Photography

Question 1

What is a Drive dial?

Answer 1

Drive dial over on the left side of the camera controls what happens when you press down on the shutter release

Question 2

What is aperture?

Answer 2

The aperture is the opening within the lens that limits the amount of light that can pass through it.

By changing the aperture value, you increase or decrease the size of that opening, thereby allowing more or less light into the camera.

Aperture is measured in f-stops, such as f/16 and f/14, but here’s the thing: The smaller the f-stop number, the larger the opening, and vice versa.

If you want less light to enter (small aperture), go for a larger f-stop. How large your lens’ aperture can open will depend on your lens. (Hint: A lens’ maximum aperture will be part of its model name, like a 50mm f/1.8 or a 24-120mm f/4.)

Question 3

DOF

Answer 3

Depth of field. How much depth will be in focus within the image.

An image with a large DOF will have sharp focus from foreground to background, while a small, or shallow, DOF sees the focus concentrated on one particular plane, with foreground and background elements blurred away.

When thinking about the f-stop, choose a smaller number (larger aperture) to achieve a shallower DOF, or a larger number (smaller aperture) to increase DOF.

Question 4

A small aperture(f-number) is used to keep both the

Answer 4

foreground and background in focus

Question 5

How do you separate the subject from the background?

Answer 5

A shallow DOF (Depth of field)

Question 6

When thinking about f-stop, choose a smaller number to achieve?

Answer 6

a shallower DOF

Question 7

When thinking about f-stop, choose a larger number to

Answer 7

increase DOF

Question 8

A larger aperture has a _1__ f-number and a small aperture has a __2__ f-number.

Answer 8

1. small f-number

2. larger f-number

Question 9

What is a shutter speed?

Answer 9

A camera’s shutter opens to allow light in.

Question 10

Where does the shutter live?

Answer 10

Right in front of the imaging sensor and the shutter speed is the amount of time it stays open, like 1/60 second.

Question 11

What does shutter speed control?

Answer 11

Shutter speed controls how motion is captured by the camera.

Question 12

A fast shutter speed will

Answer 12

freeze moving objects in their track.

Question 13

A slow shutter speed will

Answer 13

is used to take a steady picture without a tripod.

Question 14

How do you achieve long-exposure photography

Answer 14

Slower shutter speeds lead to long-exposure photography. This is how you can blur things like waterfalls or create star trails in the night sky.

Question 15

Slow shutter speed will add

Answer 15

motion blur to any moving elements in the frame, such as water and foliage, while stationary objects will remain sharp.

Question 16

If you are using a very slow shutter speed, make sure your camera is

Answer 16

stabilized on a tripod or other surface to prevent camera shake.

Question 17

When hand holding your camera, the slowest shutter speed you can shoot with out introducing shake depends on

Answer 17

many factors, including the focal length of your lens and whether or not it has image stabilization.
A shutter speeds between 1/60 and 1/25 second (or faster) are safe for handheld shots.)

Question 18

What is ISO?

Answer 18

International organization for standardization. aka film speed. It is a rating carried over from the film days, but means the same thing on digital cameras.

Question 19

What does ISO control?

Answer 19

How the sensor responds to the light it receives from the shutter and aperture.

Question 20

A high ISO leads to a

Answer 20

brighter image

Question 21

A low ISO leads to a

Answer 21

darker image

Question 22

When you increase the ISO you also increase

Answer 22

noise. When you hear someone describe a photo as being “too noisy,” ISO is likely to blame.

Question 23

Why would you want to keep your ISO as low as possible while still achieving the correct exposure?

Answer 23

Because it increases the noise

Question 24

Do sensors perform better at low ISO settings?

Answer 24

Yes. It records better color depth and dynamic range as well.
(In the film days, high ISO films were “grainier.” You can think of “grain” and “noise” as being effectively the same thing.)

Question 25

In daylight or well lit scenes, the ISO can be set low usually around

Answer 25

100 to 400. | In such cases, you can typically rely on just your aperture and shutter speed to dial in a proper exposure.

Question 26

In dim lighting, there may be no other option than to increase ISO. If you want both a fast shutter speed and deep depth of field (small aperture),

Answer 26

then raising the ISO might be necessary.

Question 27

Most cameras start at ISO ___ or ___.

Answer 27

100 or 200, and can be set up to 12,800 or higher. The math is, fortunately, simple: Double the ISO, and you double the brightness, so ISO 800 is twice as bright as 400, which is twice as bright as 200, etc.

Question 28

T or F. Investing in a lens with a wider maximum aperture will help you shoot people in low light to prevent visible noise.

Answer 28

True

Question 29

What three things needs to work together to properly expose an image?

Answer 29

Aperture, shutter speed, and ISO. A change to one will impact the other two. For example, increasing the shutter speed will need to be matched by an increase in ISO or aperture size to maintain the same exposure value. Likewise, decreasing the size of the aperture (selecting a larger f-number) will require a faster shutter speed or lower ISO.

Question 30

When it comes to the aperture setting, think of the opposite: A __1__ f-stop number equals a large aperture setting, while the __2__ f-stop number equals a small aperture setting.

Answer 30

1. small | 2. large

Question 31

To blur the background of a portrait, choose a ____ aperture

Answer 31

large (small f-number)

Question 32

To keep the entire image in-focus, choose a ____ aperture setting

Answer 32

small (large f-stop)

Question 33

To "freeze" a moving object, use a ____ shutter speed.

Answer 33

fast

Question 34

For a blurring effect, use a ____ shutter speed.

Answer 34

slower

Question 35

To reduce noise, try to always keep ____ as low as possible.

Answer 35

ISO. but you may have to raise it in low light settings.

Question 36

Changing one setting affects the others. If you are using a slow shutter speed, you'll likely need to use a

Answer 36

smaller aperture to compensate

Question 37

If you don't mind handing over some control to the camera, choose _____ _____ mode to only control depth of field.

Answer 37

Aperture Priority

Question 38

If you don't mind handing over some control to the camera , choose ____ _____ mode for motion capture.

Answer 38

Shutter priority

Question 39

SLR

Answer 39

Single Lengs Reflex System

Question 40

Tell me about SLR Cameras.

Answer 40

SLR cameras have interchangeable lenses, light comes through the lens and it comes to the mirror. There's one lens. Reflex means there's a mirror in this device and so there are other devices like a reflex telescope which uses a mirror system in it.' So we're gonna bounce the light upward onto a focusing screen, so an image is projected onto that and we're gonna be able to see that through the prism system of the camera.
