Blair Tourograph

The Tourograph was introduced in 1878 by a man named Thomas Henry Blair and was initially produced and marketed by the Scovill Manufacturing Company through their American Optical Division. Later it would be owned and controlled by The Blair Tourograph Company. It contained everything needed for photographers to expose and develop wet collodion plates. Blair created it to be a complete portable photographic system.

When the first Tourograph was introduced it was during a time when the wet collodion method was ending. A new method was on the horizon that used dry gelatin plates and so Blair revamped the Tourograph to keep up with the newer technology. In 1880 the new version appeared and was a completely different design. Three versions of the newer Tourograph were produced and it was ultimately replaced in 1883 with the Lucidograph.

The Tourograph was designed to enclose all the workings needed inside the wood box that a photographer would need to take a picture and develop it. It was a little cumbersome to use as there were steps to take in physically manipulating the camera itself order to produce a picture.

Assistant Executive Director Department Chair Investigation & Research Education Resource Photography & NPS Photography Team at NPS of Texas
Sheri has always had an interest in the paranormal – from watching different paranormal shows over the years to having déjà-vu experiences throughout all her life that she has tried to put an explanation to. When her dad passed away in March 2010she began her journey into the paranormal. She has had several encounters over the years since starting in the field & takes more of an “old school” approach to her research in the paranormal. She is a supporter of today’s modern technology being used on investigations & encourages the use of various tools on investigations. She is always looking for a new ‘old school’ method to try on investigations & employs the use of trigger objects in an effort to get a response. She became fascinated with the pendulum after using a set of original jailer’s keys as a trigger object on an investigation at a local historic jail & they began to sway in response to questions.She is a huge proponent of education in the paranormal field choosing to debunk things immediately by trying to recreate situations & experiment to find logical answers to things that have happened or been captured in photographs or on video in an effort to prove or disprove paranormal activity. She & her team focus on private residential cases as well as educating the public on paranormal investigation & research. You will often find them assisting & consulting with other teams on theircases. Sheri is a certified paralegal and Notary Public for the State of Texas. Her professional background includes working in the legal field, sports marketing, event coordination & business management. She serves as Assistant Executive Director of NPS and the Department Chair overseeing Photography and the NPS Photography Team.
