This document provides information about depth of field and texture in photography. It discusses how depth of field is affected by aperture size, focal length, and distance to the subject. A shallow depth of field blurs the background and foreground to isolate the subject, while a deep depth of field keeps a large area in focus. Texture refers to the surface quality of objects, like rough, bumpy, or smooth. The assignment asks students to take photos of rough textures using a shallow depth of field to emphasize the textures and make them eye-catching.

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. Large/Deep D.O.F. Small/Shallow D.O.F.
Depth of Field – The two types
What makes these two different?

3. Depth of Field
-Affected by Aperture (lens opening)
• Small / Shallow
• Large / Deep
Portrait mode
Landscape mode

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. 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. Depth of field affected by
Shutter Speed
• How long shutter is open for determines how
much light reaches the sensor.

7. SUPER FAST!!
SLOW!!
Effects of Shutter Speed

8. Shallow Depth of Field
-Also know as
“small”
-Main subject in
focus
-Background is
blurred

9. Shallow DOF
-Isolates the
subject from its
background and
foreground.
-Focal Point is
obvious, the
subject.

10. • Popular in sports, portrait, nature photos.
Shallow DOF

11. • Much of scene is in focus.
• focus range covers a large
area front-to-back
Large/Deep Depth of Field

12. • Often associated with landscape photography

13. Iphone – Camera
TAP AND HOLD – to lock and manually focus on an area

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. Depth of Field & Camera (Iphone)

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. Did you capture a focal range?
Did anyone need to adjust the exposure?

18. 2nd part to this project -
Element of Art, TEXTURE
• The surface quality or
“feel” of an object.
• Smoothness, roughness,
softness, etc.

19. Everything has a texture!
• Texture can be:
– Rough
– Bumpy
– Slick
– Scratchy
– Smooth
– Silky
– Soft
– Prickly

22. Tactile Texture

24. Let’s focus on
Rough Texture
• Course
• Feels bumpy
• Not smooth
• Rocky
• Irregularities
• Coarse/shaggy

25. Rough Texture – Shallow DOF

26. 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.

27. 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.

28. So…. Look anywhere & everywhere

29. What will make your photo EYE-CATCHING?
Avoid the obvious and take risks!

30. What will catch your eye…?

31. Sometimes it’s not so pretty 

32. Can have rough texture alongside
another object that’s opposite.
Smooth and Rough
