What is a digital camera?
A digital camera
is a camera that saves pictures in electronic memory instead of film. Because of this, a digital camera can hold many more photos than a conventional film camera. A digital camera can sometimes contain hundreds or thousands of pictures. Many use a memory card to store them. Most digital cameras can use a USB cable connected to a computer to send pictures from the camera to the computer.
Who invented the digital camera?
invented the first digital camera at Eastman Kodak in 1975. Its weight was 8 pounds (3.6 kg) and had only 100 × 100 resolution (0.01 megapixels). The image was taken onto a cassette tape, and this process completed in 23 seconds.
What are the types of the digital camera?
Digital cameras are mainly categorized according to their use, automatic and manual focus, and also price. Here are the classifications.
Is it worth buying a digital camera?
- Compact digital camera: Compact cameras are the most used and the simplest cameras to be ever seen. They are used for everyday purposes and are thus called "point and shoot cameras." They are tiny in size and are hence transportable. Since they are cheaper than the other cameras, they also have fewer features, thus reducing the picture quality. Their magnitude may be less than other cameras. The flashes are only for close objects. The preview of the picture to be taken will have less motion capacity.
- Bridge camera: Bridge cameras are usually mistaken for single-lens reflex cameras (SLR). Though they have the same characteristics, their features are different. Though they look like SLR in many ways, they work much slower than the latter. They have big size, so the fixed lenses are given very high zooming capacity and fast apertures. The autofocus or manual focus is set according to our needs. The image preview is done using either an LCD or an Electronic View Finder (EVF).
- Digital single-lens reflex cameras (DSLR): This is one of the most high-end cameras available at a reasonable price. They use the single-lens reflex system, just like a standard camera with a digital image sensor. The SLR method contains a mirror that reflects the light passing through the lens with the help of a separate optical viewfinder. In this camera, the photographer can choose the lens needed for the situation, and it is easily interchangeable.
- The electronic viewfinder (EVF): This is just a blend of big sensors and also interchangeable lenses. The image is made using an EVF. There is no complexity in mechanism like a DSLR.
- Digital rangefinders: This is a unique film camera provided with a rangefinder. With this type of camera, distant photography is possible. Though we can use other cameras to take distant photos, they do not use the rangefinder technique.
- Line-scan cameras: This type of camera is used for taking high image resolutions at a very high speed. To make this system possible, a single pixel of image sensors is used rather than a complex system. A stream of pictures of continually moving things can be taken with this camera. The data created by a line-scan camera is 1-dimensional. It is processed in a computer to make it 2-D. This 2-D data is further processed to get our needs.
If you are a more serious photographer who wants to explore shutter and aperture and improve your photography skills, it is worth buying a compact camera. Mainly a compact camera comes with manual control and a versatile lens. Here are some main features which will convince you of buying digital cameras
Digital camera's bigger sensors ensure the quality of images is better in all lighting conditions. You can determine the image quality by the lens quality and size of sensors. Compact cameras can house both. In contrast, mobile phones have limited resources due to their size. The wider the aperture, the more light can come in, and a bigger sensor means the camera should work better in low light. High-end smartphones manage to offer these, but they still aren't as good as high-end cameras, and you will pay more.
For most photographers being able to control the zoom is a valuable tool for composition and a way to capture a distant subject—many camera phones have-fixed focus lenses. To get close to the scene, you have to physically move, crop the picture or zoom digitally, increasing the pixels, so they look blurry. Some modern high-end smartphones now have optical zooms. Compact cameras are also better at shooting close-ups - many cameras have Macro modes that can shoot from 1cm away, whereas a smartphone with a decent camera can focus from 10cm.
Digital cameras let you control all the features while taking a shot. You can manually control all the settings while doing photography if you want to take your photography to the next level. Most of the smartphones take photos automatically, or they have very few settings to play with. Its always better to control what you are photographing and experiment with action shots and depth of field.
Best budget cameras at a glance:
Are you trying to find the best affordable camera for yourself? Whether you're looking for your first camera, something cheap for a holiday, or even a gift for a young photographer, you don't need to spend massive amounts to get a powerful camera these days. Let's take a look at the best affordable cameras you can buy.

|Sony Cyber-shot RX100 III
|Canon EOS Rebel SL3 / EOS 200D Mark II
There are all types of digital cameras available these days, so the deal is to find the one that satisfies your needs and budget. If you are buying your first digital camera, the jargon and technology are different from those for film cameras. First, what kind of photographer are you? Do you want total control over the picture taking process, or would you instead direct the camera and push the shutter button? Then it's also helpful to determine what you want to do with your pictures. Do you want to put them online or send them through email, or do you want to print them, and if so, how big do you want your prints? If photography isn't your desire, and you want to have pictures, buying a simple point-and-shoot digital camera
is reasonably best. It has automatic settings, so all you have to do is aim the camera, press the shutter and voila! Ready-to-use picture! However, if you fancy more control over the picture-taking process, try buying a mid-range digital camera. There are "prosumer" cameras midway between point-and-shoot cameras and digital SLR cameras for the more serious hobby photographer. They give better lens quality and normally more features than a point-and-shoot, though those little cameras can come pretty loaded these days!
