10:05 Today’s Notes & Attendance

Today is a CTE Blue Day – afternoon classes begin at 1:25pm

CCV Classes on Friday- We are meeting in the lobby. You must check-in with Ms. Charron by 9:55 first. EHS Lobby. Bus leaves at 10am sharp. Don’t miss your first day. Questions?

Fill out Lunch Form so a lunch will be waiting for you after CCV

We have a fire drill today – about 10:15

PE class held meeting in Room c121

Production time this morning until the drill:

Abstract Photography Slideshow with Metadata
Champ Challenge (for those here yesterday afternoon)
C.R.A.P

10:15 Fire Drill

We’ll go to our usual spot – which is at the back of the parking lot.

10:25 Photography – Review & Learning about Aperture

Yesterday you learned through practice that the easiest approach to abstract photography is the close up shot. Close-ups remove the context of what is in the viewfinder as well as emphasizes the texture and graphic elements.

We also talked about Focal Length.

Focal Length is the space from the camera sensor to the lens. This measurement is measured in millimeters.

Wide Lens – 35mm
Normal Lens – 50mm
Telephoto Lens – 75-300mm

Focal Length is measured in Millimeters and it represents the distance from the center of the camera’s lens to the sensor of the camera body. The longer the distance, the longer the lens, and the longer the zoom.

Why does the Focal Length Matter? Well, focal length will help you:

Determine your Field of View. When you change the focal length, the field of view will change. More or less will show in the viewfinder.
Perspective – Objects behind an image will be compressed with longer focal length
Depth of Field is affected by focal length
1. shallow DOF – small or narrow area is in focus
2. long DOF – more in focus

Aperture

To control focal length, let’s learn about Aperture Priority mode.

Aperture is the space through which light passes into the camera

Your Camera has an Aperture Priority Mode!

Remember, in Aperture Priority mode, you have control over the Focal Length which is referred to as the lense field of view. Cheat Sheet

A small f-stop number (f2) means a small depth of field and large f-stop number (f22) means a large depth of field.,

Can you think of some shooting scenarios where you would want to adjust the aperture?

Confused Yet?

10:50 Break

11:00 Blender

A really good way to get an understanding of focal length, depth of field and f/stops is to set up a model in Blender and play with all the the camera settings to see how things work.

If you have not been in Blender for awhile, no worries. I’ll take you through, it will be like riding a bike.

11:25 Shutter Priority (Tv)

Link to Photography Terms & Concepts

Shutter Priority mode allows you as the photographer to take charge of the speed of the shutter. To review, when you press the button to take a picture, the photo become exposed and the shutter closes when the exposure is complete.

The photo above is a classic example of motion blur using Shutter Priority mode.

The slower the shutter speed the more light is received by the image sensor.

The faster the shutter speed, the less light hits the sensor.

Let’s brainstorm some reasons why we would want to try shooting in Shutter Priority…

Back to Blender…

Blender’s camera is not like our real camera. The Blender camera is a simulation. That means that Shutter speed is not part of the actual camera in Blender. Rather, shutter speed is part of Motion Blur which is found in the render settings. Let’s continue with our model…

Some settings in Motion Blur to consider (in Blender):

Position:

Center middle frames of animation
Start frames of animation
End frames of animation

Shutter:

.01 is one hundredth of a second
.5 is a half second
1 is one second

In class we’ll look at your camera settings for shooting in Shutter Priority mode.

Big Questions?

How does light impact your images when shooting in Shutter Priority?
How can you eliminate camera shake?
What is the exposure triangle? For that matter, what is exposure?

Activity: Using Shutter Priority and with a partner, Capture:

Partner running – freeze action
Partner running – blur action
Pan and Blur (pan one direction while the action – partner moving is going another direction)
Close Up of flower with slow shutter speed
Close Up of flower with fast shutter speed
Slow shutter camera swirl (pick your subject)

Return to the classroom, import and review. Practice using Adobe Bridge to review your shots and to do some editing.
Before Lunch, post your favorite shot of the bunch…
