Don't skip the basics. If you skip the basics you will find it hard to understand the more advanced techniques. Once you understand the basics that understanding will help you quickly master the advanced techniques.
What is the basics in photography? It's how to get correct exposure on your pictures.
Wokeh! Time to get into explanation mode again...
For all the beginners out there. I know you are excited in getting brand spanking new DSLR/DSLT but you need to get one thing right first : how to get correct exposure on your pic before you leave 'AUTO' or P mode. Jumping straight to M mode is bound to be really frustrating if you don't understand the basics.
Exposure on your pic depends on 3 settings on your cam. In fact it's the same in EVERY cam. Just that some cameras don't let you fiddle with some of the settings.
The 3 settings are : Aperture, shutter speed and ISO.
What is Aperture?
It's the opening in your lens that control how much light can go through. You can control aperture by making the opening larger or smaller. It's denoted by the f number on your cam. E.g. f 2.8 / f5.6 /f8 etc.
Now one thing you need to understand is the bigger the f number value, the smaller the opening. Meaning at f11 your aperture opening is smaller compared to f4. So if you want to let more light through you need to set your f number to a smaller value. Confusing? Yes, it is.
To avoid confusion it's better to refer to aperture using 'bright' or 'dark' rather than large or small. Thus f 2.8 is a bright aperture and f8 is a dark aperture.
What is shutter speed?
It's the duration of time that the camera exposes the sensor to light. The longer the duration, the more light can reach the sensor.
What is ISO?
It's the sensitivity level of your sensor towards light. The more sensitive it is, the easier it is to capture the image.
How the 3 works together to determine your exposure:
First thing is aperture value. Depending on your lens, the range of aperture you can use is limited. E.g. your kit lens only allows the brightest aperture at f 3.5 thus let's use this as an example.
You set your aperture to f 3.5
Next your shutter speed. How long do you want to expose the sensor to light? 1/10th of a second or 1/100th of a second? Let's take 1/100th of a second as your second setting.
Lastly your ISO. Let's say you set it to ISO 200.
So you take a shot a f 3.5, shutter speed 1/100th of a second at ISO 200.
If the picture comes out dark. What do you do?
First let's explore aperture. It's at f 3.5 and your lens cannot allow any other brighter setting so you're stuck with that.
Next shutter speed. At 1/100th of a second the picture is dark. To make it brighter, what do you need to do? Extend the duration the sensor is exposed to light, right? So adjust your shutter speed to 1/60th of a second.
You take another shot at f 3.5, shutter speed 1/60th of a second at ISO 200.
The picture now is brighter but still not bright enough. So you adjust the shutter speed to 1/30th of a second and take another shot.
At f 3.5, 1/30th of a second, ISO 200 the shot is bright and just right but you see that people that are walking in your pic appears blurred due to movement. This is because your shutter speed is too slow to freeze movement. If you want to freeze the movement then you need a faster shutter speed. So up it goes back to 1/60th of a second.
But at 1/60th of a second the picture is not bright enough. What else can you do?
Let's check out ISO.
From 200 you increase it to 400 and take another shot.
At f 3.5, 1/60th of a second, ISO 400 the picture comes out just right because your sensor is now more sensitive to light.
And that's how aperture, shutter speed and ISO work together to get you your exposure level. Understand the relationship between the 3 settings will get you a long way towards getting the picture you want.
I hav read other ppl blog about this oso....trying to ply wif those three setting lo...
well done, william..my sifu..
sometimes theory and practical is big differences...even if you know alot about theory, does not mean u can shoot well....same to if you langsung dono theory, through practices u may excel those who pro theory....can understand well all the basics and able to apply to the photo as well as able to make a nice framing angle is a different thing..
as the saying goes: learn from experience...experience will teach u more..try try try..never give up..

ok, understand, i will nvr give up and try...nw i everyday ply wif cam, my eyes is so painful nw...lol
