If you want to buy a digital camera then you should know what the specification of a camera means. But before going into that deep technical knowledge we should first know what are we will do with that camera. You will buy it today because you think that photography is your passion, you quite enjoy doing it, you want to do travel photography just because you have seen one video of a person with a nice background and more like that. But once you will buy it you will start giving “Excuses“ that you don’t have a camera with a better lens and this and that and blah blah blah blah… A nice set of excuses will be there for you.
So, regarding those post-buying excuses, we should know some pre-buying knowledge.
The basic definition you will get nowadays of photography is that “It’s an art of showing what you feel but in a picture.”
A great man once said that “Photography is an art in which you draw the feelings of the object by recording not only the light but the real soul of that object”. And you will get to know the name of that great person at the end of this blog.
You will have your different definition of photography and I would love to know those definitions (comment if you have a different one).
If we will talk about the technique in deep then I will not be able to connect to all the readers. So, it is a process in which we record the light which enters through the lens of a photosensitive material and it produces an image. In earlier times we used photographic films but now we use the Electronic sensor in place of it. And now by doing some adjustments in the settings like the opening of the shutter (shutter speed), the sensitivity of the digital sensor (ISO), the amount of light passing through the lens (aperture) you can control the image.
Now, we should also know some basic technical specs which you can watch before buying a camera for yourself.
The number of pixels a camera can record in a single shot and in digital cameras we use megapixel to show that amount. But it becomes irrelevant when it comes to image quality. The high megapixels on a small camera will produce a noisier image because you are telling the camera to store such large information on a much smaller space. But as the technology is developing it is becoming a less than a problem.
A sensor is that film which gets exposed to the light when the shutter is open. There are many types of sensors but there are 4 that matters the most right now.
These are very small in size but they carry a lot of Information and sometimes it affects the image with unwanted noise. For these sensors, you will need to have a better image processing. On this small size of the sensor, it’s difficult to capture all the information from the light so to compensate that thing we need to have a better image processor for that.
When we can’t have full-frame DSLRs but still want a better picture, in that case, we use this sensor. In this, we can change lens and can have a better picture because of the design of this system. Olympus and Panasonic released it in 2008 and from that time we have come across the mirrorless camera.
The sensor which you will find commonly in most of the DSLRs is APS-C Sensor. It is neither full frame sensor nor point and shoot sensor. Though it will provide a clear image than point and shoot sensor there it has a disadvantage called “Crop factor”. It means if we attach a 28mm lens then we will get the cropped image of 45mm lens. So, it generally magnifies the image by 1.5 times the actual focal length
Full frame means it digitally equals to 35mm film. It comes mainly in the high-end DSLRs like Nikon D750, Canon 5D or 7D series. These sensors do not have any crop factor like APS-C sensor. And which will record more light and can also provide a shallow depth of field like a 35mm film camera. As it is a larger sensor than other sensors so it will also provide high-quality images.
When we talk about the quality of the image then the image processor plays a vital role. If we are only clicking in RAW then image processor doesn’t play its role as it edits the clicked picture but in the RAW format, we get the actual recorded information without any editing. Image processor edits the image when we click in JPEG format using its own algorithm. Not only editing it also affects the speed of the continuous shoot in JPEG format as it edits every individual image and that depends upon only on the image processor.
Lens plays a vital role in photography. There are two types of lens. In point and shoot, there is a fixed lens. And in another camera, there is the interchangeable lens. There are only a few specifications that can tell us about the quality of the image and also the amount of depth of field. The amount of light to enter the camera is allowed by optics. Apertures are rated in f-stop on the specification. If on the specification there is f/2.8 written then it tells you about the opening of the lens. Wide apertures are generally rated as f/1.4, f/1.8 which are used when you need more depth of field and more light.
So, we have discussed some technical terms of photography but it is an art which is done by an artist. The great artist I was talking about is Mr. Sachhidanand Jha (oh! That’s me :P).
Keep clicking. sharing. loving.
