Why?

6Why do we take photos?

Light

Twitter: @Tibbon8

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

4 Important Settings

• Aperture

• Shutter

• Focus

• ISO/Sensitivity/Film Choice

Twitter: @Tibbon13

Exposure

= Amount of light hitting sensor

Twitter: @Tibbon14

Shutter Speed = Time shutter allows light to

sensor

Twitter: @Tibbon15

Faster Shutter SpeedLess light hits sensorRequires more light

Sharper imageLess Blur

Freezes motionExample, 1/2000th second

16

Slower Shutter SpeedMore light hits sensorBetter for dark/night

Less sharp imageMore blur

Can convey motionExample, 1/30th Second

17

Aperture=

Size of Lens Opening

18

Large Opening (f/1.2)19

Small Opening (f/8)20

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

Narrow DoF: f/1.622

Wide DoF: f/823

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

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

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.

Problem Solving

30

They give us the vocabulary for problem solving skills.

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.

Complex Situations

32

Bloggers encounter complex situations often in photography.

Simply & Analyze

33

These terms allow us to analyize and simply photographic situations.

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.

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.

4 Mode Settings

• Program (automatic)

• Shutter Priority

• Aperture Priority

• Manual

36

Problem?

37

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

What is important?

38

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

Choice

39

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

Aperture setting

40

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

Not enough light?

41

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

Flash!

42

Then flash can be the answer

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.

Buying a Camera

45

Most salespeople are poorly informed

46

How many Megapixels?

47

Looks good to me!48

2.74MP

49

Megapixels DONT matter

50

Don’t ask them general questions!

51

What do you want to do?

52

• People

• Sports

• Video

• Professional

• Landscapes

53

Weight

54

SLRs are heavy

& BIG55

Megapixels don’t matter.

56

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.

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?
