What 2 mechanisms allowlight into a camera?

Aperture and Shutter Speed

Page 3: Camera Basics

SHUTTER SPEED

• Controls the amount of light that is allowed into the camera by the amount of time it is left open

This can effect:-Motion captured--Lightness or darkness of the photograph

Page 4: Camera Basics
Page 5: Camera Basics

Fast Shutter Speed• 1/250, 1/500, 1/1000• The faster the shutter speed, the

more likely it is that you will be able to “freeze” the subject

• ….but also the less light you are letting in

Non-moving subject**

Page 6: Camera Basics

Slow Shutter Speed• 1/4, 1/8, 1/16, 1/30• The slower the shutter speed,

the more likely it is that your subject will be blurred

• ….but also the more light you are letting in

Page 7: Camera Basics

Safest Shutter Speeds

• No lower than 1/30-1/45 s

• If you must take a picture using a shutter speed of 1/30 or below than you need to use a tripod or set the camera on a flat surface.

Page 8: Camera Basics

Slow Shutter = Blurred Motion

1/60, 1/30,1/15, 1/8…….

Page 9: Camera Basics

Fast Shutter = Frozen in Time

1/250, 1/5001/1000, ………..

Page 10: Camera Basics

How to Pan• Set the shutter at about

1/45*• Following the action

while you are taking the picture

• Release the shutter and continue following the action

Page 11: Camera Basics

B• The “B” on your

shutter stands for bulb, this allows the shutter to stay open as long as your finger is on the camera

• Used mostly for night photography

• Use a tripod if you are using the B

Page 12: Camera Basics

Shutter Speed Control Mode-On the Cannons- TV-On the Fujifilms- S

Combat the issue of under exposure with aperture*

Where to find it on the camera

Page 13: Camera Basics

Shutter Speed Review• Give me a thumbs (up down or in the middle) if…

• You remember what shutter speed is

• You remember what type of shutter speed to use if your subject is moving quickly (fast or slow)

• You remember what type of shutter speed lets in MORE light (fast or slow)

• You remember when you should use a tripod

• Bonus: Your remember what the “B” stands for

• Challenge: When in AV/ shutter speed control mode, what your camera changes to combat any exposure issues…..

Page 14: Camera Basics

APERTURE• Aperture refers to the opening of a lens's diaphragm through

which light passes.• Controls how much light comes into the camera (the intensity

of light)• Film Camera Lenses

Page 15: Camera Basics
Page 16: Camera Basics
Page 17: Camera Basics

EYE get it!• Works like an eye• What happens to your pupil when

you go in the dark?• Your eye gets larger to let in more light

• What happens to your pupil when someone shines a flashlight at it?• It gets smaller, doesn’t let as much light in

Page 18: Camera Basics

Aperture= F-Stop= lens opening• F-stop = Focal length/Aperture diameter

• F-stop= F 2.8 – F 22

The f-stop with the LARGEST FRACTION The f-stop with the LARGEST FRACTION is going to let in the MOST amount of lightis going to let in the MOST amount of light

What does changing the aperture do to the photograph?

Page 22: Camera Basics

Depth of Field The area of your photograph that is in sharp focus, the areas in front of and behind your subject

Page 23: Camera Basics

Large (Great) Depth of Field• The subject and the background will be in focus

Small Aperture hole – Think about SquintingLarge Number – F/16 or F/22

Page 24: Camera Basics

Small (Shallow) Depth of Field• The subject BUT NOT the background will be in focus

Large Aperture Hole – Allowing more lightSmall Number – F/2.8 – F/4

Page 25: Camera Basics

How do Depth of Field and Aperture Work Together?

Aperture and Shutter Review• Are the two things that control the amount of light that

reaches the film

• You need a correct combination of both in order to let in the right amount of light

• Shutter speed controls the amount of time light has to enter the camera

• Aperture controls the amount of space light has to enter the camera

• Lets look at the cannons on MANUAL MODE

Page 30: Camera Basics

Manual Modes• Get in groups around the cameras, no more than 3 people to

a camera• Canons first• Now Fujifilms

How do you know if you have to correct amount of light in your camera????

Page 34: Camera Basics

LIGHT METER• Measures light levels within the area you are

photographing

Page 35: Camera Basics

Proper Exposure

Page 36: Camera Basics

Changing the Exposure• To get the proper amount of light (your light meter

reading in the middle) you change aperture and shutter speed.

• Reciprocal System- Once you know the correct combination of shutter and aperture, you can change one setting as long as you change the other setting to match it- i.e. let in the proper amount of light

ISO• International Standards

Organization• It is how sensitive the

camera is to light

Page 40: Camera Basics

ISO• The HIGHER the ISO number ( FASTER film) the more sensitive

the camera is to light, BUT the grainier the image

• The Lower the ISO number the less sensitive the camera is to light, BUT the clearer the image

• IDEAL film is 200/400 (less grainy)• But you need good light

Page 41: Camera Basics

If outside and really bright, set it to 100

If outside and cloudy or dim,set to 200-400

If dark or inside, set it to 800 – 1600

There is a CATCH… grainy
