You must have seen that nowadays, if anyone buys a new mobile, everyone asks him how many megapixels the camera is. We start the new mobile phone only by taking a photo. Some people are such that they do not have much difference with the other configuration in the mobile, but they just need good quality and high megapixel room. If you also want to know what is DSLR Camera then the answer to your question will be found in this post.
Mobile companies want to give more and more features in the form of camera for their customers, even with 2 cameras in the front, flash lights have also been given to take selfies. But when it comes to high quality HD photos, then the cameras used in mobiles fade.
No matter what the ceremony is going on and people are gathering at one place and participating in that ceremony, you must have seen the photographer there. So that that photo can be saved and the memories of it should be refreshed sometimes. Be it a seminar or a party, there is a competition between people to get photographed. Today, if some old friends meet at one place, then everyone takes a lot of sari photos and keeps it with them to remember that day forever.
The younger generations now know a little about the DSLR camera, whether they have used it or not. Digital camera used to be popular for taking photos among most people, but DSLR has been taking the place of digital camera for some time. The quality of any photo taken in DSLR camera is of very high quality compared to all other cameras.
Even if mobile companies use the best camera, they cannot match the quality of DSLR. Now it becomes important to know what is there in the DSLR camera that sets it apart from all the other cameras. What is DSLR Camera? Also, in this post, we will also know how the DSLR camera works and what are its parts.
What is DSLR Camera
A DSLR camera is a digital camera designed to combine the optics and mechanisms of a single lens reflex camera with a digital imaging sensor. This is exactly the opposite of a photographic film. In this type of camera, you see exactly what is seen in that lens. Lens can also be changed in this. With the help of this, we can take photographs of very high quality as it has very large size image sensors. DSLR camera has lag ie lag time zero, it is ideal for action photography.
In this, we can take any kind of photo, we can also take a good quality photo of a car that is slow and slow. If you are never able to take a photo, then maybe you are lacking, your camera is always ready. Till before 2005, only professional people used to have Digital SLR camera, but since then its price has dropped continuously. This is the reason why today DSLR camera has become the first choice of most people when it comes to photography.
DSLR Camera Full Form of (DSLR)
The full form of DSLR is "Digital Single Lense Reflex".
It is also called Digital SLR.
What is the parts of DSLR camera
In this, what are the parts that separate it from others and here also we will know what are the functions of these parts.
Probably very few of you will know what are the parts in DSLR camera and what is the function of these parts. Let us know this in detail.
Lens
Lens is very important part of the camera. Light enters through the lens and this is where the process of photographing begins. The lenses are attached to the camera in 2 ways, they are also fixed and interchangeable. The configuration focal length of the lens is kept as required in the aperture camera.
Reflex mirror
Reflex Mirror is the part inside the camera where the reflex of the photo is visible which is also called the image. It remains behind the lens. The light that goes in through the lens falls on the mirror, which is absorbed by the mirror.
Shutter
Shutter is a mechanism used in the camera in which shutter is released and it controls the light inside the camera. The quality of the photo also depends on the shutter speed. If the shutter is closed at a slow speed, more light goes into the camera and when the shutter is closed quickly, the image produced gets more light and due to this the photo gets good birghtness, while the light becomes dark due to less light. is. For this reason, the speed of shutter release is kept moderate by balancing it.
Condenser Lens
Condenser Lens use 2 convex type lenses. The main purpose of using these lenses is that the light goes in a straight line inside the lens of the camera.
Image Sensor
When the light goes inside the camera and the shutter is closed, the image sensor captures that image. In this, the work of the sensor is very important because the larger the image sensor, the better will be the quality of the photo. When the image sensor is of small size, its ability to capture is also less.
Focusing screen
Using this, we can see how the photo we want to take is looking like. Focusing screen shows us the preview of the photo, and which area of the photo to focus on, it is known by looking in it.
Viewfinder / Eyepiece
Viewfinder is available in all types of cameras, even in some digital cameras. This is the same screen on which we see the image with our eyes while we are able to see the image coming on this screen. Viewfinder used to be used in earlier times, now LCD screen is used instead.
Pentaprism
Pentaprism is a 5 sided reflecting prism that has the ability to bend the beam of light in 90 degrees even if the light is entering it at any angle. The beam of light is reflected 2 times inside the prism. The purpose of this is to keep the light in a straight line.
Flash
Nowadays flash is used a lot in doing photography. When there is not enough light to take an indoor photo, the flash will work automatically when you take the Poto and adjust the light, which makes the image clear.
Memory card
Earlier cameras used film reels but since the camera came memory cards are used in all cameras to store all photos and videos.
Working Process of DSLR Camera - How does DSLR Camera work?
When we look at the viewfinder / eyepiece or LCD screen on the back of the camera, whatever appears in it reaches it through the lens. This means that whatever you are seeing in it, the camera is going to capture the same. The light coming from any scene we want to photograph goes to the reflex mirror inside the camera chamber, which is attached at a 45 degree angle. Now it sends the reflex mirror light forward in 90 degrees i.e. vertically to an optical element, this element is known as Pentaprism. Now the vertical light which turns in the 2 mirror Horizontal direction present in Pentaprism which reaches directly into the Viewfinder.
When you take a photo, the Reflex Mirror rotates upwards and blocks the vertical path and straightens the incoming light. After that the shutter opens and the light reaches the image sensor. Until then the shutter The image sensor remains open for as long as it takes to capture the photo. After this, the shutter is closed and the reflex mirror goes back in its place 45 degrees so that the light can be redirected from there to the viewfinder.
Now from here the complex image processing that takes place inside the camera starts. The camera processor takes the information from the image sensor and converts it to the format as per the requirement and then stores it in the memory card. This process takes very little time to complete and there are some DSLR cameras that complete this task in 11 parts of 1 second.
So this is the process under which DSLR camera works and we get high quality photo as output.
How to drive a DSLR camera and take a photo
If you have taken a new DSLR for yourself and have just taken it out of the box, then you must have seen a lot of buttons. Although there is a manual given to use it with the camera, but no one likes to read it. There are very few people who know how to use it. If you are also among those who do not have information about DSLR, then let us know this.
Master shooting mode
When using DSLR, the first thing comes to shooting mode. In Shooting Mode, you will see some such options AUTO, AV, P, M. Now the camera will behave according to the mode you select from it i.e. when you select AUTO, the camera itself will determine the exposure in which aperture and Shutter speed is also included. In other modes, you control yourself.
Understand ISO
ISO is a type of measurement that describes how sensitive your camera's sensor light is. ISO sensitivity is represented numerically, with the lowest sensitivity being ISO 100 and the maximum ISO 6400 High Sensitivity.
High sensitivity requires more light so that the exposure can be provided as per the requirement, whereas in high sensitivity, less light provides the required exposure.
Learn the Exposure Triangle
It is very important for you to know that aperture, Shutter Speed and ISO are all part of Exposure Triangle. They control the light going inside the camera according to the given exposure of the camera. These three are connected to each other so that the camera can be completely controlled. Setting one of these also affects both.
Master metering
You have already learned that the camera calculates the exposure according to the available light. The camera always calculates the average exposure. It accesses the entire scene even if the area is light or dark area. Generally there are 3 types of metering modes that you can choose.
Average - The camera measures the entire corner of the image.
Center Weighted - Measures the exposure in the center area of the viewfinder.
Spot Metering - Uses a very small portion of the camera area. This is equal to a very small circle in the center of the viewfinder which is equal to 5% area of the viewfinder.
Exposure Compensation
In a small shape close to the shutter, you have a +/- button as written. This is a very useful feature that needs to have knowledge. This can increase and decrease the meter reading according to the brightness of the scene.
Learn About Focussing
Even if you keep any shooting mode and you will have any ISO set but the photo will not be good unless you focus on the image correctly while taking the photo.
Understand File Size and types
In this, when you remove a photo, its quality also depends on what size and format of your photo you have selected. When you choose the highest quality in it, then you get the best quality photo. If you choose a lower size then the quality of the photo will not be good.
In short
Smartphone is usually with every person and the practice of double camera has also started. No one even knew what a selfie was before the arrival of the smartphone. But taking any number of photos in the smartphone does not give satisfaction. Everyone wants to have a high quality image, so today we have to know what is DSLR camera.
Through this post I have tried to make you understand the complete details of DSLR camera in simple language. Here you also know what are the parts in DSLR camera and also know how to take DSLR photos? You also know how the DSLR camera works. If you are having any kind of trouble in understanding, then you can tell us by commenting.
