Photography is direct from Greek words "Photos"; means light, and "Grafo" means painting or writing. Can be described as a process of painting or writing with the use of light as the media. The principle of photography itself is to focus light with the help of refraction so that it can burn the light-catching medium. The medium in question, namely the lens, is said to measure the correct luminosity of light, which will produce an image identical to that of the light entering the refracting medium.
To get and produce the right light intensity, a photographer can combine light intensity by changing such as:
- ISO-ASA (ISO Speed)
- Diaphragm (Aperture)
- Shutter Speed (Speed)
The combination of ISO, diaphragm & speed is commonly referred to as exposure.
The evolution of photography
The Beginning

Photography was discovered early in the 19th century. It shocked whole the world and was embraced quickly. When it was invented, people tried to understand what its purpose should be and how a photograph should look. When it first launched, instead of being something only the upper-class can have, it has now been made available for the middle class too.

The first 35mm the camera was invented is Leica and was born in Germany in 1925. At first, Leica or 35mm camera was small and could take a photo quickly. Then it became more versatile as it was improved. It had the ability to use a telephoto, zoom, and wide-angle lens.
The Polaroid
THE LAND CAMERA
In the mid-1990s, the Polaroid was invented by Edwin H. Land. The special thing about Polaroid was the ability to take a photo and print it within a minute.
The Digital Camera

The Digital Camera was created by Eastman Kodak in 1975. Soon after that, Canon, Nikon, Sony, Pentax, and any other manufacturers began working on digital cameras too, At the end of the 20th century, newspapers and magazines shifted to digital things. Then around this time, manufacturers began working on mirrorless cameras, which has become more popular among photographers.
Smartphone Camera

In this new era and becoming more digital in many things, smartphones have become popular for photos. With the advances in technology, phone cameras have been able to capture incredible images. It makes people more use this digital camera on smartphones than a separate camera.
Photography Terms
Aperture
is the opening of the lens diaphragm that allows light to enter. Aperture serves to adjust the amount of light that enters, distinguished by the "f/stops" sign.
Example: f/1.4, f/8, f/16
Viewfinder
a small hole that is used when we want to see the object to be photographed.
Focus
how when the camera sees something close, it will focus and fixate on the object. And when the camera sees a distant object it will become blurry.
Focal Length
describes the distance between the lens and the sensor or the resulting image in the film. This distance is measured in millimeters (mm).
Shutter Speed
is the part of the camera that can affect the entry of light.
Good information👍
