DEPTH OF FIELD PICTURES

Here's a picture of the pink dinosaur and the t-rex out of focus and Steggy in focus:


This is a picture where just where the pink dinosaur is in focus:


Here all of them are in focus:

DEPTH OF FIELD

The depth of field is the distance around the focal plane which is very focused. Or when you see a picture such as the one below where one subject is focused, but the aren't as focused. Two things that affect the depth of field are the aperture and the focusing distance. When you have less aperture you can see farther or in other words it won't be so blurry. The focusing distance is using your zoom on some cameras or on other just adjusting the lenses.

TYPES OF PHOTOS

Blurred Action: This is when the photo is taken with a slow shutter speed. This doesn't mean the whole photo needs to be blurry it can just be the background or something. Also for a great blurry picture you can adjust the exposer time.


Stopped Action: This is when the shutter speed is very fast but still the picture is very clear. It is almost like a normal photo unless you somehow make it blurry. An example of this would be the picture of the tennis player about to hit the ball.


Panning: Panning is the effect which the camera or the video camera is moved horizontally or just scanning the subject. People who are most likely to use this is a photographer or someone filming a movie or just in general. You can set the shutter to different speeds to capture different effects such as slowing it way down (1/15 or slower) and freezing the picture.

EXPOSURE

Exposure is the amount of time is it takes the for the light to come in. Pictures can be over exposed or underexposed. Which means some tend to be darker and some tend to have too much light. Along with just over exposer or under exposer there is also the shutter speed and then aperture. The shutter speed is the speed in which it shuts, it is measured in fractions of seconds. The aperture the lens taking in the light and for a certain time, aperture is measured in f/stops. f/stops are on scale from f/1.4 to f/22. to calculate the f/stops you must use the formula, see below. Shutter speed and aperture relate because the shutter is when or how much light is expose to the sensor. Shutter is measured in 1/2000. Aperture is measured in f/stops and is how much light is let into the camera. Some camera settings that let you use aperture and shutter speed is manual. Metering is when you have automatic exposer.

Heres's an example:


Here is the formula:

TIRE

This is a picture of a tire in my backyard. It was placed there to hold down the tarp that you can see in the background.
