Introduction

Welcome to my blog, glad to have you reading my first entry. Generally I will talk about photography and camera, and things related to them. 

I would like to advise that before you buy camera, or if you want to make photography as your new hobby, make sure you know a little bit photography and the camera itself. 

Nowadays, when we talk about photography, people will automatically think about the DSLR  (digital single-lens reflex). They are  digital cameras that use a mechanical mirror system and pentaprism to direct light from the lens to an optical viewfinder on the back of the camera (Wikipedia).

DSLR 













Compact Camera























There are quite clear differences between these two types of camera. 
  1. Viewfinder Mechanism - Unlike compact camera, with DSLR camera, what you see through the viewfinder is the same light that will reach your camera's sensor. With compact camera, the viewfinder mechanism just tries to estimate what light will reach the sensor, thus making it less accurate compared to DSLR camera.
  2. Interchangeable Lens - Of course you want to change your lens depending on situation. For example, taking photos of birds or wild animal, you will need a zoom-lens. But when you want to take some scenery, usually you will use wide-lens. 
  3. Camera Sensor Size - In general, compact cameras have much smaller sensors than DSLR cameras. This is a less commonly known difference between the, but is likely one that will make the most noticeable impact on image quality.

SLR Camera Advantages
Faster camera auto-focus.
Much less shutter lag (delay between pressing the shutter and starting the exposure).
Higher maximum frame rate.
RAW file format support (although most high-end compact cameras have this).
Ability to take exposures longer than 15-30 seconds (using manual or bulb mode).
Offers complete manual exposure control.
Ability to use an external flash unit (but many high-end compact cameras have this).
Manual zoom control (by twisting the lens as opposed to using an electronic button).
Greater range of ISO speed settings.

Example of long exposure. (about 20-30 seconds)
  
Example of photo taken using macro lens.

So that is why photographers prefer DSLR cameras instead of compact camera. Let me remind you again, you will need some practices and skills to get best results. It is not easy to master, but it is also not hard to learn it, anyway.

As I mentioned earlier, it is advised to know a little bit about the art of photography, and how to make full use of camera before you buy it, because it is not cheap$$$$. I will talk about basics of using cameras and tips on buying them, in the next entry.
