10.30: Aperture and Depth of Field

10.30 Aperture Article

Good morning, Photojournalists!

Today's assignment is much like the Shutter Speed Articles you did before. You'll get a paper to fill out as you work your way through this blog posting.

Let's explore the creative possibilities and limitations of exposure through Aperture.

The aperture is the size of the opening that allows light to hit the sensor. It controls the amount of light through the size of the opening.

Aperture is one of three variables that determine exposure (along with shutter speed and ISO) as illustrated in the exposure triangle (actioncamerablog.com)

Depending on how big or little your aperture is affects the depth of field in your image.

Read the following article on Aperture and then answer the questions on the shutter speed handout. 

Then

Aperture and Depth of Field on flicker and you’ll find wonderful examples of photographs that creatively play with fast and slow shutter speeds. 

FIND TWO COOL EXAMPLES OF AND PUT IT ON YOUR BLOG AND TELL ME WHY YOU THINK THEY'RE COOL.

THE QUESTIONS AND POSTINGS ARE DUE BY THE END OF THE HOUR.

10.17.19: Your experiment with shutter speed

Good morning, photojournalists,

Today is senior portrait make-ups, so we're meeting in the LMC.

You'll need to do the following assignment.

You'll need to put this on your blog.

Download the photos you took yesterday. The ones that followed this list:

What you need to do is look at each photo. Open the photo in PhotoShop (you can hold down the command key and then choose "open with PhotoShop"

Once you get them all opened, you need to look at the camera information about the photo. Go under "File" and then down to "File Info..."

 Once you get that window, select "Camera Data," and you'll get a window like this:

This tells you all sorts of information, like what brand of camera you used, what model, what lens, when the photo was taken, etc.

It also tells you what your shutter speed was and what the aperture (the number that says "f/----" is the aperture).

Record the shutter speed and aperture, then look at your photos. What do you notice about the shutter speed and aperture? What changes about the aperture when you change your shutter speed? What do the photos look like?

Put EVERY photo (once for each of the shutter speeds) on your blog. Then under EACH photo, put the shutter speed and the aperture.

THEN under each photo, write a short paragraph about what the shutter speed did to the photo.

THEN AT THE END, write a long sentence OR short paragraph discussing what happened with the aperture when you made the shutter speed shorter.

AND your final part of the assignment is to have a great day!

10.11.19: Canon Outside of Auto- Shutter Priority Mode

Happy Friday, Photojournalists!

It's finally turning chilly, and I'm loving this weather!

You have an assignment for today:

Using the Canon Outside Of Auto website IN SHUTTER PRIORITY MODE, you need to take three photos and put them on your blog.

Go to http://www.canonoutsideofauto.ca/play/

Choose Shutter Priority Mode:
Notice at the top of the screen in the middle the "Shutter Priority(Tv)" clicked.

Now you need to take these three photos:

• one photo with a shutter speed set to where the propeller almost disappears
• one photo where the middle of the propeller appears to be still and the ends are moving
• one photo where the propeller is completely frozen. 

Screen shot each photo SHOWING THE SETTINGS and put them on your blog.

For EACH photo, write a sentence illustrating that you understand the effect that shutter speed has on movement in the photo.
MAKE SURE YOU USE THIS VOCABULARY IN YOUR EXPLANATIONS:

• Long shutter speed OR slow shutter speed
• Short shutter speed OR fast shutter speed
• Frozen motion
• Capture blur

THIS IS DUE ON YOUR BLOG BY THE END OF THE DAY TODAY.
