i know that the aperture value is the amount of light that can pass through the lens. the larger the value, the smaller the amount of light can pass through.. (am i on the right track????)
the iso value is the camera's sensitivity to light.
so what is the relationship between these 2? i quote from canon's website.. "Changing the aperture affects the depth of field, while changing the shutter speed affects the freezing or blurring of motion." and i don't understand what does that mean... is there any additional knowledge that i need?

hi bro...im  beginner...

i have problem taking moved picture???is it setting or the shutter speed...normally in the dark light...
