Photography has seen a revolution with introduction of digital cameras. Working on the same principle of optics, digital cameras can do everything that film cameras did in addition to a whole bunch of things which were impossible before. Now you can instantly shoot and preview a picture, delete it if you don't like and edit it with built in basic image editor.
Digital photography is fun and now almost every one has a digital camera in his or her pocket as almost every mobile phone has a integrated camera. Let's explore further and see what kind of cameras we have.
Digital cameras can be roughly categorized in two types:
- Compact or Point and Shoot Cameras
- Interchangeable Lens Cameras
Compact cameras or better know as Point and Shoot Cameras are suitable for causal use. They are light, compact and easy to use. They have a small image sensor, fixed lens, integrated flash and LCD screen which acts like the view finder and to preview taken pictures. They have high depth of field and use contrast detection based auto focus. Using a point and shoot camera is as simple as it's name though some of the models have incorporated various functions and modes.
There is another sub category in compact cameras that is knows are Bridge Camera which are basically high end Point and Shoot Cameras which resemble DSLR by looks and provide a host of features and greater control on the camera optics. Most of the bridge cameras offer manual focus, long zoom range and ability to control aperture and shutter speed. However, they still use small image sensors and lack the ability to change lens.
Advantages Of ILC:
- Size and Weight
- Quiet Operation
- Auto Mode
- Price
Disadvantages:
- Image Quality
- Smaller ISO range
- Speed
- Reliance upon LCD
- Limited Manual Controls
- Less Adaptable
Interchangeable Lens Cameras can further be classified in to
DSLR (Digital Single Lens Reflex) and MILC (Mirrorless Interchangeable Lens Camera). Biggest advantage of these cameras is their ability to change lens and use external flash. DSLR camera uses mechanical mirror system or pentaprism to direct light from the lens to optical viewfinder. Therefore, you shoot what you see because because of an accurate preview of frame close to the moment of exposure. They use a larger APS or full frame (35mm) sensors which results in lower noise, higher sensitivity, and increased latitude and dynamic range. DSLR cameras are offer full control over the camera optics and one can change shutter speed to expose the subject to as long as hours. A number of lenses with variable or fixed focal lengths allow you to shoot at macro mode, zoom , closeup and wide angle. Control over aperture allows to change the depth of field and give a blurring effect to the background. DSLR cameras are bigger, heavier and expensive than compact camera's and are preferred by professional photographers or photography enthusiasts.
combine many of the benefits of both compact cameras and DSLRs. Compared to compact cameras, they offer a larger sensor and hence higher image quality, and generally include more features and controls. They have DSLR like body and ability to change lens but do not have a mirror or pentaprism optical view finder. Instead they have a electronic view finder which makes them significantly thinner, lighter and cheaper than DSLR. They are suited for amature or serious photographers.
Advantages:
- Image Quality
- Adaptability
- Speed
- large ISO range
- Manual Controls
- Quality Optics
Disadvantages:
- Price
- Size and Weight
- Maintenance
- Noisy
- Complexity
Choosing a Camera for you: Both compact and DSLR cameras have their own advantages and disadvantages, so you should be asking yourself what exactly you need and then choose according to it. If you like taking casual pictures but do not like a camera that is complex and expensive then I would suggest a mid level compact or a hybrid camera. However, if you are serious towards photography and want to dig deeper in the world of photography then a DSLR is highly recommended.
