Hello again to all of you..
I want here to share some of my knowledge: The Basic of Photography. I'll try to explain it as clearly as possible. Hope that it will be useful for you ^^
Today is digital era. Digital cameras are now being more produced than analogue cameras. With its easiness and low cost in developing, many people buy digital cameras.
Compact cameras are the most commenly camera, used by traveler. It is full automatic, just press the shutter and you have the picture.
Well, if you want to learn a bit photography, it is better to use a camera that is not full automatic (at least there are P, A(or Av), S(or Tv), M shooting mode).

Well, if you want to learn a bit photography, it is better to use a camera that is not full automatic (at least there are P, A(or Av), S(or Tv), M shooting mode).
- A or Av is the Aperture priority mode, here you could set the Aperture. (The use of Aperture and Shutter Speed I will explain soon)
- S or Tv is the Shutter Speed priority mode.
- In the Manual mode (M), you can adjust both Aperture and Shutter Speed.
So, these are the basic: Aperture, Shutter Speed, and also ISO (also known as ASA). I will also give the explanation the Relation these three elements.
Aperture: The Use and Effect
The Aperture or blend opening has the same use as pupil in our eyes. The bigger the opening, the more light you will get.
In frontside of the lenses, there are many numbers, e.g f/2.8-f/3.2. This number refer the blend opening.
Small number means big opening (example: f/2,8 or smaller number) and big number means small opening (example: f/8 or bigger number).
The big opening gives you more light and vice virsa. It will be very useful to have a lens with big opening especially in low light situation.
I think it is clear enough for you.
Next, the effect of this element..
Aperture is not just about the "light income" but also Depth of Field (DOF). Wait a minute... DOF? What's that?
Deep of Field determine the sharp area in a photo. The sharp area is in front and back of the focus area. For example:
A Sign?

Shutter Speed: The Use and Effect
Shutter speed determines how long is the light exposure. 100 doesn't mean 100 seconds, but 1/100 second and 3" means 3 seconds. Logically, the longer the exposure, the more light the sensor will recieve.
If we want to shoot an object that moving pretty fast (and want to "freeze" it), use the high shutter speed, e.g: 1/200 second. Using the low shutter speed makes the moving object blurry.
The long exposure time normally used to take picture at night or low light condition. It can also used for other situation, like the flowing water effect.
Another great effect: If you shoot streets where many cars go through at night, you'll get lines of light. It's great ^_^
If you want to use the low shutter speed (especially if you want to shoot buildings or steady objects), use a tripod or put the camera on something that is stable. Use also the timer to prevent shacking that is caused by your hand.
These are some photos, which I took with low shutter speed:
A Flying Card
Red, Yellow, Green

ISO/ASA: The Use and Effect
Okay, here we come to the last element from the basic of Photography: ISO/ASA. ISO usually used for the films (analogue cameras), and today we use sensors in digital cameras. This term "ISO" is today also used in digital photography.
In digital photography, ISO determine the light sensitivity of the sensor.
High ISO speed (e.g: 400 or 800) gives you more posibility taking photos in low-light condition, because the light sensor is more sensitive than in low ISO speed (e.g: 100)
In digital camera, the ISO speed can be set manually and automatically.
The bad thing if you use high ISO speed, you will see many unexpected coloured dots (it's called "noise"). I don't really know how it comes, but I think it is like miscalculation from the sensor.
It also depend on the size of the camera sensor. The smaller the sensor, the more noise will appear. That's why if you take pictures with dSLR (with high ISO speed), the pictures seemed to be less noisy than if you use a digital pocket camera.
I usually use the low ISO speed (normally 100 or 200), because I want to prevent the noise. In some situation I use ISO 400 or 800.
But it is your decision, if you want to use high or low ISO speed.
Here are two pictures, which were shot with different ISO speed:
@ISO 800
@ISO 200
crop 100% @ISO 800
Click the picture to the see it clearly (1.2 MB).
crop 100% @ISO 200
Click the picture to the see it clearly (1.2 MB).
In digital photography, ISO determine the light sensitivity of the sensor.
High ISO speed (e.g: 400 or 800) gives you more posibility taking photos in low-light condition, because the light sensor is more sensitive than in low ISO speed (e.g: 100)
In digital camera, the ISO speed can be set manually and automatically.

Relation
Taking pictures with ideal mount of light are like filling a glass with faucet. How much volume in second determine the Aperture and how long you need to fill the glass until it is full determine the shutter speed.
If there is too little a mount of water, it means the picture is too dark ("underexposed"). If there is too much water, it means "overexposed".
The relation between the Shutter Speed and Aperture is very important.
If you use a big Aperture (e.g. f/2.8), you'll need to use a high shutter speed (e.g. 1/100 second, but it depands on the available light). If you need a smaller opening, use slower shutter speed.
You can also adjust the sensitivity of the sensor (ISO). Using high speed ISO (such as 800 or 1600), gives you more chances to shoot in low light condition. You can shoot with higher shutter speed or smaller Aperture.
But once again, using high speed ISO decrease the picture quality.
Well, I think that's all about the basic of photography. I hope it is useful for you ^^
