Moments: The Evolution of Cameras.

Photography. An art form invented in 1830s, becoming publicly recognized ten years later. Today, photography is one of the largest growing hobbies in the world. Photography has come a long way in its relatively short history. In almost 200 years, the camera developed from a plain box that took blurry photos to the high-tech mini computers we use in our DSLRs and smartphones today.

The story of photography is fascinating and it’s possible to go into detail. Today we take a step back and look at how this fascinating technique was created and developed, because proudly knowing the past is the primary way to create a great future.

Camera Obscura

The basic concept of photography has been around since about the 5th-century B.C.E. It wasn’t until an Arabian scientist Hassan Ibn Al-Haytham developed something called the camera obscura (which is Latin for the Dark Room) in the 11th-century that the art was born.

Camera Obscura is essentially a dark, closed space in the shape of a box with a hole on one side of it. The hole has to be small enough in proportion to the box to make the camera obscura work properly.

 

 

 

 

 

The Invention of the Camera

The first photo picture – as we know it – was taken in 1825 by a French inventor Joseph Niepce. It depicts a view from the window at Le Gras.

the photo had to last for eight hours, so the sun in the picture had time to move from east to west, appearing to shine on both sides of the building in the picture.

In 1839 Sir John Herschel came up with a way of making the first glass negative as opposed to metal. The same year he coined the term Photography deriving from the Greek “fos” meaning light and “grafo” – to write.

Finally, after decades of refinements and improvements, the mass use of cameras began with Eastman’s Kodak’s camera. It went on to the market in 1888 with the slogan “You press the button, we do the rest”.

In 1901 the Kodak Brownie was introduced, becoming the first commercial camera in the market. The camera took black and white shots only.

The first 35mm still camera developed by Oskar Barnack of German Leica Camera. Using a film for colored photos.

Technologies

TLR

The twin lens reflex (TLR) camera started in 1870. This type of camera has two lenses. The top lens composes and focuses. The bottom lens actually creates the shot.

 SLR

The Single Lens Reflex (SLR) camera uses optical film to capture pictures and images. The mirror and prism system used in the SLR cameras send the light through the lens of the camera

Mirrorless Camera

Just Like Mobile Phones no Mirrors are used to view the photo Using the sensor directly to view the photo and record it if needed

Camera’s Principles

Exposure  

Exposure refers to the amount of light that enters the camera and hits the digital sensor. Basically, it is a measure of how dark or bright a photograph is. 

 

 

 

 

 

Aperture

The aperture refers to the size of the opening in the lens through which the light

enters the camera. The size of this opening can be adjusted

and the aperture size is measured in f-stops.

 

 

 

 

 

 

 

shutter speed

The shutter speed refers to the length of time the opening in the

lens remains open to let light into the camera and onto the sensor.

 

 

 

 

 

 

 

ISO

The ISO refers to how sensitive the digital sensor in your camera is to light. The lower the ISO number, the less sensitive it is to light. Setting a higher ISO number increases the sensitivity of your camera sensor to light.
