BUYING GUIDE FOR CamERa
MAIN FACTORS OF A CAMERA:
ISO Sensitivity is simply the measure of your camera’s ability to capture the light. Digital cameras use the light that falls on the sensors and convert them into electrical signals. The higher the ISO, the faster is the shutter speed which means that the camera captures a low-light image with perfection and raises its light quotient which leads to getting a perfectly captured image.
When the image sensor is exposed to light, the exposure is increased. The more the image sensor gets light, the higher the exposure. DSLR cameras have auto-exposure systems that automatically produce photographs with optimal brightness. While there are exposure settings that can be done manually, every camera except DSLRs have auto-exposure setting so that they can produce optimal pictures.
Autofocus, as the name suggests, is nothing but the system that automatically adjusts camera focus. It is usually recommended to use the autofocus setting as it prevents producing out of focus images, but a manual focus setting is also given so that photographers can adjust the focus themselves. Camera phones or other cameras, except DSLRs, have the autofocus system embedded to produce optimal images.
A flash unit is nothing but the emission of light which enhances the light factor while taking pictures. While every camera has a built-in flash unit, not every flash unit is as useful as the one which the DSLRs have. Using a flash usually mimics a natural light when there’s low light and helps in capturing perfect pictures. The flash in camera phones work only till a certain distance because the flash unit embedded has a small flash. There’s always a drastic change in imagery with and without flash. DSLRs have certain flash modes which help in determining the kind of flash one needs.
Pixels are small squares like pieces of a puzzle that are put together to make up a photograph. A megapixel is 1 million pixels. The resolution of any camera is determined by how many of these squares are crammed in a single picture. The more the pixels, the better clarity you have with photographs. The number of megapixels simply determine how much information is provided in a single picture. The more the pixels, the better. The intensity of a pixel also depends on how large a print you want if you are a professional photographer. It also depends on how well you use your camera.
Cameras usually either have convenience or weatherproofing. With point and shoot and phone camera, you will get the convenience but not the full-fledged weatherproofing. Whereas with DSLR and the action camera, you will get the weatherproofing as they are used by professionals on a large scale. Any camera is designed to be durable as it must perform in any condition and can offer excellent picture production.
Zoom means the ability to make something distant appear closer. Consumer cameras are sold with a maximum zoom which is supposed to define how much closer your object is. For example, a camera might be 40x zoom, 4x optical, 10x digital. The zoom factor of a camera depends upon the camera that you’re using. If you have a point-and-shoot camera, the zoom is built-in and gives you optimal zooming capability. Whereas in DSLR, the zooming depends upon the lens’ capacity to magnify. But when the aperture is maximum, there is a loss in image quality as it gets distorted due to the maximum zoom.
Inside your camera, straight in front of the sensor, is a small flap called the Shutter. When you take a photo, this opens and closes to let light reach the sensor, creating your image. Shutter speed defines how quickly or slowly the shutter opens and closes again. The speed of the shutter determines the quality of your photo and how much exposure you want while clicking it.
A viewfinder is what the photographer looks through to compose, and, in many cases, to focus the picture. Viewfinders can be optical or electronic. An optical viewfinder is just a reversed telescope mounted to see what the camera will see. The drawbacks are many, but it also has advantages. It consumes no power, it does not wash out in sunlight, and it has 'full resolution'. An electronic viewfinder (EVF) is a CRT, LCD or OLED based display device, though only the LCD is commonplace today due to size and weight.
GENERAL FEATURES OF A CAMERA:
While most of the cameras have the Wi-fi capability, some DSLRs have just started getting the Wi-fi option for sharing the photos instantly. While action cameras, point and shoot and phone cameras have Wi-fi option, most DSLRs still do not have that capability. They have far too many large files that need a lot more to save and share with other devices. Bluetooth, on the other hand, is less popular with DSLRs as the large files need a faster medium than Bluetooth. Make sure you have all the needed specifications like the sharing option. If you like to post on social media as soon as you click, you might have to buy the DSLR or an action camera with a Wi-fi facility.
Storage usually depends on what type of camera you have. As different cameras have different file sizes, you will have to look for a storage option that is convenient for you. DSLRs store the photographs in large file sizes as their photo quality is higher. Memory cards in all the cameras are a must as they offer the flexibility of transferring the pictures much quickly. While buying a camera, make sure you get storage to the maximum capacity so that you won’t have to transfer the pictures frequently and can click them without any storage hindrance.
GPS (Global Positioning System):
The latest feature that the cameras have nowadays is the Global Positioning System. So, the next time you click a photo, you’ll know exactly where you clicked it. A built-in GPS unit with a camera can help with the location tag issue. A GPS unit can add EXIF data to your photo files, allowing you to identify the exact location at which you're shooting your images. Although some cameras can use external GPS units, having a GPS unit built into your camera makes things easier.
While clicking pictures from a camera phone, we usually click in portrait mode as it covers a specific portion of the scene and does not occupy every angle of the view that is to be pictured. Portrait pictures are taller than they are wide giving you a precise click of the scenery. You should always know when to click a portrait as it is very subject-oriented.
Landscape is a format that captures all the scenery and gives you the whole imagery of what you want to capture. Landscape is wider than it is taller. Landscape includes more of the foreground and has all the necessary elements that completes a landscape format. Landscape is not at all subject-oriented as it covers almost all the angles and gives you a bigger view of the scenery.
Every camera that has an option to click pictures will have the video recording option also. A video recording mainly consists of recording small videos because there are special recording cameras that capture videos with more superiority. Phone cameras or the point and shoot cameras have lesser video recording capability than the DSLR and Action camera. DSLRs can also record HD videos which often have a very large size.
A camera lens is an optical lens or several lenses used in combination with a camera body and mechanism to make images of objects either on photographic film or on other media that can store an image chemically or electronically.
Factors to consider before buying a lens:
Different lenses have different perspectives. When you have a Macro lens, you are only subject driven as it is capable of only capturing close-ups and a specific frame. A macro lens may be of any focal length, the actual focus length being analyzed by its practical use, considering magnification, the required ratio, access to the subject, and illumination considerations. Whereas when you get a Zoom lens, it may zoom from moderate wide-angle, through normal, to moderate telephoto; or from normal to extreme telephoto. Besides DSLRs, lenses are fixed in other types as they do not need much details when capturing pictures or videos. Phone cameras have small lenses but of a superior quality.
· Maximum Aperture:
Having a lens with minimum aperture makes you adjust the ISO sensitivity to another level. Instead of compromising on so much ISO adjustments, try buying a lens with maximum aperture and get the best outcome with optimal brightness. The larger the aperture, the less flash you get to use. While pictures using flash are good, but pictures taken in a natural light are more vibrant. Consider buying a basic lens and a lens with maximum aperture to get optimal results. Reasonable affordable examples are a 50mm f/1.8 and a 30mm f/2.0.
· Size and Weight:
While getting a lens with maximum aperture is good, it also affects the size and weight of the lens which is a crucial factor considering you have to carry all the accessories everywhere. The DSLR owners are mainly affected by this as other camera types have fixed apertures or very small considering their lens sizes. Buy a lens which fits all your basic needs as that is going to unburden you from all the unnecessary weight you have to carry while going on vacations or photography trips.
Image Stabilization is an issue that everyone faces at one point or another. It distorts your image and disrupts the autofocus by which your image begins to blur or distort at some angles. Some have the stabilization feature in the lens or in the camera itself. Image stabilization is an issue that relay makes the photographers suffer as a moment missed during a session can cost you a really beautiful photograph.
Ideal Users Of Different Types Of Cameras:
Different types of photography requires different types of cameras, here we will give you clarity of types of photography requiring different types of cameras:
Wildlife photography is a genre of photography concerned with documenting various forms of wildlife in their natural habitat. The high-definition pictures that we see of wild animals in their own element are clicked by professional wildlife photographers. It is considered as one of the most challenging forms of photography. Wildlife photography needs the photographer to be agile and he needs to adapt to the weather conditions and the various surroundings he’s in. There are weather-proof cameras that can sustain through extremely cold or hot weather. There is also a host of rugged compact cameras that all support use in freezing conditions (up to 10 degrees Celsius) as well as offer waterproof and shockproof benefits. Companies like Canon, Fujifilm, Nikon, Olympus, Panasonic, Pentax and Ricoh manufacture these durable cameras.
A candid photograph is a photograph captured without creating a posed appearance. The subject should be in motion and in his own actions to get a proper candid photograph. Unobtrusive camera equipment, often small in size, is favored for candid photography to avoid disturbing subjects. Black-painted cameras have long been preferred. Candid photography also typically needs use of available light since flash // alerts subjects to the camera and may surprise them, causing them to react or become self-conscious and stage their photo appearance rather than behaving naturally.
Landscape photographs naturally capture the existence of nature but can also focus on man-made features or disturbances of landscapes. You can use ordinary camera; film camera or digital camera can be readily used for common landscape photography. Higher-resolution and larger-format digital cameras allow a greater amount of detail and a wider range of artistic demonstration. A camera with 'panorama' function or frame can capture very wide images suitable for capturing a panoramic view.
Adventure photography is just the act of photographing adventures, typically in the outdoors. It's a forte defined by stunning landscapes, dynamic personalities, and challenging, ever-changing shooting conditions. You can use DSLR, Mirrorless or Action cameras for this type of photography as they provide with the best images without wasting that crucial moment. The lenses that can be used are zoom and prime as they both allow you to have the freedom to capture any moment.
