With the expansion of digital camera, photography has become easy as well as increased popularity. Nowadays, the best quality pictures can be picked up on the most advanced mobile phones. As well as increasing interest, digital cameras can be purchased at a minimum. Once the camera is bought, there is no cost or trouble in the film's day. The camera gets clicked on the camera. What are all the pictures somehow? Or is the picture of all the pictures of one quality? Let's find them now
Different types of cameras according to sensor and size
Such films are taken in the film as a film, digital camera acts as an electronic object called sensor. According to the camera it is big in size. There is no reason to suspect that the larger the sensor will be better. Mobile phone sensors are small, point-and-shoot cameras, bigger than its primary, primary (entry-level) LRR cameras, bigger than mid-range SLR cameras, bigger than professional cameras. Generally, professional cameras have a uniform sensor of 35 mm film, so that they get closer quality of film. This sensor is called full-frame.
There is also a big sensor camera from Fulframe. These are used for special purposes or over-professional work. It may not be necessary to know about them.
So, behind the camera quality, the most backward mobile phone camera, no matter how many campaigns. Whatever the megapixel, no matter how much.
The next camera name point and shot camera Generally, their sensor size is 1 / 2.3 inches. Canon PowerShot, Nikon Coolpicks, Sony CyberShot, Panasonic Lumix etc. It can be as big as the SLR to keep them in a bookpack in size. Of course the size according to the lens power and other factors are bigger.
The entry-level SLR camera sensor is called Micro Four Third Sensor. The size of these cameras is a bit bigger. Their lenses can be changed. Canon Digital Rebel, Nike D3100, Sony Alpha A380 etc.
Another type of camera is made using micro four sensors. In this case, the lenses can be changed like SLR. The difference is not optical viewfinder like SLR. The result is small in size. Panasonic, Olympus, Sony have such cameras.
Midrange SLR cameras are advanced from entry level, more convenience, more expensive. There are a few other things besides sensors (mentioned in the future) in these cameras. Canon 7D, Nike D90, etc. This stage camera
Fulframe cameras are called live professional cameras. Canon EOS Mark, Nikon D700 etc. This stage camera
What does megapixel work
The meaning of mega words surely will be known. 1 thousand to 1 kilo, 1 kilo in 1 mega. That means 1 megapixel meaning 100 million pixels. When the camera is mentioned in the 5 megapixel it means that the camera will have 5 million pixels in the film.
Compare pixels to the given dot as well. The more data you need, the more space will be needed. So, the larger the size of megapixels the larger the size of the image.
The most common misconception about megapixel, the quality of the picture is better if it increases. Actually there is no relation between megapixels with image quality. Normally 6 megapixel sensors are enough for 8-10 inches print. Those who make pictures for making large size billboards are different.
What is zoom actually
Zoom importantly with a camera lens. It is known that you can take pictures of the distance. The accounts are published in millimeters. It has two values, the nearest size is wide, the telescopes are called the telescopes. Wide angle has more parts of the front footage, it becomes smaller in the telephoto, as a small part can be seen. For example 25-250mm, this means 25 mm in Wide Angle, 250 meters in telephoto. It can be written as 10x X means Wide Angle quality quality. Currently there is a point and shot camera up to 35 x (840 mm) (Canon SX30 IS).
So much so that the zoom is said to be working by the lens. There is also another topic called Digital Zoom. Software does this work. If you want to get good quality pictures then it is better to keep it out of reckoning.
The amount of zoom camera used depends on the type of image. If you have a hobby to take pictures of birds, then the better you are, the better. If it is necessary to remove images of family, nature, then zoom is not needed. As far as the picture of the flowering gardens is concerned, the better picture can not be found using telephoto.
Another lens can be opened by opening a lens in SLR cameras. Because of this, users use different types of lenses from Wide to Super Telephoto. The zoom required (300 mm +) to extract as many pictures as possible. 18-55mm lenses are available in costly SLR cameras for general work as ketlains. Experts say good portraits require 85 mm. That's why 85mm Prime lenses are available. Someone uses 135 mm or 200 mm lens to increase.
ISO, aperture, shutter speed
The image that comes in the camera sensor when the image is taken, the digital image is produced according to the front view. How much the sensor will work in light, it is revealed by a number of ISOs. For example, take 100 images of good quality images in fair light. There will be less light in the film if using ISO 50. And if you use 200 extra light will be available. Generally, if there is less light then more ISO is used, there are fewer if there is more light. In manual mode, you can set the task, or you can assign the camera to fix it yourself.
A lane is to go through a lens sensor, a portion of the window is called aperture. Increasing the aperture (the window opens more), more light goes in, and if there is more light then it is slightly opened to control it. The aperture is expressed by the number. Such as 4, 5.6, 11 etc. Small number means big aperture (high light) and large numbers mean small aperture.
Sutter speed control how long light will work. If there is more light then there is a little bit of light to take pictures. So, the speed of the shutter has to be higher. If there is less light then lesser sutrasheeds have to accept more light. A term called exposure is used to describe the amount of light. Exposure means more money, less money is less The second is expressed by the seconds. 1/400 means one-second time of 400 percent of a second.
You can specify the shutter speed or the camera can fix it according to the situation.
ISO, aperture, and sutarpid are good pictures of these three. These three changes are made in manual mode only. Highly skilled photographers do that. Others give one or two specifications, as well as adjusting the camera.
There are many uses of light here but there are many uses of aperture, sutarpid etc. In order to get good pictures in different situations, it is necessary to look at it. In the future
Auto, reset and manual
Auto mode makes all the settings the camera itself You can get good pictures without worrying about anything at all. Having trouble,
See Sutter Speed examples. You're taking pictures of flying birds. If there is more sutra speed, clear picture of wings can be found. When the shutter speed is removed, the wings will be visible as long as the wings are removed. Which one do you want? Of course, each time one can There is a speed of wanting to show the moving car images once, and all parts of the car are clearly meant to show. It may not be in Auto mode.
So, in Auto mode, you get a fairly good picture and you do not have a choice.
Here's the role of the setting made of Presets. The pictures of people, photos of very close objects, photos of the sky, photos of the night, and night photos are provided with the convenient setting for the camera. When your work is needed, turn it on by dialing it. Using the correct preset will always get good quality pictures.
And if you want innovation, if you want full freedom in taking pictures then manual mode. You can get the opportunity to use that setting right where you need it. It does not really matter as much as it seems. You can take a look at the ISO, aperture, SterSpeed etc. in the auto or preset mode of the camera. Keeping in mind, you can make the necessary changes in manual mode.
Use a camera
Know the various things in the digital camera. If you go to buy a camera, what type of camera?
There is certainly a price tag with purchase. If possible, you can choose as much expensive camera as possible. The things that will be considered are:
Make sure to use the camera maximum. You bought the best size cameras, but it was left to leave the house because of fear of traveling. I do not want such a situation. In this case, choose the camera that can be kept in the pocket. Normal point and shot camera can be enough for family pictures, picnic pictures to be taken. Between 10 and 20 thousand rupees good cameras are available in Bangladesh.
If you are interested in photography starting from photographing on different places, you can go to the superjum camera. The cameras can be found from 20 to 30 thousand taka.
And if you want to be a fully photographer, you should definitely want to get the best quality picture SLR. The initial quality SLR can be found in 40 thousand, medium quality camera is close to 1 lakh. Those who are looking for better cameras may not need advice.
There is good relationship with good camera, internal lens, image processor etc. So, buying a famous company's camera is safe. Canon and Nichon are among the best camera manufacturers. Outside of this, Sony, Panasonic, Fujifilm, Samsung, Pentex can look at them.
