Parts of a Camera



Camera is made up of many parts, but there are a few in particular that we want to look at as they are the most important. Here’s a basic overview of the parts:

1.The body
The body is what you see on a camera when the lens is unmounted. While body has little effect on the quality of your photos, it does affect things like ease of use and comfort. If we can’t hold it properly the quality of the images will be poor.

2.The lens
The lens is the eye of the camera. It’s a very complex instrument. Different lenses can provide many different features, so it’s important to know the differences between them.

3.The sensor
The sensor is basically the digital equivalent of film. It means that, like film, the sensor is exposed to light that comes through the lens and it records that exposure. The exposure is then processed and saved to flash memory (generally an SD or Compact Flash card). The caliber and size of the sensor are also very important, as these things significantly affect the quality of your photos.

4.The flash card
Flash card is where you save your images. Flash cards range in read and write speeds as well. A slow card can significantly degrade your camera’s performance.

5.The battery
Camera is just like any other electronic devices. It needs energy to work. So battery is an essential part.

Camera - SLR & DSLR



Camera is a tool, a device for recording visual images in the form of photographs, film, or video signals. We know its use. It is actually a box that controls the amount of light that reaches a piece of light sensitive film or other surface inside. The original cameras did not even have a glass lens. 

The first cameras used a tiny hole in the front of the box to allow in light and to focus the image onto the viewing surface. This is the same principle as when children punch a pinhole into a piece of paper in order to watch a solar eclipse projected through the pinhole and onto the ground.

The First Photograph: In 1827, Joseph NicephoreNiepce made the first photographic image with a camera Obscura.



SLR Camera
Single lens reflex cameras (SLR) use a mirror and prism system to allow photographers to accurately see the image that will be captured. This system uses one optical light path whereas previous cameras had two, one through the lens to the film and the other to the viewfinder.

DSLR Camera
DSLR stands for “Digital Single Lens Reflex”. DSLR is a digital camera that uses mirrors to direct light from the lens to the viewfinder, which is a hole on the back of the camera that you look through to see what you are taking a picture of.
