10:10 Scrum Meeting

Let’s talk about where we are at…

10:15 Aperture and Shutter Priority in Photography

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. From our activity yesterday a nice blurry background is more pronounced when we have our primary subject close and it fills the frame.

small f/stop numbers usually have narrow or shallow depth of field as seen in first image
large f/stop numbers create a deep depth of field as seen in the second image

10:25 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…

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.

While we are at it, we can also play with shutter speed!

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

10:50 Morning Break (10 minutes)

11:00 Fundamental Programming with C# & Unity

Each Wednesday we’ll do a little programming to get more familiar with the Unity interface and help each of you get more comfortable with game programming. This practice will translate well when we get to SkillsUSA work and our full game unit next semester. I promise to keep the coding manageable!

Last week we looked at variables – specifically int which are whole numbers, float which are decimals and string which are for words, phrases etc…

We also learned that variable scope refers to where you place your variables. If you placed your variable in the Start method, it will run when the game begins and then not be accessible again. If you place your variables at the top of your code, they are available across methods and functions.

Public variables are accessible from game play and from other scripts. Private variables, which is the default for variables are available only for that script.

[SerializeField] is a private variable type but is available from game play to adjust while testing

Check out all the variables in the gameboard above!

public class MyScript : MonoBehaviour {

   int score;               // declare an int called Score
   float currentDirection;  // declare the float currentDirection
   char myInitial;          // declare a char called myInitial
   string userName;         // declare a string called userName
   bool isMoving;           // declare a bool called isMoving

   void Start () {

      //  numeric data types do not require quotes
      score = 8;

      // use the "F" suffix to specify a float value    
      currentDirection = 90.2F;    

      // use single quotes around individual characters
      myInitial = 'A'; 

      // use double quotes around groups of characters
      userName = "Will Bohmann";  

      // boolean values are either true or false 
      isMoving = true;        
   } 
}

We already know that we use variables to provide more code flexibility. In many cases we may want to store mathematical operations in a variable. Let’s look at some common math operations.

int added = 3 + 4;          // added is 7
int subtracted = 3 - 4;     // subtracted is -1
int multiplied = 3 * 4;     // multiplied is 12
int divided = 12 / 4;       // divided is 3
int remainder = 12 % 5;     // remainder is 2

12:05 Working in Shutter Priority

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
Partner jump – freeze action
Partner jump – blur action
Close Up of flower with slow shutter speed
Close Up of flower with fast shutter speed
Slow shutter camera swirl

Return to the classroom, import and review. Practice using Adobe Bridge to review your shots and to do some editing with Camera Raw or Photoshop.
Before Production, post your favorite shot of the bunch… Be prepared to say why
