Camera type and the lens type


Camera Camera

The world's first photograph was taken by Nussafor Nipse in 1826 with a wooden sliding camera, which was made by Charles and Vincent in Paris. The photo taken with this camera blurred after some time. Subsequently, in 1724 AD, John Hinrich Schultz made a blurred silver and chalk mixed camera in the presence of light. Arab and Iraq scientist Ibrah Alhatham created a light-sensitive camera using a device.

This camera used a lens to bring the image to the screen. Roger Bacon used a special type of material in the camera and drew a blurry picture of clouds. In 1604 AD, mathematician and device inventor Rainers Gemma Frecious tried to see the solar eclipse by this camera and in 1558 AD, GB Della Porte created the first method of photographing.

Camera type and the lens type. Before the creation of photographic cameras, it was the practice to draw the picture by hand. In the past, the size of the camera was the size of a room, with more than one person standing. Gradually the size of the camera became smaller. The first small and low-load camera was manufactured by Johnson in 1665.


Camera operation

There is a lens on one end of the camera and a means of applying photosensitive film on the other end. SLR single-lens reflex SLR single-lens reflex cameras are most preferred for taking photos. In such cameras, the image is visible in the viewfinder from the same lens and on pressing the shutter, the image is formed on the film.


Camera type and the lens type

Whatever the photographer sees in the viewfinder of this camera, the same picture is printed on the film. Photocomposition, depth of field can also be combined in these cameras. The superiority of good cameras is determined by the power of their lens. The most important part of any camera is the lens itself.

 The lens itself reflects the image on the film. The lens has the property of converting the rays of light at one point. Light rays pass through the lens and meet at another point. This image is formed by the same properties of the lens.


Lens types according to Angle of View

According to Angle of View, there are Normal, Wide, and Narrow lenses.

Normal Lens

The normal image made by this lens is equal to the diagonal of the size of any specific camera body. Generally, 40 mm and 55 mm lenses are called normal.


Wide Angle Lens

The lens has more angle view in this category. Through these lenses, a larger image is made than what a person's eyes see. This type of lenses has a very short focal length. Its biggest feature is that even though the distance between the subject and the camera is short, it can cover more parts.


When the photograph is to be taken in a place where the distance between the camera and the subject is very short, the photo of the entire subject can be easily taken using a wide-angle lens. This lens is especially useful for groups and action photography in moving subjects.


Narrow-Angle Lens

This lens is made up of less than what our eyes can see of a subject. The main feature of this lens is that this lens is used when the subject is away and the photographer cannot take a photo by taking his camera and approaching it.


Types of Camera

Compact digital camera

Compact cameras are made in such a way that they are small and portable and are mainly useful for casual and snapshot use, hence point cameras.


Generally, the smallest compact cameras with a thickness of less than 20 mm are usually designed in such a way that they are easy to use, provide advanced features, and have a compact and simple picture quality. Most compact cameras have a built-in flash, whose power is generally low. Typically a 6mm diagonal image sensor is used in these cameras to reduce costs and reduce size.


Bridge camera

The sensors of these cameras are much larger than other types of cameras. Their diagonals typically range from 18 mm to 36 mm (crop factor 2, 1.6, or 1). This gives them excellent low-light, low depth-of-field in a given hole, and large size. Each major (DSLR) manufacturer also sells different types of lenses, which are manufactured specifically with the idea of ​​using them in their cameras. This makes it easier for the user to select the most suitable lens designed for application wide-angle, telephoto, low light, etc., each of its lenses does not require its own shutter behind the mirror because the DLSR has a front of the imager Focus-plane shutter is used.

 Electronic Viewfinder, interchangeable lens camera

The final round of 2008 saw the introduction of a new type of camera, with interchangeable lenses of DSLR cameras and larger sensors connected via an electronic viewfinder or with a live preview system of compact cameras on the rear LCD. Because of the removal of the mirror box, they are simpler and more compact than DSLR cameras. As of 2009, the only such system is Micro for Thirds, whose components are derived from the Four Thirds DSLR system.

Digital rangefinder

Resfinder is a user-operated optical system used to measure the distance of objects, once used in film cameras. Most digital cameras measure the distance of an object automatically using acoustic or electronic technology, but It would not be fair to say that they have a rangefinder. The noun res finder also sometimes means a rangefinder camera.

Line - Scan Camera

A line-scan camera is a device that consists of a line-scan image sensor chip and a focusing mechanism. These cameras are often used only in industrial locations to capture the continuous flow of moving material. Unlike video cameras, line-scan cameras use a table of pixel sensors instead of their matics. Line-scan camera data has a frequency, under which the camera performs the task of scanning, waiting, and repeating a line. Line-scan camera data is typically processed by a computer to collect one-dimensional line data and create a two-dimensional image. The data of the collected two-dimensional images is then processed by image processing to serve industrial purposes. Camera type and the lens type

Integration of digital camera

Many devices have inter-built or inter-integrated digital cameras. Mobile phones often include digital cameras. Other small electronic devices such as PDAs, laptops, and BlackBerry devices often have a mandatory digital camera similar to some digital camcorders. Photographs are a medium of communication.

Camera type and the lens type

The person guesses many things just by looking at the photo. The photo has a profound effect on the mind of the person. Such a person does not remember by listening, much as an image is formed by looking at his memory. He can remember those things for a long time through pictures. Changes are being made in cameras and their operation is also getting easier. As the camera becomes smaller, it is becoming easier to operate it.
