2016 High School Communication Conference

Camera Skills

Apertures,Shutters,ISOs…“OH MY!”

Presented by

David Blake, Photographer & Debbie Chojnacky, Borah Photography Slide2

Are you

overwhelmed, confused or terrified by these controls on your Camera?

“Help is here!”Apertures, Shutters, ISOs…“BOO!”Slide3

“READY? SET? LET’S GO!”Slide4

Camera

SkillsCamera Shutter

The camera shutter controls how long light enters the camera. A fast shutter speed is 1/1000 of a second. A slow shutter speed is 1/2 of a second.Slide5

Shutter speed

A fast

Shutter Speed

can stop action.

A slow

Shutter Speed

can blur action.Slide6

Stopping Action

For Sports, use a “fast” shutter speed, like 1/500 or 1/1000 to stop action

.

Hummingbird wings requires a shutter speed in excess of 1/10,000 second

to stop action, which

is not possible for most cameras.

Using an external flash can stop Hummingbird wings because flash durations are typically 1/35,000 second. Slide7

Shutter speed

Q:

Is this

shutter set

closer to 1/2 sec. or 1/1000 sec.?Slide8

Shutter speed

Is this shutter set closer to 1/2 sec. or 1/1000 sec.?Slide11

Camera

SkillsAperture and F-stop

Aperture regulates the size of the opening in the lens.F-stop measures the size of the aperture or opening.The bigger the F-stop the smaller the opening.F-2 is an “open” stop – lets in more light.

F-22 is a “closed” stop - lets in less light.Slide12

F-stop

Double

the F-stop = 1/4 the Light Half the F-stop = Quadruple the LightSlide13

Depth-of-Field and F-stops

Depth-of-Field = Amount in FocusSmaller F-stop = Less Depth-of-Field (less in focus)

Larger F-stop = More Depth-of-Field (more in focus)Slide14

Depth-of-Field

Q:

How does Depth-of-Field change the photograph?Slide15

Depth-of-Field

Q:

Is this closer to f/2 or f/22?Slide16

Depth-of-Field

Q:

Is this closer to f/2 or f/22?Slide17

Camera

SkillsExposure

Exposure is the amount of Light used to take a picture.Over-Exposure = Picture is too Light.

Under-Exposure =

Picture is

too Dark.Slide18

Camera

SkillsExposure

Exposure is controlled by the aperture and the shutter.Slide19

Exposure

See-Saw…Slide20

Exposure and ISO

ISO adjusts the cameras sensitivity to light.The higher the ISO, the less light is needed.

The higher the ISO, the higher the image noise.Slide21

ISO

Setting

ISO measures the sensitivity of the image sensor. The lower the number the less sensitive your camera is to light and the finer the grain. Slide22

ISO

Setting

ISO is visible on the camera display. Depending on the DSLR, ISO settings will range from ‘auto’ , 100 – 1800 or more!Slide23

Camera settings

settings for Aperture, Shutter & ISO..Slide24

Camera settings

This Chart Illustrates an AV (aperture priority) camera mode setting with a larger F-stop, ISO of 400.Slide25

Let’s practice Camera settings!

Here is another camera simulator original web site! Learn, Practice and Challenge yourself before you Go!Slide27

This is a simulation setting that I did! My goal was to have child & pinwheel freeze (stop moving) … in MANUAL

setting! See if you can get to this outcome.Hey! Thanks for attendingCamera skills!
