Shutter Speed - Capturing Movement

The next Element of Exposure we will explore is Shutter Speed.

Shutter Speed is - The amount of TIME you let light into the camera.

Shutter Speed is measured in seconds or fractions of a second.

For example:

1" = 1 second

1/2 = 1 half second

1/125 = 1 one hundred twenty-fifth of a second

A Shutter Speed of 1 second is considered SLOW, and as it moves into fractions of a second, such as 1/125, the Shutter Speed is described as FAST.

By changing shutter speeds you not only control how long light enters the camera but also how motion is captured in your image. You can Freeze the movement of your subject, Show Motion Blur, or Track your subject.

Here is an example of how shutter speed shows motion blur or freezes action.

Use the Thumb dial to set the Shutter Speed. In the screen below, the Shutter Speed is set at 1/60, or one sixtieth of a second. 1/60 is basically a dividing line between slow and fast shutter speeds.

Follow this link for a description of how shutter speed works.

We will now have a hands-on practice session and I will demonstrate how to change the Shutter Speed on the Nikon DSLRs.

Next you will practice taking

Today we will use various shutter speeds to:
1. Freeze motion (fast shutter speed of 1/125 or higher)
2. Create a Motion Blur (Shutter speed around 1/15 or slower)
3. Tracking - Panning (Shutter Speed about 1/60)

ISO Experiment

Set your Shutter Speed to 1/250 and your Aperture to f 11. I will help you do this.

Today we will take a walk and the same picture  at every ISO setting from 100 to HI 2.

Post the pictures to a blog post titled ISO Experiment. Make sure to label each photo with the correct ISO.

Here is an example:

ISO - The Cameras's Sensitivity to Light

ISO is  how sensitive the sensor in the camera is to light.

Low ISO = Low Sensitivity to Light
High ISO = High Sensitivity to Light

The ISO numbers double as they increase: 100 - 200 - 400 - 800, etc. Notice that this means each setting makes the camera twice as sensitive to light as the previous setting.

The ISO ranges from 100 to 3200 and above. There is also a "High 01" and High 02" setting.

Here are some links that go into greater detail about ISO.

You should always try to use the LOWEST ISO POSSIBLE to obtain the best quality image.

The 3 Elements of Exposure

Exposure is the action of letting a certain amount of light into the camera through the lens for a certain amount of time. The light then hits the camera sensor and the image is captured.

There are three basic elements to Exposure:

• ISO - The Camera's sensitivity to light
• Shutter Speed - The time (in seconds) that light is allowed into the camera
• Aperture - How much light is allowed into the camera

We will learn about each of these elements of Exposure over the next few weeks.

Help me choose a camera!

I am need of a camera but I don't know what kind I want or need.

At your table please do some research for me and give me three options:
A cheap simple camera
a middle of the road camera
a high end camera 

Go to amazon.com and find an example of each, and then tell me the price, and pros and cons of each type of camera. include a link to each of the cameras.

You can work as a group, but you all need to put your answers in a post on your personal blog.

We'll discuss your decisions in about 15-20 minutes.

3 Types of Digital Cameras

There are many different types of digital cameras. Which one you choose will depend on how much control you want over your photography and price.
These links do a good job of describing the various types of cameras available.

http://www.circuitstoday.com/different-types-of-digital-cameras
http://easybasicphotography.com/Types-of-cameras.html

The articles above explain that there are three types of digital cameras, Point and Shoot, Bridge, and DSLRs. You need to know the differences and advantages and disadvantages of each type.

We will be using Nikon DSLRs in class. 


You need to know and demonstrate the following:

• Find the Mode Dial
• Locate and explain the various settings on the Mode Dial, including P, S, A, M and the Auto modes
• Find the Information Display, and locate and click on the ISO, Aperture, and Shutter settings within the display.

This is a new post

hello...

Are You Taking a Snapshot or a Photograph?

Review the following articles....

Snapshot or Photograph, what is the difference?

What constitutes landscape photography over that of a snapshot?

For your first blog post,  discuss the important aspects of these articles. Answer
the following questions...

What are differences between a snapshot and a photograph?
What are the advantages and disadvantages of each type?
Do you agree or disagree with the author's definitions?? Explain your answer.
Can a snapshot ever qualify as art? Why or why not?

Create Your Blog

Today we will each use blogger to create our own blog for this class.

You will upload projects and document your progress as you work throughout the semester. This is where you will also upload your final portfolio.

You automatically have an account in blogger because you have your school google account. You will use the same login and password as your Ozark google mail.

We'll do this together and i will walk you through the process. Hint... if you took my Art foundations class last year then you've already done this! 

Let's get started! 

Create a new blog and create the web address in the following format:

firstnamelastinitialphoto15afall19

for example: johncphoto15afall19

You may title the blog however you'd like.

When you are done email the address of your blog to me at johncazort@ozarktigers.org

PLEASE USE A SIMPLE THEME!!!!!

Welcome to Photo 1! Please Bookmark this Blog!

Welcome to class! Prepare yourself to be challenged both creatively and technically!

Please go to this blog address and bookmark it! All of our information will be here:

http://ohsphoto15afall19.blogspot.com

Next we'll go over the syllabus and projects for the semester, and then we'll each set up a blog. 

After you create your blog send the address to me at johncazort@ozarktigers.org
