A presentation I gave at Podcamp Pittsburgh 3 as a crash course for photography for bloggers. Mainly covers exposure based subjects.

6. Why?

Why do we take
photos?

7. Communicate

8. Light
Twitter: @Tibbon
8
What do we capture?
Light.
Everything is a function of light coming into the camera. This is why photos in the dark don’t work well. Without light there is no photo

What are we taking the photo
of?

12. Sensor (digital)/Film
Twitter: @Tibbon
12

13. 4 Important Settings
• Aperture
• Shutter
• Focus
• ISO/Sensitivity/Film Choice
Twitter: @Tibbon
13

14. Exposure
= Amount of light hitting sensor
Twitter: @Tibbon
14

15. Shutter Speed
= Time shutter allows light to
sensor
Twitter: @Tibbon
15

16. Faster Shutter Speed
Less light hits sensor
Requires more light
Sharper image
Less Blur
Freezes motion
Example, 1/2000th second
16

17. Slower Shutter Speed
More light hits sensor
Better for dark/night
Less sharp image
More blur
Can convey motion
Example, 1/30th Second
17

18. Aperture
=
Size of Lens Opening
18

19. Large Opening (f/1.2)
19

20. Small Opening (f/8)
20

21. Aperture
• Aperture is expressed in f-stops.
• Smaller number = more open = more light hits sensor (f/1.2). Narrow
Depth of Field (DoF)
• Larger number = more closed = less light hits sensor (f/8). Deep DoF.
21

22. Narrow DoF: f/1.6
22

23. Wide DoF: f/8
23

24. Using Aperture
• If little light, use largest aperture possible (ex: f/2.8)
• If lots of light, you have choices. Aperture can be used to cut down on
light.
24

25. ISO/Sensitivity
• Sensitivity of film/sensor to light
• Lower numbers (ISO/100) need more light.
• Lower numbers have less grain, higher image quality
• Higher numbers (ISO/3200) need less light.
• Higher numbers have more grain, lower image quality
25

26. Grainy Photo: ISO1600 26

27. Low Grain: ISO100

29. But wait!
29
How does this affect me? How does this work with my camera? I have program modes and a point and shoot. What Aperture and
shutter aren’t skills.

30. Problem Solving
30
They give us the vocabulary for problem solving skills.

31. Easy
31
Taking photos is EASY. We can all take photos. But how do we take good photos? You’re going to have problems at some point
taking photos and you have to have the problem solving skills to get around them.

32. Complex Situations
32
Bloggers encounter complex situations often in photography.

33. Simply & Analyze
33
These terms allow us to analyize and simply photographic situations.

34. Meters
34
A few final things. Most modern cameras have meters. These tell us how much light is coming into the lens, essentially help try
to tell us how much light we need coming into the camera. This helps tell you how to set the aperture, shutter and iso settings
that we just talked about.

35. Programs
35
Which brings us to Program modes. Cameras today are smart and often contain powerful computers that can help guess settings
for us. In many settings these modes can do fine jobs at producing average photos.

36. 4 Mode Settings
• Program (automatic)
• Shutter Priority
• Aperture Priority
• Manual
36

37. Problem?
37
So whats the problem? Why can’t we just use program mode and pull the trigger?

38. What is important?
38
What is important in the photo? This seems like a basic thing, but let’s consider some photos.

39. Choice
39
That is your choice. Let’s look at some photos that illustrate this.

40. Aperture setting
40
I personally use Aperture priority settings 95% of the time.

41. Not enough light?
41
What happens is there simply isn’t enough light to make it happen with these settings?

42. Flash!
42
Then flash can be the answer

43. Lighting is complex
43
Lighting is a complex topic, so I won’t go too much into it asides to say that using it too much can look bad, create harsh
portraits. OFF-camera light looks the best.

This blog will help lead you through all things flash related and tries to not break the bank.

45. Buying a Camera
45

46. Most salespeople are poorly
informed
46

47. How many Megapixels?
47

48. Looks good to me!
48

49. 2.74MP
49

50. Megapixels DONT matter
50

51. Don’t ask them general questions!
51

52. What do you want to do?
52

53. • People
• Sports
• Video
• Professional
• Landscapes
53

54. Weight
54

55. SLRs are heavy
& BIG
55

56. Megapixels don’t matter.
56

57. Lens
57
One of the most important aspects however is the LENS. Good lenses aren’t cheap. If you go with an SLR expect to spend about
as much on decent lenses as you do on the camera body.

58. Egronomics
58
If you don’t like the way a camera feels, then you aren’t going to use it much. For professionals these often become make or
break features. Do you like the way it feels in your hand? Can you figure out the menus easily? Are things marked well? Does the
button placement make sense for you?
