From Black And Whites To Gamma Cameras

By:


We live in an era of incredible technological advances. This is certainly obvious in the world of cameras. From science to medicine from the family camera to nuclear cameras progress have been amazing.

Nicephore Niepce took the first photograph in approximately 1817. He used a camera he had made himself. Later he used a sliding wooden box camera made by Vincent and Charles Chevalier from Paris, France. The photo wasn't permanent and over time faded. Niepce continued to experiment with photography and drawing on the discovery by Johann Heinrich Scholtz used a mixture of silver and chalk. The silver and chalk mixture darkens under exposure to light. While this was the father of modern day photography, a device using a pinhole or lens to project and image upside-own onto a view surface had been around since 1021!

NIcephore continued to dapple in photography and in 1827 coated a pewter plate with bitumen and exposed the plate to light. The bitumen hardened where light struck it. The unhardened areas were dissolved away. Although very rudimentary this process led to further developments in photography with daguerreotypes and collotypes.

Fast-forward a few years to the use of photographic film pioneered by George Eastman. He manufactured paper film in 1885 and then switched to celluloid in 1889. He named his first camera the "Kodak" and had it for sell by 1888. It was a very simple box camera. It was similar to our disposable cameras of today as it came pre-loaded with enough film for 100 exposures and had to be sent back to the factory for processing and reloading. This was a brilliant marketing strategy, if only unintentional. Eastman brought the camera to the common person with his box cameras, but the more expensive plate cameras still offered higher-quality prints.

Throughout the 20's and 30's camera continued to develop with the introduction of 35mm, TLR and SLR. We owe a debt of gratitude to these early pioneers. Nothing revolutionized modern cameras like the invention of digital imagery. Images are saved on digital memory cars or internal storage and no longer use film, which has become almost obsolete. Gone are the days of 24 pictures per vacation, now the average is more like 400 pictures per vacation!
Along with the advancement of cameras for personal use they have become indispensible instruments for science and medicine.

With dyes medically injected, inhaled or ingested the gamma camera can develop nuclear medical imaging to view and analyze the body. These developments have revolutionized medical imagery. From the old black and whites to nuclear medical equipment the camera is a phenomenon, it is exciting to see where it will go from here.
