The Sliding Box Camera

sliding-box-cameraThe Sliding Box Camera was first introduced commercially in 1839 by Louis Daguerre along with daguerreotypy – the first photographic process. The plates this camera used measured 6 ½” x 8 ½” and were known as “whole plates” which became a standard for many years. The Sliding Box Camera consisted of two wooden boxes with one sliding into the other and the outer box being attached to a baseboard. Focusing was done by sliding the inner box until the subject was focused on the rear ground glass screen then a brass nut was used to lock it in place. Fine focus was adjusted using the lens rack and pinion. With the screen image being dim, the photographer would usually work under a dark cloth.

Sheri Collins

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. Sheri leads the Investigation & Research Education Resources for NPS which provides information, links, & articles surrounding education in the paranormal field. She also writes articles periodically for the NPS’ website that are tied to photography & education. She is one of the founders of NPS of Texas, a paranormal research & investigative team based out of Dallas, Texas.
