It is a device that captures images and videos which are saved on a memory storing card. Not like an analog camera that uses chemical films for light. A digital camera creates files that can be played on any screen. The cameras installed in mobile phones are also digital cameras often called mobile cameras. Moreover, the image quality is a lot better that is why a lot of people choose a digital camera.
History of digital camera:
The idea for capturing images did exist in 1961 although there was no practical approach to it. however, in 1975 Steve Sasson used a coupling device that was charged working as a sensor to capture the image. The whole function was later digitalized. Primarily, it was used for military and scientific purposes. Later, the medical and research department were also using it.
Digital cameras were not common until the 1990s when consumers were more attracted to them.
Basic functions of a digital camera:
The camera functions as it controls the light amount and exposure time to the world with the help of a lens. With the help of external light, it can capture an image and save it.
- Controls of a camera:
To make sure that the picture we capture is in the best condition, you need to adjust the settings either manually or automatically. Here is a guide to that:
This sensor is used to determine the light intensity. The higher the ISO, the brighter image is. This can be used to compensate for the low light for some scenarios. Taking images in low ISO means a better focus on the subject and a clear picture.
It is the process of bringing the object into the frame so that the sharp photo can be captured. Mostly, photographers do it manually, but you can also adjust it to automatic settings.
It is referred to as the adjustment of the iris, the focal length of any lens. This adjusts the light amount which passes through the iris and into the lens.
- Shutter speed:
This regulates the opening and closing of the shutter with every click. It is milliseconds. This time is of the light and imaging medium exposing in the storing medium.
- White balance:
This special feature makes sure that when the white light in the real medium is captured. The image should appear natural.
It measures the exposure of sunlight in the camera. Mostly, it is done manually, so that bright light and shadow are captured how the photographer wants.
- Auto-focus point:
This additional feature is now available in most of the new digital cameras. This helps in adjusting the focus automatically according to the situation of light and image distance. Moreover, multiple auto-focus point finder is also given in many digital cameras.
Knowing the features and how it works is the first step in learning photography. Most photographers have no clear knowledge about each feature and how it works. They may take amazing pictures, but this will help them take photos in a different environment and can do creative things to take awesome images. Once you know that, anyone can start taking good shots and get featured someday.
