DSLR camera has come a long way. There were days when there were bulky big cameras with blinding flashes. Getting a family photo was a family outing in itself.

Everybody would dress in their best and go to the nearest photo studio. The camera man would ask everybody to huddle and smile.

The cameraman will disappear in a black colored cloth behind the camera and then there was a loud bang and a flash and the picture was taken. The photo required days to develop and then you would get it.

The process of developing the photo was even more complicated with the developing process taking place in dark rooms, where no light was allowed lest it spoils the photo.

This article will help you in knowing everything you wanted to know about buying a camera.

Gone are those golden days, now you have cameras everywhere. Be it your mobile phone, digital cameras, tablets or laptops, even your home Cctv has a camera you have cameras all around you. Yet, how many have we wondered how these cameras actually work. What is the meaning of all the jargon and acronyms and other information that we get to see on the cameras? The booklets that accompany these devices are of no help either, in fact, they add more to the confusion.

We have put together this guide to guide you through the jargon jungle of the camera world and enlighten you so that you are more knowledgeable when buying a new camera.

Before we start explaining you the basics of the camera, one should keep in mind that whether it is the small camera on your laptop or the most professional cameras from Nikon or Canon, the basic principles remain the same.


Pixels or picture elements are the tiny dots that combine together to form an image. An image consists of millions of pixels. These dots or pixels are so small that from a distance they are just indistinguishable, however, if you zoom much into the image, you can see these small dots that make the image. Pixels are the building blocks of digital images and form the first parameter when searching for a good camera. Think of Pixels as dividing a foot long ruler into 1,500 smaller increments as against 150 increments. The ability to measure more minutely increases with 1,500 as compared to 150 measure. Higher the pixels density, clearer would be the image and finer the details it can capture. In the past many vendors have settled on 18MP as more or less the industry standard for entry-level SLR cameras. A rule of thumb on deciding on the Pixel rating for your camera can be decided by thinking about where you intend to use your photographs. If the photos are meant for magazines or advertisements and you intend to use enlarged and zoomed images, opt for higher pixel ratings to avoid pixel breakage. Bear in mind, though that more the pixels you opt for, heavier the images.


The most basic term you will often hear from a professional photographer is “exposure”. In the very basic term, exposure simply means the brightness or the darkness. In photography context, in order to get the best of the photographs, you need to be sure that you are neither “underexposed” nor “overexposed”. The photograph exposure should be just right to capture the best photo. When you are looking at the specifications of the camera, the exposure settings of the aperture should just be right. In simple terms, the aperture is the factor that controls the area over which light can enter your camera.

Shutter speed

The camera’s shutter speed determines the speed at which the sensor opens or closes to the light. This determines how long the light is allowed to enter the camera. A faster shutter speed will mean a shorter exposure time.

Think of exposure time as the duration for which the camera lens remains opened to allow the external light to enter inside the camera. So if one increases the exposure times, the duration for which the light is entering the camera also increases. If you want to take photos in low light, the shutter speeds are in the range of  1-30+ seconds and if one wants to take photos of extremely fast motion, the shutter speeds should be in the range of 1/1000-1/4000 seconds.

In order to get beautiful photos of a gentle waterfall, one may need a slow shutter speed, whereas, for extremely fast split second capture, one may need fast shutter speed. So if you think your eyes as the camera (it is true, our eyes are the most advanced cameras), then if you try winking your eyes very fast, you would be imitating a faster shutter speed.

Aperture setting

If you have a bigger, larger window in your room, the amount of light that can enter the room is more as compared to a smaller window. This is the same with a camera. The higher the aperture of the camera, the more light is allowed to enter through the lens. The aperture is specified in terms of f-stop. The area of exposure decreases as the f-stop increases. So f/2 would be larger than f/4 which would, in turn, be larger than f/8 Generally as a rough rule, for lower the f-stop shallower the depth of field and higher the f-stop, higher the depth of image field giving you that soft background effect.

So f/2 would be larger than f/4 which would, in turn, be larger than f/8. f/2 is about 4 times larger than f/4 which is 4 times greater than f/8. Also f-stop uses weird numbers in between like between f/2 and f/4 there is f/2.8 rating or f/5.6 to denote rating between f/4 and f/8. Look at the denominator of f-stop. If it is higher than the camera sensor collects more light.

Generally as a rough rule, for lower the f-stop shallower the depth of field and higher the f-stop, higher the depth of image field giving you that soft background effect.

International Standard Organisation (ISO) specifies how much sensitive, the camera lens is to the light. If the lens has a higher ISO, you can take pictures from it without needing a flash. However, you may see some noise in your photo. So higher the ISO, noisier the image will be and vice versa. Most cameras have ISO settings of 100 to Auto. Check your camera’s manual to see how you can change the ISO settings.

Mirrorless camera vs DSLR camera

Recently, there have been some good technological advancements and mirrorless cameras have started coming to compete with the more traditional DSLR camera. These mirrorless cameras have more or less the same features as their DSLR counterparts and are coming in the same look as DSLRs. They are light in weight and quickly gaining popularity. However, if one investigates a bit deeper, will find that these mirrorless cameras have sensors which are smaller than the DSLR camera. Now what this means is that the image that one shoots from these mirrorless cameras lack the depth as well as the clarity that one gets in low light conditions. The auto focus speed that you can find in DSLR camera is lacking in mirrorless cameras.

DSLR Camera and Point/shoot camera

Digital cameras come in 2 types. One is the point and shoots cameras and the other are the DSLR (Digital Single Lens Reflex) camera. There is a mirror behind the lens which helps in reflecting the image through a prism (this is why they are called reflex) from a mirror reflection so that the image can be seen through a viewfinder.

In an SLR, the photo film has the shutter and a mirror in front of it. When a photo is clicked, the mirror goes out of the way and the shutter opens exposing the film to the view. The point and shoot cameras are the fixed lens cameras with no mirror in between the film and the shutter with a much smaller sensor as compared to DSLR camera. They are built to be small in weight, fast and silent. Stick in your jeans pocket and you are good to go.

The point and shoot cameras have the sensors that are always receiving the image on them. So the sensor sees what you see in the viewfinder. Computer algorithms allow taking sharper focused images by reducing the blurriness in the exposed view. However, there is always the lag because the images are processed and then shown on the viewfinder. This is not the case with SLRs, where it is much more complicated, thanks to the larger lens and a larger aperture, optical viewfinder sees through the lens using a number of movable mirrors.

The point-shoot cameras are small and compact and offer megazooms of 10x, 20x in one lens. However, the lens tends to have limited aperture and functionalities. DSLR camera, on the other hand, have interchangeable lenses. This helps in getting extremely clear professional images. you can have the whole collection of lenses available for DSLR camera to match the megazooms setting you may want for your photos.

The point and shoot cameras such as the popular Sony Cybershot DSC-W830/S are smaller cameras, whereas the DSLR camera are the larger ones like the Canon EOS 1200D. DSLR camera are more popular among the professional photographers, but recently, many hobbyist photographers have started moving towards the Digital SLRs because of the wider options and better professional quality images they deliver.

How to select the best camera

Apart from the above points, there are various important factors that you may consider as a layman when buying a camera for yourself.

Budget: Due to the recent advancements in technology, many point and shoot cameras have come out in the market which takes images at par the expensive DSLR camera. Most of us believe that one might get better photos from the expensive cameras, but it is not always true. The real truth is that buying an expensive camera will not improve your photographs just as buying in on an expensive laptop will not improve your knowledge skills. one should know how to effectively use a camera, be it an inexpensive p/s or the more expensive professional DSLR camera.

Sensor size: These are the megapixels that the camera allows you to take your images in. the greater the MP, the more you have the ability to zoom into the image and see the finer details.

Modes offered: Go for the cameras that are assisted by a good software so that they offer such features as different scene mode, shutter priority modes.

Battery and Memory: Getting a world class camera won’t do you any good if the battery does not have a longer life and the camera does not have larger memory. It is always a good idea to choose batteries that are rechargeable as against the standard AA batteries. Buying an extra set of batteries is always a great idea especially when going on an outing.


Photographs are taken to store and record memories and recently, with the help of digital cameras, this has become so much easier. Anyone can take pictures, but few know how to take better photos. Hope this article will serve as a buying a dslr camera guide and help you in getting a better understanding of the various terminologies and jargon that hound you when you go out to buy yourself a good digital camera. Knowing these facts will not only help you in operating your cameras better but also assist you to take better pictures.
