How it all started?

The first permanent photos were created and began the history of photography in the early nineteenth century.The very first colour photograph was created by photographer Thomas Sutton In 1861 using the addictive colour method who was instructed by the James clerk maxwell, the 19th century mathematician.

But before all this there were a number of devices that were used for the same principle,for example before the very first permanent photographs were created there were things like camera lucida,camera obscura and the pinhole camera.Although these images were not permanent they all used the properties of reflection to create images on a surface and most importantly,light.

The first permanent photograph was created by French invented Joseph Niecephore Niepce in 1826, Simply by using a pewter plate coated in bitumen, the material hardened after a eight hour light exposure, the material that stayed soft Was washed away,The plate polished, and there the negative image was created. The plate was then inked and was used to Print paper photographs.

What makes a photograph?

There are many things we need to make a photograph, but the most important one is light, and of course an actual camera. We need light for everything and making a photograph is one of them. A photograph is simple a moment frozen in time.
Natural light photography.
The basic steps of "what makes a photograph"
- press the shutter release button which opens and closes to the light.
- the light reflected of the object is recorded.
- light hits chemical solution on camera film ( silver Halide crystals)
- rays are refracted through the camera lens.
- causing change on photographic film and produces an inverted negative image.
- chemical record is very stable and can be developed, amplified and modified.
- then produces a positive print from the negative object.

What is light?

Light is an electromagnetic radiation that is visible to the human eye, the radiation happens in waves and particles. In simpler terms light happens when all colours from the electromagnetic come together to make white,being light. Visible light is reflected back off an object and is then processed by our eyes and brain.
A stream of massless proton particles each travel at the speed of light using wavelike properties is another way to describe electromagnetic radiation.
