Part 5 - Exposure

To find out the right exposure for taking a picture, it is necessary to know about the affection of the exposure time of a camera.

Basically it is up to the aparture opening, where the light is captured onto the film or to the light-sensitive sensor (digital Camera).

The longer the aparture is open, the more light can be captured and the picture will be more exposed. When it is very dark outside and there isn`t enough light, you are in need of a long exposure time to get an appropriated picture.

It can happen that pictures are out of focus, when using a long exposure time, because objects you want to take a photo of are more likely to move in that time. That is why there are different programms to help you to use the exposure time.

Part 6 - Exposure Time

As mentioned above it is possible to expose a picture for a long time or even just for a few miliseconds.

The short exposure time is often used when it comes to sport photography, where the objects are usually in move. To be able to get a pin sharp photo, the time, that allows you to capture the incoming light, has to be as short as possible so that in the meanwhile the object can`t move that much.

Taking night shots compared to sport photography you use the exposure time to get as much light as you can to counter bad light situations. As you can imagine, here it is recommanded to choose a long exposure time.
