Depth of Field – The two types
What makes these two different?
Depth of Field
-Affected by Aperture (lens opening)
• Small / Shallow
• Large / Deep

Landscape mode
Aperture = Amount of light
• On the iPhone, the aperture is a fixed size so this
can’t be used to change exposure.

DOF influenced by;
– Aperture size (opening in lens)
– Focal Length of the lens
– Distance between the lens and the focus ...
Depth of field affected by
Shutter Speed
• How long shutter is open for determines how
much light reaches the sensor.
SUPER FAST!!
SLOW!!
Effects of Shutter Speed
Shallow Depth of Field
-Also know as
“small”
-Main subject in
focus
-Background is
blurred
Shallow DOF
-Isolates the
subject from its
background and
foreground.
-Focal Point is
obvious, the
subject.
• Popular in sports, portrait, nature photos.
Shallow DOF
• Much of scene is in focus.
• focus range covers a large
area front-to-back
Large/Deep Depth of Field
• Often associated with landscape photography

Depth of Field & Camera (Iphone)

Did you capture a focal range?
Did anyone need to adjust the exposure?
2nd part to this project -
Element of Art, TEXTURE
• The surface quality or
“feel” of an object.
• Smoothness, roughness,
...
Everything has a texture!
• Texture can be:
– Rough
– Bumpy
– Slick
– Scratchy
– Smooth
– Silky
– Soft
– Prickly
Tactile Texture
Let’s focus on
Rough Texture
• Course
• Feels bumpy
• Not smooth
• Rocky
• Irregularities
• Coarse/shaggy
Rough Texture – Shallow DOF
Warm Up #1: Shallow D.O.F. & Rough Texture

PART 1: Wed./Thurs. (In Class)
Take a 4 photos of 4 different rough
textures ...

So…. Look anywhere & everywhere
What will make your photo EYE-CATCHING?
Avoid the obvious and take risks!
What will catch your eye…?
Sometimes it’s not so pretty 
Can have rough texture alongside

Depth of field and texture

  1. 1. Project #2: Depth of Field & Texture • Depth of Field (DOF): front-to-back zone in a photograph where objects appear acceptably sharp. • DOF is also known as “focus range”.
  2. 2. Large/Deep D.O.F. Small/Shallow D.O.F. Depth of Field – The two types What makes these two different?
  3. 3. Depth of Field -Affected by Aperture (lens opening) • Small / Shallow • Large / Deep Portrait mode Landscape mode
  4. 4. Aperture = Amount of light • On the iPhone, the aperture is a fixed size so this can’t be used to change exposure. • However, shutter speed and ISO can be altered to manually adjust the exposure of a photo. (VSCO app.)
  5. 5. DOF influenced by; – Aperture size (opening in lens) – Focal Length of the lens – Distance between the lens and the focus point Portrait Mode Landscape Mode
  6. 6. Depth of field affected by Shutter Speed • How long shutter is open for determines how much light reaches the sensor.
  7. 7. SUPER FAST!! SLOW!! Effects of Shutter Speed
  8. 8. Shallow Depth of Field -Also know as “small” -Main subject in focus -Background is blurred
  9. 9. Shallow DOF -Isolates the subject from its background and foreground. -Focal Point is obvious, the subject.
  10. 10. • Popular in sports, portrait, nature photos. Shallow DOF
  11. 11. • Much of scene is in focus. • focus range covers a large area front-to-back Large/Deep Depth of Field
  12. 12. • Often associated with landscape photography
  13. 13. Iphone – Camera TAP AND HOLD – to lock and manually focus on an area
  14. 14. Iphone – Camera - Exposure Sun icon = Exposure -Swipe up for more light - automatically applies a suitable shutter speed and ISO setting to get the exposure you want. Exposure: determines the amount of light that reaches the camera’s sensor, and therefore affects how bright or dark the photo will be.
  15. 15. Depth of Field & Camera (Iphone) • https://www.youtube.com/watch?v=bJbvQJFGnfg
  16. 16. Let’s try to capture a shallow depth of field with your keyboard! Part 1: Iphone/camera on phone -Try similar angles (above & on right) -Try auto focus and auto lock focus -Adjust exposure Part II: Point and shoot cameras try both -Portrait mode -Landscape mode
  17. 17. Did you capture a focal range? Did anyone need to adjust the exposure?
  18. 18. 2nd part to this project - Element of Art, TEXTURE • The surface quality or “feel” of an object. • Smoothness, roughness, softness, etc.
  19. 19. Everything has a texture! • Texture can be: – Rough – Bumpy – Slick – Scratchy – Smooth – Silky – Soft – Prickly
  20. 20. Tactile Texture
  21. 21. Let’s focus on Rough Texture • Course • Feels bumpy • Not smooth • Rocky • Irregularities • Coarse/shaggy
  22. 22. Rough Texture – Shallow DOF
  23. 23. Warm Up #1: Shallow D.O.F. & Rough Texture . PART 1: Wed./Thurs. (In Class) Take a 4 photos of 4 different rough textures using a shallow depth of field. 1. 4 different objects with ROUGH texture. 1. Use a SHALLOW DEPTH OF FIELD, so more of the image is in focus allowing the textures to be emphasized. *Distance from object effects the depth of field! 4. If comfortable, you can try adjusting ISO, shutterspeed, and aperture. You can use the VSCO app. to do this. We will focus more on this in later classes.
  24. 24. Project #2: “Eye-catching” - Shallow Depth of Field & Rough Texture • Due on Tuesday, Sept. 6th • PLEASE take these outside of school. I can usually tell • Take 5 photos (or more) of using a shallow depth of field. • Find objects that represent the element of art, texture. Focus on rough textures only. • The theme of the project is “eye-catching”. Take photographs of object(s) that catch your eye. Of course, keep in mind you are focusing on textures and shallow depth. • Remember the rule of thirds! ie. Not centering the main subject.
  25. 25. So…. Look anywhere & everywhere
  26. 26. What will make your photo EYE-CATCHING? Avoid the obvious and take risks!
  27. 27. What will catch your eye…?
  28. 28. Sometimes it’s not so pretty 
  29. 29. Can have rough texture alongside another object that’s opposite. Smooth and Rough
