Cameras

Recently one day my friend asked me to suggest a good cam as he was going to buy one. Then I realized that I knew nothing about cameras. My knowledge in that area was pretty weak. I never came across a situation where I though about buying a camera. My first and only camera is the Canon sx130 that my brother gave me. It is a pretty good cam with almost all the options that a DSLR has.

All I knew was there are two types of cameras one the good looking, heavy and costly DSLRs for which you need a separate bag to carry them and the others were non DSLRs which are small, pocket sized and cheap. I think every one who has a little interest in photography will have this basic knowledge. To get to know more about the different types of camera I consulted the knowledge guru, the big daddy Google. Here is the some of the information that I have got from it.

Basically we can categorize cameras as digital and non digital. I don't think no one now a days use a non-digital cameras. For those who do not know the non-digital cameras are the prehistoric cameras which used to have a photo films in it and the photos were developed from these films in a dark room using some chemicals (No offense intended). Let us look at the different kinds of digital cameras that are available.

Again the digital cameras can be categorized into two types. The point-and-shoot and the SLR. To those who don't know in DSLR, SLR stands for Single Lens Reflection and D for digital. The point-to-shoot cameras in shot P&S cams and the DSLRs differ in the range of options they provide to the photographer.

Point and shoot cameras mean just that, point the camera at something and trip the shutter. The camera does all the work for you. Unfortunately, the camera is rarely as smart as the photographer so the results may not be as good as you want.

Features
  • Metering systems, which calculate the amount of light entering the camera
  • Variable shutter speed
  • Variable aperture
  • Zoom lenses
  • Automatic focus
  • Preset controls for various photographic situations such as:
    • landscapes
    • nighttime
    • people
    • close-up or macro
The biggest drawback to P&S cameras is that many do not have a through the lens (TTL) viewfinder. This means that what you see through your viewfinder may not be what you capture on film or digital media. P&S cameras are usually small and fit into a pocket or purse. They are best used for casual picture taking where capturing the memory is more important than creating a marketable image.

SLR and DSLR

Description
SLR stands for Single Lens Reflex and DSLR stands for Digital Single Lens Reflex and refers to how the light enters the camera. These are the cameras you see many professionals and serious amateurs carrying around. These cameras have a larger body than most P&S cameras and interchangeable lenses. While SLRs started out a fully manual, where the photographer had to control all features including focus, most of these cameras are capable of acting in a fully automatic mode just like a P&S. Many now allow the photographer the freedom to also take control of all functions or any combination of functions. These cameras allow for great control over the photography process and allow the photographer to take images not always possible with a P&S.

Features
SLRs and DSLRs allow for control over:
  • shutter speed
  • aperture
  • film speed
  • focus point
  • magnification (through the use of various lenses)
  • capability for add-on flashes
  • remote releases
  • additional battery packs
