Back to Basics Part 2

• By Nathan Silvers

2
What we are addressing today

• Review f-Stop
• Jpeg, TIFF, Raw
• Shutter speed

3
Files Types for Shooting

• There are now 3 types of files
• JPEG
• Tiff (new on Nikon)
• Raw
• Each has its advantages and disadvantages
• Your needs determine which is better

4
Jpeg How it works

• You shoot the picture
• Image is sent to processor
• Processor interprets data
• Colors that are close to the same tone are made
  the same
• Unused data is stripped
• Image is saved

5
Jpeg

• Advantage
• Small file size
• Easy to share with others
• More photos on a card
• More photos in rapid fire

• Disadvantage
• Lots of data lost at shooting
• Data is lost every time you save the image
• Loss of data that data can never be recovered
• Harder to recover shadows or especially high
  lights
• You have less control because of interpretation

6
Tiff How it works

• You shot the image
• Image sent to processor
• Processor interprets data
• Image is saved

7
Tiff

• Advantages
• Smaller file size compared to raw
• No data is lost each time you save

• Disadvantages
• Some data is lost at shooting
• Larger files size the jpeg
• Still difficult to recover shadows and highlights
• Image is still a interpretation

8
Raw How it works

• You shoot the images
• Image is saved

9
Raw

• Advantages
• No data loss
• Easy to recover shadows and high lights
• Provides the best workable images

• Disadvantages
• Huge file size
• Storage of files
• Slows systems down

10
Shutter Speed

• This is how long the sensor or film will be
  exposed to the image.
• A long time frame would be 20 on your camera and
  reality 1/20th of a second.
• A short time frame would be 1000 on your camera
  and reality 1/1000 of a second

11
Shutter Speed Rules of Thumb

• General Rule to follow
• Any speed below 1/30 of a second the photography
  should use a tri-pod
• Telephoto Lens Rule
• Take the reciprocal of the focal length and that
  is the lowest you can hand hold that lens.
• Example
• 100mm 1/100 of a second
• 300mm 1/300 of a second

12
Shutter Speed Project

• Goal Explore the effects of different shutter
  speeds on a moving object
• Setup
• Place yourself safely next to the street
• Focus your camera on the area in front of you and
  turn off you auto focus
• Practice following passing cars and pressing the
  trigger without stopping the motion.

13
Shutter Speed Project

• Procedure
• Set you camera to a shutter speed of 1/30 to 1/50
  of a second
• Adjust your f-Stop to achieve the proper exposure
  (The reverse of last time)
• Now using that following technique shoot a car as
  is goes past.

Shutter Speed Project

• Procedure
• Set you camera to a shutter speed of 1/100 to
  1/200 of a second
• Adjust your f-Stop to achieve the proper exposure
  (Notice how the f-stop number has changed)
• Now using that following technique shoot a car as
  is goes past.

Shutter Speed Project

• Procedure
• Set you camera to a shutter speed of 1/500 to
  1/1000 of a second
• Adjust your f-Stop to achieve the proper exposure
  (Notice how the f-stop number has changed)
• Now using that following technique shoot a car as
  is goes past.
