Lenses and Photography Vocab.

I would use a telephoto lens to take a picture at a concert.

I would use a prime lens to take a picture of a unique looking flower.

I would use a wide-angle lens to take a picture of a landscape.

Depth of Field- pertains to the range of distance that appears acceptably sharp. You can use depth of field to take better photos by blurring out your background.

Light- a source that brings the picture to life depending on where it comes from and how much there is of it. You can use light to make your photos better by having the correct amount of exposure.

Shadows- can be effectively used to focus a viewer's attention. You can use shadows to improve your photos by covering what is unneeded or distracting in a picture.

Diffusion- the action of spreading light, as to reduce harsh shadows or soften the look of artificial light. You can use diffusion to make your photos better by covering up the flash with a thin sheet of paper.

Exposure- the measured amount of light allowed on each section of a photo. You can make your photos better by making sure the amount of light let in or exposure is right.

Aperture- the size of the hole on a camera in which a certain amount of light is let in. You can improve your pictures by changing the aperture in different lighting situations.

Shutter speed- is the speed in which the aperture is allowed to open and then close. You can take better pictures by changing your shutter speed according to if an object is in motion.

ISO- is the sensitivity to light. Your pictures will be better if you keep the ISO low, otherwise photos will be grainy.
