators
I’ve been following along with your Twitter presentation and I must say, I never thought I’d be looking forward to seeing a new Tweet about such things as reflectance or candela, but I do (I haven’t wrapped my mind around the steradian, yet)....
The course is fascinating and given it’s slower pace, I have an opportunity to work through your questions and see how you arrive at the result you put forth. (I’m one of those who isn’t blessed with immediate comprehension and must go through the process multiple times figure out the process, as well as the math.) I’ve been saving each of your posts and supplementing them with step-by-step calculations for each scenario. When the end is reached, I’ll have a sizable reference.
