Let's assume this is a film SLR with a dual curtain shutter since you didn't specify digital or not. When the shutter button is depressed, three things happen virtually at once. 1) the reflex mirror flips up to get out of the way of the light transmission. In so doing, it covers the focusing screen. 2) the lens "stops down" to the aperture chosen for the exposure by moving a series of metal blades (if it is to be less than fully open). 3) If the exposure time is equal to or longer than the flash synchronization speed, one curtain moves (usually horizontally), which uncovers the film opening for the set time. This curtain closes the flash circuit contacts and the flash fires while the film is completely uncovered if a flash is being used. Light transmits (not reflects) through the lens assembly to reach the film. The second shutter curtain closes, the mirror drops down and the aperture opens up again.
If the shutter speed used is faster than the flash synchronization speed, the second curtain begins closing before the first has finished traveling. This has the effect of passing a slit across the film. The faster the shutter speed, the smaller the slit, so this design is capable of producing effective shutter speeds of 1/4000th of a second or less. When the shutter is cocked, the film advances and the shutter curtains travel back to their ready position. Some cameras use a vertical traveling metal shutter made up of a series of blades. They typically do not have a following curtain, and the distance of travel is 33% less than a horizontal moving shutter. This means their fastest shutter speed usually exceeds 1/1000th of a second.
This is how the film is exposed to the light focused by the lens.
Micron
An exposure is made when light passes through the camera lens and hits the camera sensor or film. The amount of light that reaches the sensor or film is controlled by the aperture size, shutter speed, and ISO setting, which determine how bright or dark the final image will be. The combination of these settings determines the overall exposure of the image.

What are the characteristics of correct exposure over exposure and under exposure?
A "correct" exposure is one that gives you a photo with the tones and densities your artistic vision calls for. An "overexposed" picture is too light, and an underexposed one is too dark. The problem is, what are you trying to achieve with your picture? Maybe I'm taking a picture of a covered bridge where you can see the entrance. If I want the most detail in the outside of the bridge, the inside will plug up because there won't be enough exposure. If the inside is more important, the outside is going to get very light. And if the important thing to me is the river under the bridge, which is very light, then the bridge itself is going to look very dark.
What is an example of a sentence using the word exposure?

What are the effects of aperture in a picture?
Possible over and or under-exposure. But basically, in English, it effects the brightness/exposure of your image.
What is auto exposure?
Well.. Exposure is how long the camera takes to take a picture. A long exposure time gets a better and higher quality image when the camera is still. A short exposure is when the camera may move or something in the picture may move. So to keep it from blurring the camera captures an image for a fraction of a second. Auto exposure does this automatically analysing whats happening in the picture to create the best of both worlds basically.
How to move the car while taking picture?
