Camera Obscura

camera-obscuraThe word photography was first coined by scientist Sir John F.W. Herschel in 1839. The word comes from two Greek words meaning “light” (photo) and “to draw” (graphein). However it wasn’t until around 1000 AD that the first pinhole camera was invented by the Arab scholar Alhazen (Ibn Al-Haytham), who was known as the “Father of Modern Optics” by the scientific community. The pinhole camera, known as the Camera Obscura (Latin for “dark room”), was simply a closed box with a hole on one side of it where light would come through the tiny hole to create an image on the wall of the box of the outside scene that was mirrored and appeared upside down. It was often used by artists to make sketches in the field.

The first photograph was actually taken during the summer of 1827 by Joseph Nicephore Niepce using the Camera Obscura. Prior to this these cameras were used for viewing or drawing. Niepce’s photograph were called heliographs or sun prints and were the prototype so to speak for today’s photographs in using light to draw pictures. By placing an engraving onto a metal plate coated in bitumen then exposing it to light Niepce was able to make his photographs. This process took eight hours of light exposure to create.

The Museum of Modern Art has on their website some interesting information surrounding the Camera Obsura to check out.

The Museum of Modern Art (MoMA) is a place that fuels creativity and provides inspiration. Its extraordinary art collection includes modern and contemporary art.

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.
