photography
can someone explain the aperture and shutter speed to me? i guess the bigger the aperture the smaller the amount of objects that can fit in the photograph? and the shutter speed higher you can take a pic of a moving car??? but what do i use in bright light, low light, and inside a building??? for posed objects

Hi
Aperture = size of the hole which is exposed when the shutter is triggered. As the F-stop/Aperture number increases, the aperture opening gets smaller. (F3.8 is a bigger hole than F8)
Shutter speed = the speed at which the shutter flips.
The larger the aperture, the less "depth of field" you get, but you also let more light in.
Depth of field is the number of feet or metres that the focus covers
Say you focus on a vase - there is a bucket behind the vase, and a coin on the table in-front of it. If you depth of field is small [high aperture], then the bucket and coin will be blurry, and the vase sharp. If your depth of field is bigger, not only the vase, but the bucket and coin will also be sharp.
So a larger aperture = less you can capture clearly, but you can capture it faster, because you are letting more light in quickly.
As you increase your aperture speed, because you're letting more light in, you can increase your shutter speed (which will decrease the amount of time the light hits the film/digital sensor.
An increase in shutter speed lets you catch fast-moving objects, like moving cars, while limiting the time they're being captured, which means less blur, because less time = less motion.
If you're taking photos of things inside, and they're still, you don't need a really fast shutter speed. The only advantage of shutter speed is to catch things without moving the camera.
If you have a tripod, and none of the things you are photographing move, set the shutter speed as slow as possible, and the aperture as small as possible (High F-number). It will give you a sharper, less grainy photo.
If you want an effect where things in the foreground and background fade into blurriness, set the aperture larger (smaller F-number), and the shutter speed higher (to compensate for the large aperture).

the higher the aperature the less light coming into the camera its like a fraction f16 is smaller than f8 therefore f8 lets in more light.... the bigger the number of the shutter speed the faster it is so 265 is not as fast as 1000 it with the car if you want the whole pic to focused you need to use a high shutter speed . but if you want to do what they call panning have the car in focus and the background blurry you need to use a slower shutter speed and follow the car there should be a light meter on the camera inside the viewfinder either on the left or right hand side.. look in there and try to get the line in the middle or get a green dot .. this means you have the correct exposure... hope i helped. if you ahve anymore questions ask me :)
