Using a slow shutter speed allows for a lot of motion to be recorded in a picture. In this picture, you can see the complete travel of stars overnight. Taking a picture like this can be very tough, you must keep a camera nearly perfectly still for an entire night. To make sure that the image isn't over-exposed, you have to use an extremely small aperture size. With this aperture, you also get a very large depth of field, capturing detail of the entire picture.

Using a fast shutter speed is great for getting a really solid detail and little to no blur in an image. If the subject is moving quickly, the photo seems to literally freeze time. In reality, the cheetah and prey in the picture above are probably moving quite fast, however, we do not get to see this. When using a fast shutter speed, you have to compensate for lighting by using a larger aperture size and changing the ISO speed. When using a large aperture, the image tends to have a shallow depth of field. The problem with increasing the ISO is that it can make the image much granier.

Henry Cartier-Bresson says that a photograph must be taken during the "climax" of the scene. There is a decisive moment which shows the subject's emotion best, and everything falls into place. This image was taken just as Cartier-Bresson walked into the room unexpectedly. The people each have unique, one-of-a-kind expressions showing them just seeing somebody walk into their home. If he had taken the photograph seconds later, the subjects would have probably had completely different expressions, much less human than the ones they have in the photo. The expressions shown are true.
