while i appreciate the link, it's far to technical... damn that makes my eyes hurt! i don't understand a thing :(

Well photography isnt easy.   I took a basics class in college just for fun and it was a little confusing at times.   But it was still great.  My best advice to you is take a car around a track a few times and enter photo mode and then just play around with the settings a bit.  Start off small with just changing the shutter speed, just so you can see with your eyes what it will do,  then move on to the other settings.

so.. if i'm in photo mode, how do i get the car to look like its moving? i want motion blur for example?


es,  so you would leave the shutter speed to a lower level,  like 1/250 or 1/500,  if you want to remove it,  1/2000 or higher


but when i tried it on the photo mode, the higher setting or the lower setting didn't change anything.

Was the vehicle in motion or was it a still shot?

a still shot.

Here,  it s Ferrari Enzo doing 200mph on High Speed Ring, all I did was change the shutter speed, its the same picture otherwise

1/250

1/500

1/2000

1/8000

Shutter speed has a smaller effect on still items then moving ones.

Aperture is how much light you let hit the iris of the camera.   Think of it like your pupil in your eye.  The larger the your pupil the more light will be let in, same with the Aperture setting.  But since its a ratio the numbers are flipped, the bigger the number the smaller amount of light that is let in to the iris.  An aperture of 1 is considered a wide open lens, and all light from the shot will hit the iris of the camera.   If a picture is to bright,  you will need to raise the aperture setting to let in less light so its not too bright.  And vice versa if the picture is too dark

Depth of field is relative to the object you are focusing on.  A short depth of field means that there will be little distance in front of and behind the object that is in focus.  A long depth of field means that there will great distance in front and behind the focus point that will be in focus.

 

The left side has a short depth of field while the right side has a long depth of field.  A short depth of field is good for shooting portraits of people when you want the viewer of the photograph to direct his attention to the person rather than the background.  A long depth of field is better when photographing landscape or cityscape when you want everything in the background to be in focus.

 

A smaller aperture number will result in a shorter depth of field and a larger aperture number will result in a longer depth of field.



"Naturally the common people don't want war: Neither in Russia, nor in England, nor for that matter in Germany. That is understood. But, after all, IT IS THE LEADERS of the country who determine the policy and it is always a simple matter to drag the people along, whether it is a democracy, or a fascist dictatorship, or a parliament, or a communist dictatorship. Voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is TELL THEM THEY ARE BEING ATTACKED, and denounce the peacemakers for lack of patriotism and exposing the country to danger. IT WORKS THE SAME IN ANY COUNTRY."  --Hermann Goering, leading Nazi party member, at the Nuremberg War Crime Trials
